About tsh

... and its documentation.

tsh is a Perl application for managing Scrabble tournaments, first written in 1999, continuously maintained since then and freely distributed for noncommercial use by John Chew <poslfit@gmail.com>. This document and tsh are copyright © 2014 John J. Chew, III.

tsh is a program that deals with the logistics of running a tournament. With it, you can automatically or manually pair players, enter results, print standings, debug scorecard errors, estimate new player ratings and prepare data submissions for official ratings systems. tsh has been used at dozens of tournaments, producing high-quality pairings and reports with an estimated maximum operator:player ratio of 1:250. Among the many events that have been run using tsh are: the World Championship, the U.S. National Championship, the U.K. National Championship, the Canadian Championship, the U.S. Players’ Championship, and the King’s Cup as well as countless smaller weekend and one-day tournaments throughout the English, Italian, German, Polish and Norwegian Scrabble communities.

tsh comes with detailed documentation describing all of its features. Not everyone needs to read all of this document, and U.K. users in particular should begin by reading Stewart Holden’s Beginners’ Guide to TSH. NASPA users may benefit from reading Vince Castellano’s TSH QuickStart.

If this is your first time using tsh, or if you have not yet used version 3.000 or later, you must read the Introduction. You may then continue with other sections listed at the top of this page. All users should at least skim the section on commands. Data entry staff should read the sections on data entry, generating generating reports and troubleshooting. At least one person at each tournament should have browsed all sections of the manual before the tournament begins, including those on installation, configuration and pairing theory. If you want to print a copy for your reference during the tournament, the entire reference manual is also available in one file.

Before each tournament, you should update your copy of tsh and read the news of what has changed in recent versions, and follow the links there to changes in the other manual sections.

Free telephone support is available by prior arrangement. If you are planning to use tsh at a tournament, please contact me (John Chew) at least a few weeks in advance for help in setting up configuration files, and to discuss your support needs. If there is a specific feature that you need added to tsh, or support for a new language, please ask for it as far in advance of your event as possible. There is also a Yahoo group devoted to the needs of tsh users.

Thank you to recent donors Jason Idalski and Dallas Johnson, Ryan Fischer, and Larry Sherman for their generous support of tsh development.

If you would like to make a donation to help make it possible for me to continue improving and supporting tsh, I welcome them via the “Make A Donation” PayPal button at the bottom of my poslfit home page. Thank you to recent donors Ryan Fischer and Elie Dangoor! I am also available for hire to help run or webcast tournaments and games, on site or remotely, but am frequently booked 6-12 months in advance.

System Requirements

tsh is written in Perl, the multiplatform scripting language. Every released version is tested with OS/X and should therefore also run on common versions of Unix. tsh versions are tested a few times a year with Windows XP, and whenever a user requests it. If you are using an operating system not mentioned here, please allow a few extra weeks for any software changes that may be needed to bring the current version of tsh into compatibility with it.

Disk space and memory requirements are minimal, a fairly small number of megabytes each. One computer is recommended for every 250 or so players, and one networked printer per tournament, though having more of each will reduce data entry and report printing time and improve redundancy.

If an Internet connection is available at the event site, tsh can be used to automatically update web coverage of the tournament, and last-minute patches to the program itself can be automatically downloaded. If not, tsh can run without these features.

Troubleshooting tsh

What to do when things go wrong with tsh.

Installation

It's possible that some OS/X browsers may download a non-executable version of this file. If so, please contact me for instructions. If you can't reach me, move your tsh folder to your home directory, open a “Terminal” window, enter the command “cd tsh-nnnn” replacing “nnnn” with the version number that you downloaded, and finally enter the command “chmod a+x osx*” to mark the command executable.

Some security-conscious users may have their personal firewall settings set too aggressively to allow the “update” command to function. tsh uses only port 80 (the standard port for HTTP service), so it should suffice to add tsh and/or Perl to the list of applications authorized to connect to this service.

If your update command does not seem to work, try the following in order. You may have a corrupt manifest file: move the ‘MANIFEST.txt’ file out of the tsh folder to make tsh lose track of what files it has, rerun tsh and the update. You may be having networking problems: make sure your browser can connect to the tsh web site. You may be having local system resource problems preventing tsh from beginning the update process: try restarting your Windows machine. You may have encountered a problem I didn't expect: download a fresh ZIP archive of either the current development release or the last stable release from the tsh web site, then copy your event folders into it.

Correcting Tournament Data

You can try using the experimental “FIX” command to make many common corrections.

You can delete bad pairings using the “UnPairRound” command, edit scores (and correct who went first, etc.) using the “EditScore” command (if you are in the middle of adding scores and you want to correct the most recently entered game, just type “es” at the game score prompt) and delete bad scores using the “DELETEscore” command. See the command reference for the syntax of those commands.

If you have made a serious error, you can manually revert to an earlier version of any tournament data (“.t”) file. tsh journals a copy of the tournament data file into a subdirectory or folder named "old" after each major change. Quit out of tsh, then look for the last good data file (either by checking the timestamps or inspecting the contents of the files), rename the bad “.t” file to “.t.bad” and put a copy of the journalled “.t.lotsofnumbers” file in its place as a new “.t” file.

You can also edit “.t” files using a text editor such as vim, gVim, BBEdit, TextEdit, NotePad, WordPad or emacs. If you do so, first quit from tsh, because tsh keeps an internal copy of its data that will overwrite any changes you make when tsh next updates its files.

Crashes

If you are testing a new tsh feature, it’s possible that a program bug may put tsh into an infinite loop or dump core. In the former case, when tsh doesn’t give you a prompt, you’ll have to interrupt tsh and restart it. In OS/X and Unix, you interrupt terminal processes by pressing Control-C. In Windows, you can close the window that tsh is running in.

Some early versions of some pairings commands took a very long time to run. It’s possible that some bugs remain undiscovered. If you find that generating pairings in one particular situation takes excessively long (more than a few seconds), you may interrupt tsh, restart it, and then manually enter a faster pairing command. Allowing an extra repeat should in most cases substantially speed up the pairings calculations, or you can use the “PAIR” command to manually pair key players and then a regular command to pair the rest. In any case, in the unlikely event that this happens to you, please e-mail John a copy of the “.t” file involved.

As mentioned above, tsh journals its data after each major command, so if you are unsure about the condition of its files after a crash, revert to the last versions that were saved before the crash.

Players Who Miss Games

The spread value for an unplayed game is given here as ±50 points as per NSA rules. ABSP rules require ±75 instead.

Here was the old way of doing things. For example, if players 1 and 2 in division A were supposed to play each other in round 3 but player 1 didn't show up, then enter “pair 0 1 3 a” and “pair 0 2 3 a” to assign the byes, then when entering scores for division a enter “1 -50” and “2 50” to set spreads.

If a player misses a paired game (e.g. due to illness or tardiness), you should manually repair him and his opponent to assign them both byes, then enter appropriate spreads for their scores. If you don’t do this, the unplayed game will count for ratings, and some players may end up getting multiple byes before others get any. If players 1 and 2 in division A were supposed to play each other in round 3 but player 1 didn’t show up, then enter “floss a 1 3”.

If a player gives you notice that he will be missing one or more games, or you end up determining that he is a no-show after the tournament has begun, you can prevent them from being considered for pairings using the “EditScore” command. If player 4 in division A should no longer be paired, enter “es a 4 0” to begin editing the player's scoresheet, then enter “off -50” give them forfeit losses whenever pairings are computed. (“off 50” will give them a 50-point bye, and “off 0” will record a missed game without assigning a win or loss). If the player subsequently returns to the tournament, you can re-enable their pairings by entering “on” while editing their scorecard.

Errors and Informational Messages

If you aren't sure what an error message means, look to see if it has a code in [square brackets] at its end. If so, use the “HUH” command to ask for an explanation. If not, contact John and ask him to add an explanation.

If All Else Fails...

My phone number is +1 416 876 7675, and I am more often in Canada’s Eastern time zone than not (UTC-4 or -5 depending on the time of year). If you arrange with me beforehand, I’ll make sure that I’m easily reachable at that number during your tournament; if not, I’ll find someone else who can be reached. If you didn’t prearrange my availability and you’re reading this because something has just gone unexpectedly wrong during a tournament, please try calling me anyway. I am also reachable when online by email, Facebook Messenger, Google Hangout and (by prearrangement) LINE, Skype or WhatsApp.

Whether or not you reach me right away, when you have an Internet connection please use the “BUGreport” command to send diagnostic information about any problems that you may encounter, so that I can fix it promptly.

Introduction to tsh

How to get started with tsh.

Overview

tsh is a program for managing a Scrabble tournament. Preferably long before the tournament begins, you need to decide the basics of how the tournament will run: how many players will play in how many separately paired divisions, how many rounds they will play, when any breaks will be, how the pairings will be determined and what prizes will be awarded. All of this information goes into an event configuration file.

As players register for your tournament, you should enter their names and pretournament ratings (if any) into the appropriate division’s data file. When you have a reasonable number, you can start running mock tournaments to make sure that you are familiar with the software and that the pairing system you have chosen works the way you want it to. If you are using cross-tables.com to keep track of registration, you can download your division data files from the director’s area on that web site. If you are using a supported rating system, you can download and use current ratings and check for membership status.

The event configuration files and the division data files belong in an event subfolder (subdirectory) of your tsh folder. You can and should use the “update” command to update your tsh folder whenever you have an Internet connection; it will not overwrite data in your event subfolders.

When all players are present or accounted for, you ask tsh for the pairings for the first round. tsh will display them on your screen and save a copy of the pairings to a printable web page. tsh saves a copy of most useful information that you’ve asked for in web pages. You may use this just for printing, or you may specify a public location for those files so that players and spectators can view the information directly. You can also tsh for a printable file containing scorecards for all players, including any pairings that have been computed.

As games finish, players submit their scores to you. You enter them into tsh, correct them if necessary, and at the appropriate time ask for the next round’s pairings. This goes on until the end of your tournament.

If you have prizes that can be automatically calculated (anything based on game scores, rather than individual plays or words), tsh will calculate them for you. If you are submitting your data for ratings purposes, tsh will prepare the data in the appropriate format.

Running tsh

This section, dealing with how to actually run tsh once you have it set up on your computer, is likely to be mostly unnecessary for most users and mystifying for many others, and is therefore addressed to those few who lie between.

Once you have installed and configured tsh, you’re ready to run tsh. Now tsh is a Perl script that runs under many different operating systems, and each operating system has a different way of starting programs. Broadly speaking, we can divide them into graphical methods and command-line methods. With the graphical methods, you need to find the icon appropriate for your operating system and (typically) double-click on it with your mouse to launch tsh, which will behave as though it was run from the command line with no “arguments”.

From the command line, you should in general enter some sort of incantation necessary to persuade your operating system to run tsh, followed by an optional “argument” giving the name of the subdirectory (folder) that contains the files for the event with which you want to work. If you do not specify an event, tsh will look first for the most recently updated configuration file it can find, or if none are available the oldstyle “tsh.config” file. Here’s what to do for some popular operating systems.

If you get a message complaining that the configuration file can’t be found, make sure that your ‘.t’ files and ‘config.tsh’ file are together in one subdirectory, of the main tsh directory.

When you successfully start tsh, you should see a sequence of messages something like the following.

Loading configuration file test/config.tsh. [iloadcfg]
Welcome to tsh version 3.200. [iwelcome]
Loading division A. [iloaddiv]
Loading division B. [iloaddiv]
Loading division C. [iloaddiv]
Event loaded: Anytown AS, 2007-12-25. [ievtname]
tsh>

The “tsh>” is your main prompt. If you have a system which supports it, the prompt will be in a distinctive colour. When you see it, you can type a command. After you type your command, don’t forget to press the return key.

Tournament Workflow

Here are the basic steps to follow in using tsh to run a tournament.

1. Use the “ROSTERS” command to generate and print a list of all your players, to check at registration time that everyone is accounted for.
2. Use the “ShowPairings” command to generate and display the next round’s pairings. For example, to show the first round pairings for Division A, enter “sp 1 a”
3. Use the “BrowseLast” command to open a browser window showing a nicely formatted version of the pairings you just created (enter: “bl”), and print it.
4. Use the “Addscore” command to begin entering game scores. Follow the link for detailed instructions, which vary according to your input options.
5. Use the “MISSING” command if you want to see which results are still missing.
6. Use the “EditScores” command to correct scores.
7. Use the “CheckRoundScores” command to prepare a list of entered scores for double-checking.
8. Use the “BrowseLast” command to open a browser window showing a nicely formatted version of the scores you just listed (enter: “bl”), and print it.
9. Use the “RATings” command to prepare a report of the current standings.
10. Use the “BrowseLast” command to open a browser window on the standings, and print them.
11. Optionally use the “STATisticS” command to update a large number of statistics, use the “Browse” command to list what's available, and print whichever you like.
12. If you’re not at the end of the tournament, and are not using Portland pairings, go back to Step 2.
13. Use the “PRiZes” command at the end of the tournament to display a list of prizewinners.

Make sure at a minimum that your data entry staff are well versed in using the commands listed above. A technically minded but untrained person should require 10–15 minutes of initial training, and a half-day's worth of supervised data entry to acquire good fluency with the program.

tsh Commands

The basics of how to operate tsh.

How to Enter Commands

tsh is a command shell. If you’re familiar with using shells such as any Unix shell, OS/X Terminal or even DOS, you can probably skip this paragraph. A command shell is a no-frills way of interacting with a computer. In a large window, the computer displays a prompt, inviting you to type in a command that the computer understands. When you do so and then press the “return” key (analogous to hitting your clock in Scrabble), the computer takes some action based on what you’ve entered, then prompts you for your next command. Sometimes your command is modal, causing the computer to prompt for and expect a different set of commands until the mode is complete.

Pay attention to the changing prompts, which indicate what information tsh needs. Don’t forget to press the “return” key to confirm each command.

If you make a mistake and want to correct a previous command, or if you just want to repeat it, you may (depending on your system configuration) be able to scroll back by using the arrow keys on your keyboard. If pressing the arrow keys instead adds garbage to your screen, you can’t, but might consider installing the appropriate Term::ReadLine module that got left out of your Perl distribution (for OS/X users it's Term::ReadLine::Perl).

If you want to enter more than one command on a line, separate them with semicolons. Each one will be executed in turn before you are returned to the main prompt.

The Most Important Commands

The most important commands to remember are “quit”, “help” and “huh”.

Quit

The “quit” command makes tsh stop running.

HELP

If you’re not sure how to use a command, then try typing “help the-name-of-the-command”. Here’s an example, showing what one version of tsh shows when you enter “help help”:

Usage: help topic

Use this command to view built-in documentation.  For fuller details, please
consult the HTML reference manual.  Enter “help index” to see a list of
available commands, and “help” followed by a command name to find out more
about that command. 

The first line tells you that when you use the “help” command you are expected to enter a topic after the word “help” so that tsh will know what you are asking for help about. Most commands require some supplementary information (called arguments) such as a division name, round number or player number.

The DOCumentation command opens a web browser to this reference documentation. If you enter “doc”, a window should appear displaying this manual’s introductory page.

HUH

If you’re not sure what a message means, and it has a code in [square brackets] after it, enter “huh the-message-code”. Again, messages are documented in this way, and soon all of them will be. If you enter “huh” on its own, the last message you saw will be explained. To take a mostly random example, if you saw the message “If you are sure you want to pair Round 12 based on Round 10, please specify config session_breaks. [eacpnsb]” you might want to know more and enter “huh eacpnsb”. You would then see the message:

[eacpnsb] It looks like you are relying on the default Chew pairing system, but
the program is not sure whether you wanted to compute pairings for the upcoming
round based on the first or second preceding round.  You can resolve the
ambiguity by setting a value for the configuration variable 'session_breaks' in
your configuration file. 

This tries to explain the original, brief message. If neither the detailed explanation nor the related documentation is clear to you, please ask John to provide further clarification.

tsh Command Reference

All currently available tsh commands are listed below in tables for reference, grouped by function. Most users will not use most of these commands. Each command has a name which verbosely describes its purpose, but which can be abbreviated to the portion shown in capital letters as shown in its example. Most commands must be followed (on the same line, before pressing “return”) by one or more arguments. These arguments are represented in examples by names, which must be replaced by actual values. If you don’t enter correct arguments, tsh will tell you what the correct ones should be, and where it stopped understanding what you were typing. Within modal commands, the syntax of what you are supposed to type varies, but is usually shown in the prompt.

To take one case, the example for the “RoundStandings” command, which displays standings in a division as of a specified round, reads rs r d. This means that “RoundStandings” can be abbreviated to its capitalised letters “rs”, and that it must be followed by a round number and a division name. You would enter “rs 5 b” and press the “return” key to ask for Division B standings as of Round 5. If you have only one division in your tournament, you may omit division names as arguments to commands. In the preceding example, you would just enter “rs 5”.

If you can’t remember a player number, you may enter enough of the player’s last and/or first names to unambiguously identify them, joined by a comma. For example, if “Chew, John” is the only player who has “HEW” in their last name, then you can see his scorecard by typing “sc hew,”. The comma is optional if you include at least two letters from one of the player’s names. As of the current release, this is not consistently implemented in modal commands such as the “Addscore” command, where the comma is not optional.

Data Entry Commands

The following commands are used for entering tournament results, as well as checking and correcting them:

Report Generation Commands

The following commands generate reports based on tournament results. You can use the “Browse” command to open your web browser to an index page showing what reports you have generated so far. The “BrowseLast” command opens your web browser to the most recent report that you requested, so that you can easily print it.

Pairing Commands

The following commands are used mainly for manually pairing rounds. You will need to know about them if you are configuring tsh before a tournament, or if you encounter an unexpected pairing situation and want to override automatic pairings. See the section on pairing theory for more detailed information about pairing systems.

The following pairing commands are deprecated, but are listed in case there is anyone who is still using them. All of these commands have been replaced by NewSwiss, which produces much better quality Swiss pairings.

Testing Commands

The following commands are used mostly for testing your tsh configuration before your tournament begins.

Miscellaneous Commands

And here all the commands which don’t fit into one of the above categories:

Plug-In Commands

There may also be external (plug-in) commands installed in your particular copy of tsh. These will be in a directory called ‘bin’, and listed in a configuration file there called ‘tshxcfg.txt’. They have been tested with OS/X (and should therefore work with most other flavours of Unix) and Windows XP, but may not work with more primitive operating systems. If not, you may still be able to use externals by running them separately from the command line. The following externals are part of the default distribution.

Utility Commands

There are also a number of standalone utilities found in the “util/” directory, which are currently provided on an as-is basis. They are ‘standalone’ in that they have to be run in a separate window from tsh. Documentation will be provided here for any command upon request.

Data Entry with tsh

How to enter tournament results using tsh.

Entering Results

tsh supports three styles of data entry, controlled by the “config entry” configuration option. The default value of the option is “'scores'”, meaning that tsh keeps track of the number of points that each player has scored in each game. Another possible value is “'spread'”, meaning that tsh keeps track only of the difference between the two players’ scores in each game. The third possible value is “'both'”, meaning that you must enter both the scores and the correct spread for each game.

You should use whatever information players enter on their score slips. If you are free to specify what this is, I recommend either scores mode or both mode. If you have staff to find players who have entered spread that does not correspond to scores, use both; if not, use scores.

Entering Scores

At the end of the round, have players or runners bring their scoreslips to you. Sort them by division, and then for each division do the following.

At NSA tournaments, bye and forfeit wins score +50, forfeit losses score −50. At ABSP tournaments, use ±75. To record that a player’s wins, losses and spread should remain unchanged, give them a bye with a spread of 0.

If you want to enter a bye, just enter one player number and one score. (In most cases, tsh will automatically enter byes for you.) If you want to switch to entering results for a different division, enter the name of the division by itself. If you want to correct a mistake in the scores that you just entered, enter “es” (see below). If you want to see which results are still missing, enter “missing” or just “m”. Whenever you want to save what you’ve entered, press the return key without entering any scores to return to the “tsh> ” prompt. You will also be returned to the “tsh> ” prompt if you enter something that tsh does not understand.

tsh saves your data every ten entries by default, or as specified by “config save_interval”.

If you have tsh set to track but not assign who went first or second in each game, you must enter game scores in player order, with the number and score of the player who went first appearing first on the line. If tsh knows who was supposed to go first (because that player had had fewer firsts than his/her opponent), then it will complain that the players determined who went first incorrectly. If it doesn’t know, it will assume that you have entered them correctly and update its information about who went first. You can use the “EditScore” command to edit whom tsh thinks went first or should go first.

There are other, much less often used data entry styles. For example, if you are running a NASPA hybrid lexicon event, you would use “'tagged'” which is like “'both'” but has you name the lexicon in effect for the game at the end after the spread; this information is stored in the “tag” extension field in player data files.

When you’re close to having all the scores in for a round, entering “missing 6 b” (e.g.) will list all the results you’re still missing for round 6 in division B. Omitting the “b” will list missing players in all divisions. You can then ask a runner or word judge to politely ask the players to pause their post mortem long enough to fill out their paperwork. As noted above, you can also just enter “m” in AddScore mode.

Checking and Correcting Results

If you make a mistake entering the score for division B player 4 in round 3, enter “es b 4 3” at the “tsh> ” prompt. You’ll get a mockup of the player’s scorecard as it currently reads, a sub-prompt that gives you that player’s score that round and their opponent’s score that round, and you can then enter one of the following commands, or press enter to return to the main “tsh>” prompt.

As indicated in the table, you can also use the “EditScore” command to make corrections to player pretournament ratings and career game totals. If you have not entered any scores yet, you may ask to edit the scores for the fictitious “Round 0” in order to run the command.

If you catch your mistake while you’re still in “Addscore” mode, you can just enter “es” (without any additional arguments) at the “Addscore” prompt. You’ll go temporarily into “EditScore” mode, looking at the data that you just entered. When you leave “EditScore” mode, you will return to “Addscore” mode.

Similarly, you can use the “LOOK” command within “Addscore” mode to adjudicate challenges.

You may wish to check what you have entered against player scorecards or against the tournament wall charts. See the section on generating reports and in particular the “CheckRoundScores” command for information on how to do this.

If you have a serious problem, you may need to edit the tournament data files directly. Pay particular attention to the information in the preceding link about how to find copies of older, journalled versions of data files. For example, if you find after entering half of the results for a round that the other half of the players used a different round’s pairings to find their opponents, you will have some careful typing to do to fix the files. (Not that this has ever happened to the author, though he has lain awake at night worrying about similar scenarios.)

As soon as you have finished entering and checking results for a round, you should prepare and print all necessary reports for the next round.

Preparing Reports with tsh

How to list standings, pairings and more using tsh.

As part of your regular workflow after you have entered scores for your tournament, you will likely want to produce and print reports such as standings and pairings tables using tsh. Each type of report is generated using its own command, and most report-generating commands display some information on your screen while saving it to an HTML file which you may print.

If you are using OS/X, you can open the documents from a second Terminal window using the “open” command. You can also print them directly to your default printer using the “lpr” command, though CSS formatting may not apply. The best way is to print from your browser.

To print the most recent report that you generated, enter the “BrowseLast” command to open the report in a new browser window, then use your browser’s print command. To print older reports, and to see which ones are available, enter the “Browse” command to open a report index in a new browser window.

By default, HTML files are created in the “html” subdirectory of your event directory. If your computer runs its own locally accessible web server (most computers can be configured to do so), then you may wish to create the HTML files directly in the server directory using “config html_directory” so that your players can check reports on their laptops or at browser kiosks that you have set up at your tournament. If you would like to have the HTML files directly in the event directory as well as in a subdirectory, you may use the “config html_in_event_directory” configuration option (this was default behaviour prior to version 3.170).

If you are using Windows, be sure to close whichever files you opened, or else tsh may not be able to update them again. (Apparently this may be an Internet Explorer bug, if you want to leave the files open, try switching to Firefox.)

The formatting of the HTML file is controlled by a CSS stylesheet called “tsh.css” If you want to copy your report files to a remote web server, you must include a copy of this file in the same directory as your report files, or they will not be displayed correctly. tsh includes master versions of the stylesheet for various realms, and if there is no stylesheet in your HTML directory, it installs a copy of the appropriate one. Once it has done so, you may make your own local changes to it if you do not care for the default style, but if you think your changes might be of general use, please send them in for inclusion in the tsh distribution.

For the sake of backward compatibility and in case tsh is run on a computer without a web browser, reports are also saved in text format. If you do not want text files to clutter your event directory, use the “config no_text_files” configuration option.

Player Photos

Some commands will display photographs to help identify players, if the “config player_photos = 1” configuration option is specified in your configuration file, and if you have one of the optional photo databases installed. These currently include: “EnhancedScoreBoard”. “ShowPairings” and “ScoreBoard”. Use the “photo_database” configuration option to choose a photo database, then keep it updated using the “updatepix” command. (This may take a while on a slow Internet connection.) Use the “player_photo_aspect_ratio” configuration option if your photos are not square. Databases are currently available for NASPA and ABSP players; tournament directors from outside those jurisdictions shoudl contact John Chew to set up their own databases.

Pairings

Before each round begins, you need to print up pairings, showing who is playing whom where. If you are using Fontes Swiss pairings, these pairings will typically be available sometime in the middle of the preceding round, as soon as you have finished entering and checking the second preceding round’s results. You should post them as quickly as possible, so that anyone who finishes their game early will know right away who their next opponent is. Using this command will also generate pages of tally slips preprinted with player information, if you want to cut and distribute them to players.

The pairings for a given division and round may have already been computed (and will be displayed right away), may need to be computed (and will be displayed after a brief delay), or may not yet be computable (and you’ll see an error message if you ask for them, instructing you to enter more scores before asking for the pairings).

You show pairings using the “ShowPairings round division” command. To list pairings (e.g.) for round 5, division C, enter the command “sp 5 c”. (If you have only one division, you may omit it, so you’d enter “sp 5”.) As noted at the beginning of this section, this will display on your screen who is playing whom where, create two printable HTML files called “C-alpha-pairings-005.html” (in alphabetical order of player name, in a two-column format if tsh thinks it will look better that way) and “C-pairings-005.html” (by player rank), and one text file called “C-pairings.doc”.

Several configuration options affect pairings reports. Their effects are described in the following table.

You may also use the “ShowManyPairings r1-r2 division” command to produce pairings reports for multiple rounds, similar to those used at the U.S. Open. This is particularly appropriate when you are pairing many rounds at a time, as for example in a round-robin tournament.

Standings and Ratings Estimates

The “RATings division” command shows current standings with estimates of new (Elo/NASPA, Elo/NASPA-LCT or ABSP depending on the values of “config rating_system” and “config division_rating_system” ) player ratings. “rat a” will tell you what Division A ratings would be if the tournament ended right now. If the previous round’s results are available when this command is used, an extra column will show who went first against whom and the game score unless “config no_show_last = 1” was specified If the next round pairings are available when this command is used, an extra column will show each player’s next opponent. Specifying “config standings_refresh” will make the HTML versions of these reports refresh themselves in the browser. You should use this command when all the scores are in for a round, and print its report. Files are created as with pairings.

You can show standings from earlier rounds using the “RoundRATings round division” command. Entering “rrat 3 c” will give you the standings as of round 3 for division C. Using the “RoundClassRATings round division” command instead will group players by class, then rank, rather than just rank.

The “tourney.pl” program can be used to produce detailed tournament reports which combine standings, estimated NASPA ratings and scores of all games. In Unix, enter “tourney.pl a.t > a.txt” or “tourney.pl -d 10 a.t > a.txt” (to split-rate after 10) to create a file called “a.txt” containing a report based on the data in “a.t”.

The now deprecated “STandings division” command does what the “RATings” command does, but without the ratings estimates, and is kept largely for use at nonrated events. Entering “st c” will give you the current standings for Division C. Files are created as with pairings. You can show standings from earlier rounds using the “RoundStandings round division” command. Entering “rs 4 d” will give you the standings as of round 4 for division D.

If you used the “classes” configuration command, then the class to which each player belongs will be shown in standings and ratings reports.

If you need more precise control over which fields (columns) are shown in the rating and standings reports discussed above, you can list the fields you want using the “rating_fields” configuration option. If you do not, the following fields will be displayed.

If you are using the “team” extension field in your “.t” file, you can use the “TeamStandings division” command to list team standings. If your teams are competing based on their aggregate performance across all divisions, you should use the “TotalTeamStandings” command.

(Deprecated) If you have a spare computer or external monitor, you can use the “hook_addscore_flush” and “hook_autopair” configuration options to automatically trigger the “ScoreBoard” command, which can show players up-to-the-minute scores and pairings information and act as a virtual replacement for paper wall charts.

The “EnhancedScoreBoard” command generates a display that is superficially similar to the now deprecated “ScoreBoard” command’s display, but differs substantially in its implementation and features. To use it, you must currently run the command once from the command line at the beginning of your event. This sets up a web page for your players, containing AJAX code that periodically fetches tournament results from your web server. (Note that to use this command, you must be serving your web pages from a web server, not just straight from your file system as is possible with many operating systems.) You should use the “hook_addscore_flush” and “hook_autopair” configuration options to trigger the “saveJSON” command, which saves a division's entire state in a form that can be read by the enhanced scoreboard. The main advantages of using the enhanced scoreboard are that there is less load on the web server, and users can browse the history of the tournament round by round, even after the event is over. You can also use it with the “setESBMeSsaGe” command to display announcements for players. Use the “config esb_geometry” configuration option to specify default numbers of rows, columns, and rank offset for each enhanced scoreboard.

Ratings Data Submission

tsh creates ratings data files in three different formats, depending on which rating system you will be submitting your data to.

NASPA Ratings

Use “config division_rating_system{'X'} = 'none'” if you have a division you do not want to submit for ratings.

There are two ways to submit ratings data to the NASPA. The much easier way is to connect to the Internet, then enter the “SUBMIT” command. In order to use this command, you must correctly set the configuration parameters “director_id”, and “tournament_id” as in the following example:

# This line gives your NASPA ID
config director_id = "CM000003"
# This line gives your NASPA tournament number
# (use the LISTT command or ask John Chew if you don't know how to get it)
config tournament_id = 123

If you cannot directly connect your tsh machine to the Internet, try running the “SUBMIT” command anyway. This will create a file called “all.tsh” in your event directory, which you may upload through the Member services section of the NASPA website.

Use the “config ratings_note” configuration option if you want to include a note about the event for the rating officer. Use the “director_name” and “event_name” configuration options to include the director’s and event’s names for the historical record.

ABSP Ratings

The “ABSPgrid” command generates a ratings grid for submission to the ABSP. The grid will be saved as a text file called “abspgrid.doc” in your event directory.

AUPAIR Ratings

The “AUPAIR” command generates a “.TOU” file in the format used by the “AUPAIR.EXE” program. The file is not displayed on the screen. “AUPAIR.EXE” is used by Bob Jackman and his WESPA Rating System, and by many countries in southeast Asia.

Prizes and Statistics

The “PRiZes” command generates a table listing all the prizes that you will be awarding, with the current leading candidate for each. To use it, you will need to add prize declarations to your configuration file, and you should print or preview a sample report after a dry run to check for completeness and correctness.

You can show standings based on a range of rounds using the “ResultsByRound firstround-lastround division” command. Entering “rbr 1-7 b” will give you the standings based on the first seven rounds for Division B. Files are created as with pairings.

The “HighWin count division”, “HighLoss count division”, “HighCombined count division”, “HighSpread count division”, “LowWin count division”, “LowLoss count division”, “LowCombined count division” and “LowSpread count division” commands list players who have excelled in each of those categories. For example, “hw 20 a” lists the top twenty game scores in division A, the rounds in which they took place, the losing score and the names of the players involved.

The “HighRoundWins roundrange division” and “HighRoundLosses roundrange division” commands list the players who have scored the highest wins or losses respectively in each round in a designated range. For example, “hrl 2-5 b” lists the high losing play in Division B in each round from Round 2 to Round 5.

The “AVErages division” commands lists average scores for all players in the given division. For example, “ave d” lists average scores for all players in division D.

The “AverageOpponentScores division” commands lists average scores for all players in the given division. For example, “aos c” lists average opponent scores for all players in division C.

The “TOTalScore division” commands lists total scores for all players in the given division. For example, “ave d” lists average scores for all players in division D.

The “STATisticS” commands lists summary statistics for each division in the tournament. For example, “stats” lists stats such as the minimum, mean, median and maximum rating in each division, the percentage of time the higher-rated or starting player won, etc. It also invokes most of the other commands in this section to update the web versions of the reports. Suggestions for additional statistics are very welcome.

There is a command for computing NASPA’s “Tuff Luck” prize based on the lowest total of six losing spreads: “tuff 6 a” lists the “Tuff Luck” standings for Division A. The opposite of this command is the “luckySTIFF” command, which lists players based on the sum of their closest winning spreads: “stiff 3 b” lists those players in Division B who have won three games by the smallest combined spread.

If you run a U.S.-style rotisserie pool, you can use the rotofile configuration option to specify the location of a text file giving the structure of that pool, then use the “ROTO” command to display current standings. Each team is represented by a list of names, followed by a blank line. The team owner’s name is preceded by the word “owner” and a space, each team member’s name is preceded by the word “player” and a space.

If you run a U.K.-style rotisserie pool, you can use the spitfile configuration option to specify the location of a text file giving the structure of that pool, then use the “SPITroast” command to display current standings. Each line in the text file consists of all the player numbers in the division in the order in which a team owner expects them to finish, a semicolon, the team owner’s name, a semicolon, and the team name. Team names must be unique.

The “COMMentary” command creates textual commentary about what happened in a given round in a division in subdirectories of the directory specified by “config commentary_directory”.

The “UPSETs” command lists the top twenty ratings upsets: games in which a significant ratings underdog managed to win. The “HighRatingChanges” command lists players whose rating has increased by the largest amount.

Checking Scorecards and Wall Charts

tsh includes commands for producing electronic versions of player scorecards and tournament wall charts. These were originally intended to allow you to check these documents and correct your data. As of 2005, the only official version of NSA/NASPA tournament results is deemed to be the data that you entered from the result slips, so these commands should be used only to point out and explain errors in the printed documents, or to replace a lost scorecard at a player’s request.

Your score checker should sort result slips in the order in which they are printed by the “CheckRoundScores” command: by winner ID if “config check_by_winner” is in effect or “config track_firsts” is not, otherwise by starting player ID.

You may wish to recheck your data entry in the middle of each round. To facilitate your doing so, the “CheckRoundScores round division” will list what has been entered for each game. Entering “crs 3 h” will list scores for Round 3 in Division H. A file called “H-scores-003.html” will be created, which can be printed and given to a checker to work offline with the result slips.

You can show a scorecard using the “ShowscoreCard division player” command. Entering “sc j 5” will give you the scorecard for player J5. A file called “J-scorecard.html” will be created, which can be printed and given to a player who has lost their original scorecard. Scorecards are also displayed whenever you use the “EditScores” command. When a score has been added to a scorecard within the last two hours, the age of that modification in minutes is shown at the top of the card. This is to help determine whether an absent player may be away taking a break from a game that ran unusually late.

You can generate an HTML file containing all scorecards for a division with the “ShowDivisionScoreCards division” command. Entering “sdsc a” will create a file called “A-scorecard.html” containing the scorecards for all players, which can be printed and given to players at the beginning of the tournament. This is particularly useful when most or all of the pairings are predetermined, as for example in a round robin schedule. Depending on the length of your tournament, you may need to edit the CSS stylesheet to make the scorecards fit nicely on each page.

You can show a wallchart using the “showWallChart division” or “showRankedWallChart division” commands. Entering “wc g” will give you the wall chart for division G. Typing a round number before the division name will start the wall chart at that round, in case your wall chart would otherwise be too wide to print nicely. Files are created as with pairings; the HTML version includes much more information than can fit into the text or screen versions.

If you need a printed list of all the players with their player numbers and ratings, use the “ROSTERS” command. By default, they'll be listed by rank, unless you specify the “config roster_order” configuration option.

Installing tsh

How to obtain and install what you need to run tsh.

What You Need

To run a tournament using tsh, you need the following:

• Perl: a cross-platform programming language
• a text editor to edit configuration files
• master sheets from which to print score slips and other forms
• the ZIP archive of the complete tsh distribution

Perl

First, you should make sure that you have a recent version of the freely available Perl interpreter installed on your machine. tsh is currently regularly tested with Perl 5.10.0 and Perl 5.14.2, should run with any version of Perl 5 beginning with 5.6, and might run with Perl 6. Perl runs under several operating systems, including but not limited to Unix, MacOS, VMS and Windows. Please follow the appropriate instructions below.

Perl for Windows

There are two popular versions of Perl for Windows: ActivePerl and Strawberry Perl. I used to recommend ActivePerl, because it came with some Perl Windows modules that tsh requires. Since 2019 though (and in Perl terms, version 5.28.0), ActiveState has made it very difficult to install those modules; and at about the same time Strawberry Perl fortuitously started including them.

If you want to use ActivePerl, you will need to create a free account to download what used to be called the community edition. Once you log in, you'll be taken to a page where you can download one of three installers. You’ll want the one that ends in “.msi”, but don’t download it yet. Go to the Overview tab and ask it to add the following modules: “Win32::API”, “Win32::Console”, “Win32::Internet”, “Win32::TieRegistry”. Then wait a half hour or so while for the webpage to think about that, then download and run that installer.

If you skipped ahead and downloaded a copy of ActivePerl without those modules, run its installer again to uninstall it. Then go back to the webpage to add those modules, and download and run a new installer.

If you want to use Strawberry Perl, just go ahead and download and run its installer.

Getting programs to run when icons are clicked is surprisingly complicated in Windows, so I have provided two batch script icons called dos64-tsh3 (for ActivePerl users) and strawberry-tsh (for Strawberry Perl users). If you end up installing your copy of Perl in a nonstandard location, you may find that neither one works, and you will have to open a DOS window manually to launch Perl.

Text Editor

You will also need a text editor. You will use it to set up config.tsh, your settings file. You may also use it to edit tournament (".t") files if you find you need to do something in the heat of a tournament that I didn’t expect you to need. If you’re a Unix user, you know which editor is the One True Editor and don’t need to be told. (It’s vim, of course.) If you’re a Classic MacOS user, SimpleText will do in a pinch, but BBEdit is much better. Mac OS/X users can use vim, vi, pico, or TextEdit, but they should not use a Classic mode editor like BBEdit unless they are careful to specify Unix line breaks. Windows users can use Notepad or Wordpad.

Forms

Score slips should be prepared to work best with tsh’s workflow. If you are entering scores and not just spread, the slips should contain the following information in the following layout:

1st player (start): 1ST-NUMBER 1ST-SCORE 1ST-NAME 1ST-INITIALS
2nd player (reply): 2ND-NUMBER 2ND-SCORE 2ND-NAME 2ND-INITIALS

The fields may be rearranged to some extent to suit layout constraints, but the important thing is that the numeric information that needs to be entered into tsh appears in the “1st-player-number, 1st-score, 2nd-player-number, 2nd-score” order in which it will be needed.

If you have configured spread-based entry, your slip should look something like this:

1st player (start): 1ST-NUMBER 1ST-NAME 1ST-INITIALS
2nd player (reply): 2ND-NUMBER 2ND-NAME 2ND-INITIALS
                    SPREAD

If you use a self-posting wall chart, it should be set up so that the player names read down the left side and the round numbers across the top. I have master sheets for stickers and score slips available for download in PDF format. You should consider instead bringing in an external monitor and using it to display an electronic scoreboard, which will give the players the same immediate feedback on current standings, while saving paper, time and effort.

tsh.zip

All of the basic files you need to use tsh, except for configuration files specific to your event, can be downloaded in one zip archive. When you have downloaded and expanded the archive, you then need to set up those configuration files. Windows users please note that the best place for you to expand your archive is a folder called “tsh” on your desktop; the worst place to expand it is anywhere in “Program Files”, where some versions of Windows may not give you permission to run tsh.

Updating tsh

tsh is a work in progress: it’s updated several times per year to include helpful suggestions from its users. Older versions are available for download from the tsh web site but are not supported. You should be sure to upgrade to the current version when you get ready to run a tournament.

If you have a copy of tsh 2.975 or later and a modern operating system (such as OS/X or some other kind of Unix, or even Windows XP), you can update your copy of tsh by simply entering the “update” command at the “tsh>” prompt. Your machine must be connected to the Internet when you enter the command for this to work, and any personal firewall must permit Perl to connect to external web sites at port 80. If you lose your connection during an update, just enter “update” again when your connection is restored.

The “update” command gives you the newest possible version of each file, which may be newer than the currently posted official ZIP archive.

If you can’t run tsh to use the “update” command, try running the “get-tsh.pl” script in your tsh folder.

If you have an older version of tsh, download the current ZIP archive, and don’t forget to copy over your event files to the newly created folder.

Extras

The main distribution described above does not a number of optional extras, which are kept separate because they are large, possibly realm-specific, and not every director may find them necessary.

Player Photos

Some commands will display photos of players when they are available. To install a photo database, set your realm or photo database in your configuration file, then use the “UPDATEPIX” command. See below for instructions about administering a tsh photo database.

Ratings

Some commands will display and update ratings for players when they are available. To download the most recent ratings from the web, set your realm or rating list in your configuration file, then use the “UPDATERATINGS” command. This stores a local copy of the full rating list for your rating system, but does not update any division data files. To update your division data files based on the most recently downloaded full rating list, use the “USERATINGS” command.

Word Adjudication

The “LOOK” command can be used for word adjudication; it currently checks the words entered in all available dictionaries. To use the command, you must first install the dictionary files using the The “UPDATE-DICT” command.

Plug-ins

Some features of limited or local interest are available only as plug-in modules. Contact the author for information about installing them.

Administering a Photo Database

tsh photo databases are stored on webservers and typically updated using an FTP client. The files in a database are all stored in one directory on the server, and possibly in its subdirectories. There are two index files which must be located in the root directory: “photos.txt” and “MANIPICS.txt”. You will edit the “photos.txt” file tells tsh which photo belongs to which player. The “MANIPICS.txt” file is automatically updated as described below and describes when each file was last changed, so that tsh knows which ones need to be downloaded.

Here is what to do whenever you make a change to your realm’s photo database: adding, deleting or renaming a photo.

1. Upload new photos to the FTP server. Photos should all be the same size (I recommend 128x128 pixels) and have the head occupying the same proportion of the photo (I recommend no more than 10% margin at top and bottom). Put them in sub-folders “a/”, “b/”, “c/”, ... to keep things tidy. Feel free to make sub-sub-folders or additional sub-folders.
2. For each photo, you need a line in the “photos.txt” file. It should have three tab-separated fields, no more, no less. If you have a player who will appear in a “*.t” file as “Chew, John”, and his photo is called (case-sensitive) “chew_john.jpg” is in the “c/” sub-folder, then his entry should read (representing tabs as <tab>)
   John<tab>Chew<tab>c/chew_john.jpg
   If you have a player who only has one name, appearing in the “*.t” file as “Winter”, and his photo called “winter.jpg” is in the “w/” sub-folder, then his entry should read
   Winter<tab><tab>w/winter.jpg
   Upload a new copy of the “photos.txt” to the server whenever you make a change to your photos.
3. Open your web browser to the page that you have been assigned that rebuilds the “MANIPICS.txt” file. The URL should end in “/cgi-bin/update-pdb.pl”
4. Finally, in each copy of tsh that you are using, make sure the config.tsh file specifies the realm or photo database and run the “UPDATEPIX” command.

Configuring tsh

How to set up tsh for your particular tournament.

After you’ve installed tsh, you need to set up a subfolder (directory) of your tsh folder containing a configuration file (“config.tsh”, formerly known as “tsh.config”) describing your tournament, and one (“.t”) data file for each division. You can run as many tournaments as you like with one installation of tsh, but each one should have its own folder.

About The “config.tsh” file

When you ask me to create your files, please e-mail me the following information: your name; your event’s name; the number of rounds in your event; the number of divisions in your event; the names, divisions and ratings of the players you expect will play, or at least an estimate as to the numbers of players in each division; the number of places to which prizes will be paid; the numbers of rounds after which breaks (for meals, snacks, or the end of a day) will be held; the pairing system you will use (I recommend Chew pairings); whether or not some number of finalists will advance to a separate final event; your game result sheet style: scores, spread or both; your board numbering style: by board or by table (which may have more than one board) or none; your board numbering sequence: restart at one in each division, or number continuously; whether you want to display player photos in scoreboards and pairings reports; whether you assign firsts (starts) and seconds (replies) or have the players determine them; whether you want to keep track of firsts/seconds (starts/replies); how many points of spread you customarily assign for a forfeit/bye: 50 or 75.

You need to have a text file called “config.tsh” in your tournament folder/directory. You can ask me (John Chew, poslfit@gmail.com) to create one for you if you give me a few weeks’ notice. There are also a few sample tournaments that come with the tsh distribution, and you can try modifying one of their configuration files to make your own.

Your configuration file consists of a sequence of lines. The order of the lines sometimes matters: you may run into trouble if you try to specify the properties of a division before you declare its existence. The first word on a line determines its type, of which there are currently eight:

• comment
• division declaration
• class declaration
• configuration option
• automatic pairing instructions
• prize declaration
• encoding directive
• Perl command

Note that the lines that appear in a configuration file are not regular tsh commands. Here is a very short sample “config.tsh” file.

# This is a comment because it starts with a '#'.
# The next line that you will store the data for Division a in file a.t.
division a a.t
# The next line says that the division has 3 prize classes
classes a 3
# The next line says that you want to keep track of 1sts/2nds (starts/replies)
config track_firsts = 1
# The next line says that Division A will play a simple round robin
autopair a 0 1 rr a
# The next line says that 1st place in Division A wins $25,000.
prize rank 1 A $25000
# The next line demonstrates the 'perl' command
perl print "Hello, world\n";

There's also an experimental configuration directive called ‘begin”, which gives a command that should be run whenever you begin working with the tournament.

The following subsections discuss each type of line in detail.

Comments

Comments begin with a ‘#’.

You may add as many comments as you like to your configuration file, and it’s a good idea to be verbose so that the next person who runs your tournament for you will know what you were thinking.

Division Declarations

Your configuration file must contain at least one division declaration, beginning with the word ‘division’, then followed by a space, a case-insensitive division name, another space, and a filename. Division declarations must come before any other reference to a division in a configuration line. Filenames may or may not be case-sensitive depending on your operating system. You may have as many divisions as you like, but each one has to have its own division name and file name. All divisions should play the same number of rounds at roughly the same schedule; if not, you should set up separate directories and configuration files for differently scheduled divisions, and run separate copies of tsh.

In a multi-division event, you should keep the division name short, as it will appear beside player numbers and you will need to type it to specify divisions. If you want a longer version of the name for display purposes, use the “config division_label” configuration option.

If you have only one division in your tournament, it does not matter what you name it, and you won’t ever have to type its name. Except: if you give your only division a name that could also be a player number, some commands may get confused if you don't type the division name, so use alphabetical division names where possible. If you have more than one division, you should keep your division names short as you will be typing them frequently.

Class Declarations

Your configuration file may contain one or more class declarations, beginning with the word ‘classes’, then followed by a space, a case-insensitive division name, another space, and an integer greater than 1. Classes are typically used to award prizes to deserving lower-ranked players in a division.

If you specify how many classes a division has, then players will be assigned to equal-sized classes according to their pretournament ranking. Classes are named ‘A’, ‘B’, ‘C’... and are listed in the ratings and standings reports. This assignment takes place each time you run tsh: if you change player ratings, it may change player classes.

You can instead manually assign players to classes in the “.t” file using the “class” extension field, which you might want to do if labelling players in a particular group for use with the gibson_class configuration option to restrict opponents of Gibsonized players to members of one class. In this case, you would append to the end of each line in the “.t” file a semicolon, then the keyword “class”, then a space, then the name of the class.

Configuration Options

There are a large number of configuration options that you can set using lines beginning with the “config” keyword. All configuration options are at least theoretically optional, because they either have reasonable default values (which may depend on your configuration realm, or not required by all commands (a notable counterexample is the “max_rounds” option, which tells tsh how many rounds long your tournament is, and which is therefore required for the proper functioning of several pairing commands.

Here are all currently available configuration options:

Option	Example	Description
account_for_h2h_sr	account_for_h2h_sr = 1	If set and firsts are being assigned, players' head-to-head record of firsts and seconds will be considered after their overall record and before the length of any runs of firsts or seconds.
addscore_prompt	addscore_prompt = 'games'	“Addscore” will prompt with number of games remaining (rather than scores).
allow_gaps	allow_gaps = 1	tsh usually assumes that each player plays their games in chronological order, round by round. If this is not the case, you can specify this option, but be warned that this will cause most pairing and report commands to fail.
alpha_pair_first_page_break	alpha_pair_first_page_break = 14	tsh will force a page break after this many rows (defaulting to the value of “config alpha_pair_page_break”) are shown on the first page of two-column alpha pairings.
alpha_pair_page_break	alpha_pair_page_break = 15	tsh will force a page break after this many rows (defaulting to 10) are shown in two-column alpha pairings. If you choose a value that is too small, then some rows may be split across pages and hard to read.
alpha_pair_single_column	alpha_pair_single_column = 1	If set, will always show alphabetic pairings in a single column, even when there are a large number of them.
assign_firsts	assign_firsts = 1	Have tsh randomly determine who goes first when players would otherwise have to draw. Sets the “config track_firsts” option if it is not already set.
autopair		Set using the autopair instruction. It’s not a good idea to mess with this directly.
auto_koth_repeats	auto_koth_repeats = 2	If set, then KOTH pairings induced by “config force_koth” have the specified number of maximum repeats, rather than an unlimited number.
avoid_sr_runs	avoid_sr_runs = 1	If set, try to avoid assigning a player too many consecutive starts (1sts) or replies (2nds) when pairing a win group. Does not currently work with round robin pairings, which are carefully arranged to make players balance in the end.
backup_directory	backup_directory = './notold/'	Override the default “./old/” as a place to keep journalled “.t” files. Must end with a “/” or other locally appropriate path separator.
board_stability	board_stability = 1	If set to 1, try to keep one of the two players in each game at the same board in the next round during sessions (if you do not specify “config session_breaks” the entire tournament is treated as a single session). If not set, boards will be reassigned each round to place high-ranked players at low-numbered boards.
bracket_cap	bracket_cap = 16	If specified, bracket_pairings will apply only to that number of top players.
bracket_noncon	bracket_order = 'nasc'	If set to nasc, players who do not advance in bracket_pairings will be paired by NASC algorithm; if none, they are left unpaired.
bracket_order	bracket_order = 'id'	If set to id, bracket_pairings will be seeded by player number; if rating, by pretournament rating.

bye_spread	bye_spread = 75	Sets the number of points of spread awarded to a player who is assigned a bye. You should probably adjust the value of “realm” rather than change this directly; contact John Chew if this is not possible. As a special case, if you set this to zero, byes count neither as wins nor losses.

If not specified, each final rank is considered to be of different value to a player. The example given should be used where the current event is a preliminary to qualify players for a two-player final match and it doesn’t matter whether a player finishes first or second. In the unlikely event that you wanted to have players ranked 3 through 6 compete in a separate final match, you could specify the value “[[1,2],[3,4,5,6]]”.
gibson_spread	gibson_spread = [250,175,150]	Overrides the default spread thresholds for Gibsonization. The nth value from the end gives the maximum spread by which a player may win a game in the nth last round; for earlier rounds, the maximum spread is given by the first value.

By default the pairings round is the last for which pairings have been entered, an optional integer parameter to the “STandings” or “RoundRATings” commands will show pairing bars for a specific round. An integer indicates the number of times players have been paired against each other prior to the round for which pairings are displayed. One or more asterisks indicates the number of times players have been paired back-to-back. This feature should be considered experimental, contact vince@wgvc.com directly with any issues.

	pairing_system = 'guelph'	Guelph pairings are used by Andy Saunders in Guelph, ON, CAN to pair six, eight or ten players in a six-round schedule.
	pairing_system = 'manual'	You should explicitly specify the use of manual pairings if you do not want tsh to provide default pairings.
	pairing_system = 'nast'	You should use NAST pairings if you are directing a satellite event of the North American Scrabble Tour, which has specific requirements for the pairings of such events. The exact system depends on the number of players in the tournament, and consists of either four rounds of fixed pairings and one round of Swiss pairings or five rounds of fixed pairings, followed by one round of KOTH pairings.
	pairing_system = 'none'	Although tsh began as a program for generating pairings and reports, it can also be used at events like crossword or Sudoku tournaments, where players compete separately to attain individual scores. No pairings are generated or displayed, but standings reports and web features are available.
pair_page_break	pair_page_break = 15	If this option is specified, tsh will force a page break after this many rows are shown in rank-ordered (not alpha) pairings. If this option is not used, player names may be split across page breaks.

player_photos	player_photos = 1	If specified, display photos of opponents in alpha pairings reports.
pname_from_sbname	pname_from_sbname = 1	If this is set to a nonzero value, the pname .t file keyword will inherit its value from sbname and this value will be used in cases where use_pname would be effective. If the use_pname config value is also set and a player's pname is defined then this value will not be overriden by their sbname.
port	port = 7777	If this is set to a nonzero value, tsh will use its web interface instead of its command-line interface. Still in early development and incomplete but feel free to see what is there so far.
prize_bands	prize_bands{'A'} = [2,3,4,5]	Specifies which final ranks are to be considered equivalent for pairings purposes: the numbers given mark the end of each band (range) of equivalent prizes (ranks). Only used in scoreboard displays and in Chew pairings, which try to pair players who are in contention for one prize band with each other. In the example, the top prize band goes from 1st place to 2nd place (presumably because the top two finalists qualify for a playoff); each of 3rd, 4th and 5th place is its own prize band (presumably awarding players cash prizes); and everything from 6th place on is the last prize band (presumably winning nothing). If this option is omitted when required, a warning is displayed and a default value is assigned which assumes prizes are assigned to the top quarter of the division. Note that Gibsonization won’t work with a value of “[1]”, because the “highest ranked player out of contention for prize money” that the Gibsonized player ought to play ends up being the second-ranked player.
prize_bands_from_prizes	prize_bands_from_prizes = 1	Indicates that the prize_bands for all divisions are to be derived from the rank prizes as specified by the prizes configuration, so that if you intend to set prize bands of the form [1,2,...N] you need only enter the number of prizes once.
prizes		Set using the “prizes” instruction. It’s not a good idea to mess with this directly.
quiet_hooks	quiet_hooks = 1	If enabled, do not display the output of commands being triggered by hooks.

Acceptable values are “'auto'” (do whatever TSH thinks is appropriate), “'forced'” (always pair the top half in order against the bottom half, disregarding things like firsts and seconds), and “'koth'” (minimize rank distance between opponents).
table_format	table_format = '%3s'	sprintf(3) description of how table numbers are formatted.
table_method	table_method = 'consecutive'	If set to “consecutive”, assigns boards to table numbers consecutively across divisions. If left unset, or set to the default value of “none”, does not assign boards to tables automatically.
table_title	table_title = "Room"	Specify what tables are called in titles. The default value is “Table”.
tables	tables{'A'} = [1,1,2,2,3,3,4,4,5,5]	List which board is at which table. Division name must be capitalized. If you don’t give information for enough boards, you’ll get cryptic error messages. You may use Perl expressions like “1..20” or “map { $_, $_ } 1..20” to save typing.
tally_slips_blanks	tally_slips_blanks = 1	If specified, the tally slips generated as a side effect of the “ShowPairings” command will include an area for designating blanks.
tally_slips_challenges	tally_slips_challenges = 1	If specified, the tally slips generated as a side effect of the “ShowPairings” command will include an area for listing challenged words.
tally_slips_no_spread	tally_slips_no_spread = 1	If specified, the tally slips generated as a side effect of the “ShowPairings” command will not include a box for spread.
tally_slips_page_break	tally_slips_page_break = 15	If this option is specified, tsh will force a page break after this many rows are shown in tally slips. If this option is not used, tally slips may be split across page breaks.
team_quotas	team_quotas = { 'AUS'=> 13, 'AUT'=> 2, 'BHR'=> 2, 'CAN'=> 9 }	Specify parameters for WSC-style quotas for team standings
terminology	terminology = 'deu'	Select the terminology that tsh uses in its reports and user interface. This feature is only partially implemented, in those areas of tsh where it has been requested. Currently supported terminology values are “absp”, “deu” and “nsa”. Contributions of additional terminology are welcome.
thai_points	thai_points = 1	If set, compute and display Thai points (2 for win, 1 for tie, 0 for loss, plus handicap) where appropriate.
tfile_encoding	tfile_encoding = 'utf8'	Specify a character encoding for ‘.t’ files other than the default ‘isolatin1’.
top_down_swiss	top_down_swiss = 1	If set, disable bidirectional optimization of Swiss pairings.
tournament_id	tournament_id = 123	Identifies the tournament for the purpose of submitting rating data.
tsh_username	tsh_username = "poslfit"	Identifies the TSH user for the purposes of accessing enhanced services.
track_firsts	track_firsts = 1	Make tsh care about who played first and second in each game. If this option is set and “assign_firsts” is not set, tsh will use the order in which scores are entered to determine who played first, and complain if the wrong player did. If this option is set and you use Chew pairings, the pairing algorithm will have a weak preference for pairing players due to go first with players due to go second.
twitter_command	twitter_command = 'ttytter -ssl -silent -status="%s"'	Specify the back-end command-line command to be used by the “TWEET” command.
twitter_command	twitter_command = 'ttytter -ssl -silent -status="%s"'	Specify the back-end command-line command to be used by the “TWEET” command.
twitter_dm_command	twitter_dm_command = 'ttytter -ssl -script -runcommand="/dm %s %s"'	Specifies the command to be used to send Twitter direct messages in the “TWeetPairings” command.
twitter_prefix	twitter_prefix = 'Live from DO:'	Specify a prefix to be attached to each message sent by the “TWEET” command.
twitter_username	twitter_username = 'whoever'	(Deprecated) Specified the username to be used to authenticate each message sent by the old version of the “TWEET” command.
unfair_byes	unfair_byes = 1	If specified, byes will always be assigned solely on standing, not taking into account how many byes each player has had. Equivalent to “config bye_method = 'always_bottom'”.
wallchart_refresh	wallchart_refresh = 30	If specified, HTML wallcharts will refresh themselves in web browsers at intervals of this many seconds.
zero_byes_tie	zero_byes_tie = 1	Specify that a bye with zero spread is to be treated as a tie, rather than a nonevent.

Configuration Realms

Because tsh is used in many different countries with many different Scrabble traditions (and it’s even sometimes used for non-Scrabble events), tsh has a quick way of specifying common default values for configuration options that vary from country to country: the “realm” configuration option. The following table shows which default values are set according to the value of this option.

Realm	Default Values Specified for Configuration Options
config realm = 'nsa' (This is the default realm.)	alpha_pair_page_break = 10 rating_list = 'nsa' rating_system = 'nsa2008'
config realm = 'absp'	alpha_pair_page_break = 10000 assign_firsts = 1 avoid_sr_runs = 1 bye_firsts = 'ignore' bye_spread = 75 currency_symbol = '£' html_in_event_directory = 1 no_index_tally_slips = 1 photo_database = 'centrestar' rating_list = 'absp' rating_system = 'absp' surname_last = 1 table_method = 'consecutive' terminology = 'absp' track_firsts = 1

config realm = 'wespa'	bye_spread = 100 rating_list = 'wespa' rating_system = 'wespa'

Configuring Pairings

tsh has a number of pairings commands, each of which adds one or more rounds of who-plays-whom information to the player data (“.t”) files. Pairing information must be entered before scoring information: the score entry command will not accept scores for players whose opponents are not yet known to the program. You should be familiar with the contents of the section on pairing theory and have decided on one or more of the pairing systems described in that section for your tournament before reading further.

There are four ways of telling tsh what kind of pairings to use: default, automatic, custom and manual pairings.

Default Pairings

With default pairings the only thing you need to tell tsh is how many rounds your tournament is:

# The following config.tsh line says that this tournament has 12 rounds.
config max_rounds = 12

After you enter the results for each round, ask tsh for the next round’s pairings using the “ShowPairings” command and it will compute Chew pairings. (If the number of rounds is large compared to the number of players, one or more round robins will be scheduled first.) The following configuration options can be set to control how these default pairings work. See the detailed description of configuration options for their syntax.

Option	Effect	Utility
auto_koth_repeats	If set, any final KOTH pairings induced by “config force_koth” will have the specified number of repeats, rather than an unlimited number.	Sometimes used in South Africa for the sake of tradition.
avoid_sr_runs	If set, minimise consecutive starts (1sts) or replies (2nds) when pairing a win group.	You might use this, if your players are likely to complain about long runs of starts or replies, and you don't mind slowing down the pairings a little.
flight_cap	If set, overrides the cap on the size of the top flight.	Do not use, unless you are a pairings wizard.
gibson_class	If set, restricts opponents of Gibsonized players to one named class.	You might use this, some but not all of your players are competing in this tournament to qualify for something else, and should not be penalized in their qualification attempt by having to play a Gibsonized opponent.
gibson_groups	Indicates final ranks that are to be considered equivalent when testing for Gibsonization.	You should only use this if you are a pairings wizard.
gibson_spread	Overrides default spread thresholds for Gibsonization.	You should only use this in consultation with your governing rules body.
force_koth	If set, the last round will be KOTH even when default pairings are being used.	You might want to use this, if your (likely North American players) will rebel at the thought of a tournament that doesn’t end in a KOTH.
initial_snaked	If set, and “InitFontes” is invoked to generate first-round pairings, players are assigned to pairings groups in boustrophedonic order rather than randomly.	Use this if you mistakenly believe that is a good thing to allow players to engineer their first-round pairings in a high stakes tournament by sacrificing pretournament ratings points, or that ratings are sufficiently accurate for detailed seeding of players.
initial_schedule	If set, specifies a number of initial rounds that will be paired in a fixed schedule.	It’s not a bad idea to set this if you have the number of players is much larger than the number of rounds, or if you want to give yourself some breathing space early in your tournament.
interleave_rr	If set, players in a multiple round robin play each opponent in turn, rather than each opponent repeatedly before moving on to the next.	This option is not set by default, because tournaments run much faster when players don’t have to move from round to round. Some players get bored playing the same opponent repeatedly though, which is why we have this option.
max_rounds	Specifies the length of the tournament in rounds.	Required.
no_initial_rr	If set, there will be no initial round robin phase, even if there are enough rounds to accommodate one.	Used in large tournaments including players with widely ranging skill levels.
pairing_system	Explicitly set to indicate which of 'auto', 'chew', 'manual' or 'nast' pairings you want.	Required when using NAST pairings, optional otherwise.
prize_bands	Should be set to indicate which final ranks are equivalent. If you do not set it, you will be warned that you have not set it each time pairings are calculated.	Strongly advised.
random_rr_order	If set, the top seed in a round robin is paired against randomly ordered opponents; if not set, the top seed faces opposition of increasing strength.	Used in Ireland, and useful in reducing data input errors in multi-division events.
session_breaks	If set, pairings may be calculated based Fontes-style on the second preceding round’s scores during sessions. If not set, pairings will only be calculated once the immediately preceding round’s scores have all been entered.	Strongly advised.
top_down_swiss	If set, disable bidirectional optimization of Swiss pairings.	Use where strict Swiss pairings are required.

Automatic Pairings

If you prefer to have more control over your tournament’s pairings, or have advertised the use of a specific system that is not the tsh default, you should use automatic pairings. This involves pre-entering all the pairings commands that you expect to use into the configuration file, where they will be automatically triggered when the time is right.

Each auto-pairing configuration line consists of the command word “autopair”, a division name, the number of the round whose results must all be in before pairings can be calculated, the number of the round whose pairings will be calculated, and then a tsh command that generates the pairings.

For example, you can tell tsh that the first seven rounds of your two-division event is a round-robin, and the eighth round is a king-of-the-hill (KOTH):

# When Div. A has no scores and needs Rd. 1 pairings: RoundRobin A
autopair a 0 1 rr a
# When Div. B has no scores and needs Rd. 1 pairings: RoundRobin B
autopair b 0 1 rr b
# When Div. A has Rd. 7 scores and needs Rd. 8 pairings: 
# KOTH with one repeat allowed based on Rd. 7 standings, Division A
autopair a 7 8 koth 1 7 a
# When Div. B has Rd. 7 scores and needs Rd. 8 pairings: 
# KOTH with one repeat allowed based on Rd. 7 standings, Division B
autopair b 7 8 koth 1 7 b

When you ask for the first round’s pairings tsh will compute the round-robin, then later on when you have entered scores for the first seven rounds you can ask tsh for the eight round’s pairings and it will compute the KOTH. If you ask for Round 8 pairings before all results are in for Round 7, tsh will remind you that it can’t compute them yet.

Here’s a slightly more complicated example, for a six-round two-division tournament where the first three rounds are paired using the “InitFontes” command, the next two are paired Swiss based on Round 3 standings but with no repeats, and the last is a KOTH based on Round 5 standings with repeats permitted:

autopair a 0 1 if 3 a
autopair a 3 4 ns 0 3 a
autopair a 3 5 ns 0 3 a
autopair a 5 6 koth 1 5 a
autopair b 0 1 if 3 b
autopair b 3 4 ns 0 3 b
autopair b 3 5 ns 0 3 b
autopair b 5 6 koth 1 5 b

As explained in the section on manual pairings, you might still need to resort to manual pairings even when you have planned on using automatic pairings.

Custom Pairings

Some directors have developed regionally popular idiosyncratic pairing systems. For example, you might have a few rounds paired according to a fixed schedule, a few rounds of Swiss, and a few rounds of KOTH. You can select one of these by specifying a value for the “pairing_system” configuration option. The “ShowPairings” command will then generate pairings appropriate to the specified custom pairing system.

To add a new custom pairing system to tsh, please submit your request at least 1-2 months before its first planned use.

Manual Pairings

You should use manual pairings if you do not know in advance exactly how you will be pairing the tournament, such as when you haven’t decided when to start allowing repeats.

You might also find during your tournament that the automatic system you specified is impossible. For example, you might have asked for a round-robin followed by a KOTH with no repeats. You can quit tsh, edit the automatic pairing instructions and then try again, but if you’re under time pressure you’ll likely prefer to just enter the pairings commands directly and manually.

Prize Declarations

The “PRiZes” command lists all the prizes you are awarding, and if it can be automatically determined, who won them. If you want to use this command, you need to list your prizes in your configuration file using the “prize” instruction. You need one instruction in the file for each prize you are awarding. For example, if you are awarding a high game prize in each of four divisions, it will take four instructions to describe them. Unlike with most other lines in your configuration file, the order in which you enter prize instructions is important, as that is the order in which they will appear in the subsequent report.

Here are some examples of actual prize instructions from recent events:

prize note Place Prizes
prize rank 1 1 $25000
prize rank 2 1 $10000
prize separator
prize note Miscellaneous Automatically Calculated Prizes
prize tuffluck 1 1 $50
prize rank 1 1 $200 groupname='55+ Senior' members=[2,5,6,21,22,23,28,30,42,46,51,52,53,68,69,72,74,78,82,85,91,101,102]
prize brlh 1 1 $200 first=15 last=21 prizename='Division 1 Best Record Day 3 Lower Half'
prize highroundwin 1 1 $20 round=1
prize highroundloss 1 1 $20 round=28
prize lowwin 1 1 $20
prize separator
prize note Signup Prizes
prize signup 'Division 1 Biggest Comeback' 1 $75
# the following line awards a trophy to the top ranked player in division 4 class N
prize rank 1 4 Trophy groupname='Newcomers' class=N prizename="Newcomers Trophy"

Each line has several items, separated by one or more spaces. If an item has a space in it, such as “'Division 1 Biggest Comeback'”, enclose it in matching single or double quotes.

1. The first item has to be the word “prize”, to identify the line as a prize declaration.
2. The second item is the prize type: a complete list can be found below.
3. The third item is the prize subtype: usually the rank a player has to attain in the category determined by the prize type in order to win the prize. In the example above, first place wins $25,000 and second place wins $10,000. Negative ranks count from the bottom of the field.
4. The fourth item is the name of the division to which the player must belong in order to qualify for the prize. In the example above, all prizes are in Division 1.
5. The fifth item is the amount of the prize. This may be a cash value, or a description of merchandise.

In addition to these five items, you may have extra items consisting of an item label, an equals sign, and an item value. A complete list of these can also be found below.

Here is a list of all currently defined prize types. If you want to compute a prize that is not listed below, please ask and it will be added.

Prize Type	Description
brlh	Computes the U.S. NSC's "Best Record Lower Half". Requires two extra items: “first” and “last”. Ranks players according to their record in the range of rounds that these specify, excluding any players who either did not play any games in that range, or began the range ranked in the upper half of the field.
highloss	Ranks players according to the highest-scoring loss they recorded.
highratingchange	Ranks players according to their rating changes.
highroundloss	Requires one extra item: “round”. Ranks players according to the highest-scoring loss they recorded in the designated round (or hyphen-separated range of rounds).
highroundwin	Requires one extra item: “round”. Ranks players according to the highest-scoring win they recorded in the designated round (or hyphen-separated range of rounds).
highwin	Ranks players according to the highest-scoring win they recorded.
lowwin	Ranks players according to the lowest-scoring win they recorded.
luckystiff	Ranks players according to their lucky stiffness (smallest margin by which they won six games).
note	Adds a note to the prize table.
overseed	Ranks players according to how high they climbed from their original rating-based seed.
rank	Ranks players according to their wins, losses and cumulative spread.
roundrecord	Ranks players according to their wins, losses and cumulative spread over a range of rounds specified by “first” and “last”.
separator	Leaves a blank line in the prize table; other arguments are ignored and may be omitted.
totalteam	Ranks teams according to the average record of their members in all divisions. See “config minimum_prize_team”
tuffluck	Ranks players according to the sum of the spreads of their six closest losses.
upset	Ranks players according to the difference between their rating and the rating of the highest stronger player whom they were able to defeat. Unlike the a UPSETs command, this version does not consider occasions when an unrated player defeats a higher-rated one.

Here is a table of extra items that may be added to any prize declaration to refine the way prizes are awarded. Each must be followed by an “=” and a value. There must not be spaces before or after the “=”. If the value includes spaces, the entire value must be enclosed in “'”.

Label	Description
class	The value assigned should be a class name. If this extra item is used, it restricts prize eligibility to players belonging to the designated class.
exclusive	If a value is assigned to this item, it designates an exclusive prize category. A player may win at most one prize from any one exclusive prize category. If they are eligible for two prizes, they will be awarded the first one listed, and the second prize will go to the next contender. If you are using this to award class prizes, list your prizes in decreasing order of value, with class prizes ahead of place prizes of equal value. You may also wish to specify “config show_honourable_mention” to list the additional prizes that a player would have won had exclusivity not been in effect.
first	Specifies the first in a range of rounds for the “brlh” and “roundrecord” prize types.
groupname	If a value is assigned to this item, the default name for this prize will display it between the division name and the prize name.
last	Specifies the last in a range of rounds for the “brlh” and “roundrecord” prize types.
memberfile	The value assigned should be the name of a file which lists player names, exactly as they appear in data files. If this extra item is used, it restricts prize eligibility to the designated players, who might be of a particular age group or from a particular country.
members	The value assigned should be a comma-separated list of player IDs, enclosed in [square brackets]. If this extra item is used, it restricts prize eligibility to the designated players, who might be of a particular age group or from a particular country.

Encoding Directives

If you need to have text in your configuration file that is not in the ISO 8859-1 (Latin) character encoding, use the “encoding” directive to specify an alternate encoding. The new encoding should be named in the directive following white space, and takes effect immediately. If you have no idea what this is about, be thankful.

Raw Perl Commands

Experienced thrill-seekers may also add lines to the “config.tsh” file which begin with the keyword “perl”. This is about as safe as using the tsh shell command “eval”, and does the same thing: it evaluates its argument as a string. There is currently no good reason for using this feature.

The “.t” Files

A “.t” file contains all the information for a division, and must be in the same subdirectory as your “config.tsh” file. It’s a text file that can be edited with a text editor if need be, and is usually created in the first place using a text editor. You may have received “.t” files for your tournament with your tsh distribution, but you should be familiar with the content of this section in case of no-shows and walk-ins.

There is an experimental script for importing data from TourneyMan files. It’s called “parsetm”, is found in the “util/” directory and can be invoked from the command-line to turn one “.ltm” file at a time into a “.t” file. It has been thoroughly tested on the version of TourneyMan to be used at the 2005 US NSC.

A “.t” file should contain one line per player. The line should look something like this:

Chew, John   1850 400 450 350; 10 4 3; p12 1 2 2; board 1 1 3

In this example, a player named John Chew entered the tournament with a rating of 1850. In round 1, he played player #10 and scored 400 points. In round 2, he played player #4 and scored 450 points. In round 3, he played player #3 and scored 350 points. He went first in round 1 and second in rounds 2 and 3. He played at board #1 in rounds 1 and 2, and at board #3 in round 3. Anywhere where there is a space on the line, tsh will tolerate as many spaces as you like, but please do not use tabs. Of course, adding spaces within a player’s name will make many reports look odd.

Scores and opponent numbers may have the special value “00”, indicating that the value has not yet been assigned. This should not be confused with the “0” that indicates a bye.

Players must be listed in order of player number, beginning with player number 1. Note that this means that players must be numbered within each division starting at 1. Unless you feel strongly otherwise, you should number players beginning with the highest-rated. If you want to number players in two divisions in one numbering system without restarting from 1 at the top of the second division, you must call the two divisions one division for data entry purposes.

When you first set up a tournament file, it will probably contain only player names and ratings. So your file will look something like:

Chew, John          1850 
Saint John, Sherrie 1300 
Chew, Kristen       1200 

Player names may include any characters other than semicolons, and must not end in a digit. If you will be submitting your tournament results to a rating system, then you should spell your player names exactly the way that they appear in official rating lists. If you really have to have a player name that ends in a digit (it has happened), put a comma after the final digit and the comma will be silently omitted in reports. Player names should be entered as shown above, with the surname (last name) first followed by a comma. If you do not do so, a few commands which need to know how to split names into given names (first names) and surnames will not function.

Not all files contain the same information for players. Some information only appears if some optional features are enabled. Each set of optional data is preceded by a semicolon and an identifying keyword. At present, the following extensions are in use:

Keyword	Data
board	Lists at which board the player played in each round. This is typically set by the “ShowPairings” command the first time pairings for the round are shown, and not changed thereafter.
class	If present, should be followed by a single-word class name: typically ‘A’, ‘B’.... Will be set automatically by the “classes” configuration command, overriding any previously set values. Is used by report generation commands to indicate which class a player belongs to.
cume	Is present if the player’s cume must be set to a given value. It should be used with extreme caution, as it will override the regular calculation of cume in all rounds. This feature is not yet fully implemented.
cumeadj	Is present if the player’s cume must be adjusted, typically to compensate for a misadjudication. It should be followed by one or two values, the first the amount of the adjustment, the second the round in which the adjustment should first be applied. This feature is not yet fully implemented.
initrec	If set, specifies an initial record of wins, losses, spread, capped spread or score sum with which the player is understood to have begun the event.
lifeg	If set, indicates the number of games that the player has played in his life, used for ratings computations. If not set, a value of 50 is assumed.
off	Is present if the player is inactive for pairing purposes. It is followed by a single integer, indicating what spread ought to be awarded to them for each missed game. This feature is not yet fully implemented.
initrec	If present, specifies a record (e.g. “5 2 1000 800” for a player who had 5 wins, 2 losses, +1000 spread and +800 capped spread) that a player is credited with at the start of the event.
p12	Lists whether the player went first (1) or second (2) in each round. Rounds where the player went neither first nor second are marked 0, rounds where the player is paired but has to randomly determine whether or not s/he goes first are marked 3, rounds where tsh is not sure who will go first or even whether a random determination will be required are marked 4.
pname	Specifies how a player’s name should be displayed in reports, possibly using Unicode characters not available at the console. You may need to specify a tfile_encoding to use certain characters.
password	Specifies a player’s password for self-service scoring.
sbname	Specifies how a player’s name should be displayed by the “EnhancedScoreBoard” command. You may need to specify a tfile_encoding to use certain characters.
seat	Specifies a player’s seat for realms where seats are numbered instead of boards.
tag	Tags a game with a user-specific label, used by NASPA for identifying game lexicon in hybrid CSW-TWL events.
team	Names the player’s team, for use in team tournaments. The value is a case-sensitive sequence of words; each instance of white space is collapsed to a single space.
twitter	Gives the player’s Twitter handle, which will replace their name in tweets issued by the “TWEET” command.

If you have an Internet connection, you can update the tournament ratings in your player data files at any time using first the “UPDATERATINGS” command and then the “USERATINGS” command. This command is not available for all realms. If it doesn't work in yours, please ask for rating support to be added.

“.tsh” Archive Files

The “BUGreport” and “SUBMIT” commands generates (and depending on configuration may upload) an archive file which concatenates the configuration file with copies of each division data file wrapped between marker lines. Here’s a very simple example.

config event_name = "Sample Event"
config max_rounds = 2
division A a.t
division B b.t
#begin_file name=a.t
Chew, John    1800 2 2 ; 400 350
Chew, Kristen 1400 1 1 ; 350 400
#end_file name=a.t
#begin_file name=b.t
Chew, Jamie 1000 2 2 ; 400 350
Chew, Liam   500 1 1 ; 350 400
#end_file name=b.t

You may use this as an archive format for past events. tsh will accept an archive name as a command-line argument, but treats its data as read-only.

User Profile

If you find yourself running a lot of similarly configured events and want to save the common configuration instructions in one place, you can do so in your user profile using the “PROFILE” command. This command lets you manipulate a file called “lib/profile.tsh” that is currently identical in format to your “config.tsh” files, but is not intended to be edited directly.

A good value to store in your profile is configuration realm.

Dry Run

Once you have everything set up, preferably a few days before your tournament, you should try a dry run of your event. The easiest way to do this is to use the “DRYrun” command, which runs an entire tournament for one division on random data using the pairings you configured. After you’ve looked at all the reports it has generated, use the “RESETEVERYTHING” command to delete all the test data.

If you want finer control over the dry run, you can do what it does manually using the “ShowPairings” and “RANDomscores” commands.

There are also a number of unsupported scripts in the “util/” folder which do further analysis on dry runs, for the purposes of compiling statistics on pairing systems and predicting event winners.

Backups and Redundancy

Now is a good time to think about what to do if disaster strikes. You should always bring an extra computer, extra printer and extra ink cartridges. If you are running a multidivision tournament and have extra staff, then you can use the extra equipment to split the data entry task across two installations of tsh, combining the two if some of your hardware fails.

tsh journals a copy of every “.t” file after every change, which is useful for correcting errors, but not helpful if your hard disk crashes or your computer dies. Follow the standard rule for backups: make a copy of important files often enough that you don’t mind having to type in any changes since your last backup. For “.t” files, this should be somewhere between every round (to be safe) and every session (to live dangerously). Back up files to other computers, the net, and/or removable media.

If your computer fails and you do not have a spare computer, announce what has happened, gather scorecards and any qualified directors and do pairings by hand. Then write out “I will not run a tournament without a spare computer” enough times by hand that you learn your lesson.

If your printer fails or you run out of ink, in a small tournament you can probably write out or announce pairings aloud, especially if you just need to cover until you can find a replacement cartridge.

tsh GUI Notes

Development notes on the experimental GUI.

An experimental version of the tsh GUI first shipped with version 3.190. This file documents the GUI, and will be entitled Notes to remind the reader of the experimental status of the module until it is ready for formal release.

Overview

The tsh graphical user interface (GUI) is implemented by having tsh run a lightweight web server on a nonstandard port. If the host machine supports it, the classic command-line interface (CLI) may be run simultaneously with the GUI.

Requirements

The experimental code is tested regularly under OS/X 10.4 and Windows XP. It is not guaranteed to work at all under other operating systems.

Earlier versions of Perl 5.8 did not return the correct value from threads::shared::share(). 5.8.6 works, 5.8.0 does not. Always use the latest greatest version of Perl. (Of course, versions of Perl prior to 5.8 did not support the current threads library at all, and don’t have a hope of running the threaded code.)

Configuration

To enable the GUI, add the line “config port = 7777” to your event’s ‘config.tsh’ file, where the value 7777 may be changed to any convenient value between 1024 and 65535.

To enable multithreaded operation, that is, simultaneous operation of the CLI and GUI, create a file called ‘threads.txt’ in the ‘lib’ directory. Yes, I know this is a hack, but it’s set up this way because enabling threading induces potential instability in the software (because of ridiculous restrictions on thread-shared data in the current release of the Perl threads library, which itself is not a mature product). I want to make sure that a user does not accidentally turn on multithreading until I’m 100% sure that the code won’t is sound. Another problem is that the way the code is written right now, and the way threads work in the current version of Perl, the obvious solution (a line in ‘config.tsh’) doesn’ work because by the time the configuration file is being read, it’s too late to activate multithreading (because the configuration file data itself would need to have been labelled as thread-shared).

If you’re successful, then when you run tsh, your CLI should appear briefly, then be superseded by a browser window showing something like a wall chart. If you’re running multithreaded, you can work alternately in the CLI and GUI windows.

Using the GUI

It’s just a proof-of-concept right now, and I don’t like the way any of it looks or functions. I’ll be reworking it over the next few months, at which point suggestions will be welcome.

Reconnecting to the GUI

If you close your browser window, you can reconnect to the GUI either by remembering the URL – ‘http://localhost:7777’ (if you chose 7777 as your port number), or looking for the URL in your browser history. If you have the CLI running too, you may use the “GUI” command to open a browser window to the GUI.

Shutting down the GUI

If you have the CLI running, quitting the CLI should shut down the GUI. Actually, there's a bug in the current version that prevents it from doing so under Windows, so press Control-C to kill the tsh process.

If not, you'll just have to press Control-C for now. Eventually there will be a button in the GUI to shut down the server.

Pairing Theory and tsh

Some background on how pairing systems work.

This section discusses the theory behind scheduling pairings for tournaments and the details of the pairing systems implemented in tsh. See elsewhere the table of tsh’s pairing commands, and the discussion of how and when to use them.

Goals

The following are desirable properties of a pairing system. It is impossible to satisfy all of these properties simultaneously.

Property	Description
“Aristomachy”	Top players should be paired with each other, especially toward the end of the tournament. King-of-the-Hill pairings do this best, Round Robin pairings do this worst.
Division Sizing	Some pairing systems (notably round robin) require specific numbers of players. The number of players is usually not under the director’s control, though often their assignment to divisions is. A small number of large divisions permits smaller number of larger prizes but requires players to face opponents of more widely ranging ratings.
“Exagony”	Players travelling together to a tournament do not like to play each other, as many players travel to vary their opponents. At the World Championships, unnecessarily pairing together players from the same country may make it difficult for them to earn an additional place at the next WSC.
Fairness	The final ranking of players by the customary win-loss record and cumulative spread should be equivalent to a ranking according to their level of performance in the tournament. Three possible ways of measuring the latter are to average the final rankings of the opponents of each player (Average Opponent Ranking or AOR, to add the number of wins and spread of the opponents of each players (Sum of Opponent Scores, SOS or Buchholz), and uninitialised iterated performance ratings (IPR, the ratings that players would have if they had all arrived at the tournament unrated).
Implementability	A good human director can pair 50–100 players by hand if a dynamic pairing system is not too computationally demanding. Computers can currently do brute-force exhaustive searches for optimal pairings up to groups of about 16 (for which there are 2,027,025 possible pairings), use smarter algorithms for very difficult pairing situations involving twice as many players, and can easily apply complex rules to larger groups to find pairings which match well-designed criteria.
Incentivization	A player should not be placed in a position where tieing or losing is strategically preferably to winning. For example, a player who has clinched a place in a two-player final should not be paired with a possibly weak player whose victory would send him to the finals.
Inclusivity	A player should not needlessly be excluded from contention for a prize by being paired with someone who is out of contention. For example, if with one round left to play the top three players have N, N and N–1 wins and the top two have a 500-point spread advantage over #3, then #3 needs to play #1 or #2 in order to have any reasonable chance of finishing first.
“Monagony”	Players should play each other as few times as possible. Repeat pairings can prevent other players from catching up to the repeaters, and do not accurately measure the repeating players’ ability to defeat a wider field. Players also do not in general like playing each other in consecutive rounds.
Monotony	A lower-ranked player should not be paired so as to make it more likely that he will become the overall winner than that a higher-ranked player will.
Suspense	The outcome of the tournament should be determined as late as possible.

Gibsonization

David Gibson, the all-time top money winner in the history of Scrabble, has made a habit of clinching victory in major events without waiting for the final round. Because of this, players are said to be “Gibsonized” when after clinching, they are paired with lower-ranked players to avoid affecting the ranking of runners-up. tsh has two mechanisms for detecting Gibson situations.

Use “config prize_bands” to tell tsh how far down you’re paying out prizes. If you omit it when it’s needed, tsh assumes you're giving prizes to the top quarter of the field.

The Chew pairing system automatically detects and assign Gibson pairings. Gibson situations are detected based on wins and generalised NASPA spread thresholds (a player may hope to win one game by 250 points, two games by an average of 175 points, and more games by an average of 150 points each, or as overridden by the “gibson_spread” configuration option). If there is more than one Gibson, as many of them as possible (all of them if the total number is even) are paired with each other KOTH minimizing rematches and consecutive rematches. If all players are still in contention for some sort of prize, it will pair any remaining Gibson with the lowest ranked player who has played him/her least often. If some players are out of contention for any prize, it will pair any remaining Gibson with the highest ranked such player who has played him/her least often.

If you have a two-player final, you may want to allow the Gibsonization of a player who has clinched a place in the top two, though not necessarily the top place. If so, use the “config gibson_groups” configuration option.

If you specify “config gibson = 1” in your configuration file, tsh will also perform Gibsonization when using KOTH or Swiss pairings.

It is important to note that if you are using Fontes pairings, a Gibson situation may develop in round n, paired based on round n–2, as a result of games played in round n–1. tsh does not currently check for this situation, and in practice the players involved might already even have started playing round n before anyone notices what has happened. If you do find yourself in this situation, try to manually repair the top few boards, if they have not already started their games. If no one has started a game, use the UnPairRound command to remove your previously calculated pairings, use the PAIR command to manually pair the Gibson with a reasonable victim, then recompute the pairings for the rest of the division.

Pairing Systems

tsh currently supports the following pairing systems, in order of increasing sophistication. If you have a need for a different pairing system, please contact John Chew at least two months in advance of your tournament.

• None
• Random
• Manual
• King-of-the-Hill (KOTH)
• Quartiles
• Factored (FP)
• Round Robin (RR)
• Lower Round Robins (LRR)
• Team Round Robins (TRR)
• Bracket
• Double Elimination
• Green
• Guelph
• NAST
• BASD
• Swiss
• Chew

No Pairings

Although tsh began as a program for generating pairings and reports, it can also be used at events like crossword or Sudoku tournaments, where players compete separately to attain individual scores. If you specify “config pairing_system = 'none', all players effectively receive unscored byes, and after you enter their scores you can view standings reports.

Random Pairings

Random pairings match players based on a statistical hashing function of their name and player number. They are random in that who plays whom will not appear to follow any pattern, but only pseudorandom in the sense that if you do not change the names and order of your players the pairings will always be generated the same way.

You might want to use random pairings when assigning first-round pairings for a group of players who do not have a reliable past tournament record.

The general command for random pairings in tsh is “randompair repeats based-on-round division”. For example, to ask for random pairings with no repeats allowed, based on standings in round 7 for division D, use the command “rp 0 7 d”. This example is somewhat contrived though, as after the first round it would be foolish to use random pairings rather than some sort of standings-based pairings.

See also the “config initial_exagony” configuration variable for avoiding pairing players from the same team in the first round. If you use this variable and do not assign players to teams, pairings will fail because everyone will appear to belong to the same unnamed team.

As it does with other pairing commands, tsh will try to minimize repeats and avoid successive repeats where possible, though in the first round this is irrelevant.

Manual Pairings

Sometimes, you can’t use a computer to do all your pairings. For theatrical purposes you might have the first round’s pairings be done by a physical draw. You might need to tweak computer pairings because someone has taken ill after you’ve computed your pairings and some people have started to play. You might want to manually pair a few players and allow the rest to be automatically paired. Or something really weird and unexpected might have happened.

tsh provides two commands for manual pairings. If you’re just doing a few, then use “PAIR p1 p2 round division”. For example, “pair 1 2 5 a” pairs players 1 and 2 in round 5 in Division A. To assign a player a bye, pair them against the fictitious player 0.

If you need to do a lot of pairings, use the “PairMany round division” command. For example, “pm 3 b” lets you enter pairings for round 3, division B and prompts you to enter pairs of player numbers, one pair per line. If you enter a division name by itself, you will switch to entering pairings for that division. If you enter a round number preceded by an R and a space, e.g. “r 5” you will switch to entering pairings for that round. If you enter anything else, you will return to the main prompt.

You cannot assign pairings for a round until all previous pairings for both players have been assigned, and tsh will stop you if you try. You can reassign pairings for players who have already recorded scores, but should do so only with extreme caution, and you will likely need to use the “EditScores” or “DELETEscore” command. Use the “ShowPairings” command to check your pairings after any manual changes, to make sure that all players are paired and none are multiply paired (tsh will warn you of either situation).

If you want to pair partially manually and partially automatically, remember that tsh invokes its automatic and default pairing mechanisms when you use the “ShowPairings” command. Specify any manual pairings before using that command. If you forget and do a “ShowPairings” first, then use the “UnPairRound” command to un-pair all of the last round’s pairings from a division.

King-of-the-Hill Pairings

In King-of-the-Hill (KOTH) pairings, the top two players are paired with each other, then the next two, and so on.

KOTH pairings are often used in the final round(s) of a tournament to ensure that contenders face each other, often with an extra repeat permitted so that contenders face each other again even when they have already played each other.

The general command for KOTH pairings in tsh is “koth repeats based-on-round division”. For example, to ask for KOTH with one repeat allowed, based on standings in round 11 for division B, use the command “koth 1 11 b”.

If the players who are supposed to play each other have already played each other too often, tsh will look for the nearest available player, breaking ties to avoid consecutive repeats, match starts with replies and minimize repeats. If the number of players is odd, tsh will assign a bye to the lowest-ranked player who has had the fewest byes.

Quartile Pairings

Quartile pairings pair the top quartile of the field at random against a designated other quartile, and are typically used to begin large tournaments with unreliable rating data, such as the World Scrabble Championship.

The general command for quartile pairings in tsh is “PairQuartiles quartile repeats based-on-round division”. For example, to ask for the top quartile to be paired with the bottom, with no repeats allowed, based on standings in round 12 for division B, use the command “pq 4 0 12 b”.

Factored Pairings

Factored Pairings (FP) are the same as KOTH except that the optimum rank separation of players is some fixed number (the factor) greater than the value of one used in KOTH.

A version of FP is used in the (US) NSC in preliminary rounds, with factors gradually decreasing from 20 to 2, to artificially control the rate at which the contender pool shrinks. (At the NSC, pairing is done in groups of four to eight players, three or four rounds at a time.)

The general command for FP in tsh is “FactorPair distance repeats based-on-round division”. For example, to ask for FP(2) with no repeats allowed, based on standings in round 14 for division C, use the command “fp 2 0 14 c”. The “Pair1324” command is a synonym for “fp 2”.

If the players who are supposed to play each other have already played each other too often, tsh will look for the nearest available player(s) to the optimum opponent(s), breaking ties to avoid consecutive repeats, match starts with replies and minimize repeats. If the number of players is odd, tsh will assign a bye to the lowest-ranked player who has had the fewest byes.

Round Robin Pairings

In Round Robin (RR) pairings, every player plays every other player once.

RR pairings are used when the number of players is no more than one more than the number of rounds scheduled. If the number of players is a little less than that number, than the remaining rounds are often paired KOTH. While RR pairings are fair and give each player the widest possible field of opponents, if the skill levels of the players vary greatly then it may be more fair to use a more flexible system that will allow the top contenders to play each other more than once. It is also difficult but not always impossible to schedule an RR so that contenders face each other in the final round.

Where the number of rounds is much larger than the number of players, RR pairings can be repeated, either with players playing the same opponent consecutively, or interleaved (where one RR is completed before the next one begins).

The general command for RR pairings in tsh is “rr n division”. For example, to ask for a double set of RR pairings to be added to division A, use the command “rr 2 a”. If you leave out the number “n”, a single set of RR pairings will be added. If you want to override the default ordering of round robin rounds, use “config random_rr_order = 1” or “config round_robin_order = [2,3,4,5,6,7,8,9,10]”. If you want interleaved RR pairings, use “config interleave_rr = 1”.

There is also a specialized command for doing partial round robin pairings for use at Cambridge ON. Use the “camp division” command to add fixed pairings for a seven-round tournament with any number of players.

If you want to assign round robin groups to noncontenders toward the end of your tournament, you can use the “LowerRoundrobins starting-rank rounds division” command. For example, if you want players to play three-round round robins in groups of four if they are ranked 41st or below in Division B, use the command “lrr 41 3 b”. It is a better idea however to use Fontes pairings (either Swiss or Chew) instead, because they will not cause any greater delay in the running of your event, and they do not involve using as stale results.

In fact, if you want to assign round robins throughout the entire field (subject to the caveat in the preceding paragraph explaining why it is a bad idea to do so), you can use the the “LowerRoundRobins starting-rank rounds division” command with starting-rank 1. For example, if you want everyone in Division C to play five-round round robins in groups of six, use the command “lrr 1 5 b”.

If you have an even number of teams of equal size, and you would like each player to play every player on every other team you can use the “teamroundrobin repeats division” command. For example, if you want the teams in division C to play each other twice, use the command “trr 2 c”. If you want to do something like “LowerRoundRobins” for teams, see the “TeamMultipleRoundRobin” command.

Bracket Pairings

Bracket pairings match players in a single-elimination format, with players out of contention playing KOTH. They can be tuned using the configuration options “bracket_order, “bracket_prelims and “bracket_repeats.

There is a manual command “BRACKetpair” that implements the pairing system, but you should never need to use it. It is available so that it can be invoked if you specify a bracket-paired event by adding the line “config pairing_system = 'bracket'” to your configuration file.

Double Elimination Pairings

Double elimination pairings were developed for Craig Beevers in Prague. They pair contenders randomly within win group; noncontenders are paired KOTH with minimal repeats. Players are removed from pairings after their second loss, and an alternate player is included whenever the total number of players would otherwise be odd.

The “DoubleElimination” command implements the pairing system.

Green Pairings

John Green’s tournaments in Florida use a system which pairs groups of six to eight players over six rounds, beginning with five fixed rounds.

There is a manual command “GREEN” that implements the pairing system, but you should never need to use it. It is available so that it can be invoked if you specify a Green-paired event by adding the line “config pairing_system = 'green'” to your configuration file.

Guelph Pairings

Andy Saunders’ tournaments in Guelph, Ontario use a system which pairs groups of six, eight or ten players over six rounds.

Six-player groups play a round robin followed by KOTH with repeats.

Eight-player groups play as follows. In rounds 1–3, 1458 (A) and 2367 (B) each play a round robin. In round 4: A1–B2 B1–A2 A3–B4 A4–B3. In round 5: A1–B1 A2–B2 A3–B3 A4–B4. In round 6: KOTH with infinite repeats and Gibsonization.

Ten-player groups play a depleted five-round round robin followed by KOTH with repeats.

There is a manual command “GUELPH” that implements the pairing system, but you should never need to use it. It is available so that it can be invoked if you specify a Guelph-paired event by adding the line “config pairing_system = 'guelph'” to your configuration file.

NAST Pairings

Steve Pellinen’s North American Scrabble Tour prescribes a specific hybrid pairing system for its satellite events. For most division sizes, this consists of four fixed rounds of pairings, one swiss-paired round with repeats allowed, and one KOTH round with unlimited repeats allowed.

There is a manual command “NAST” that generates the initial fixed schedule of four or five rounds, but you should never need to use it. It is available so that it can be invoked if you specify a NAST event by adding the line “config pairing_system = 'nast'” to your configuration file.

BASD Pairings

Ira Freehof’s Big Apple Showdown has its own pairing system. Players are divided into two round robin groups in a first phase, semifinalists play each other while everyone else plays small round robins in a second phase, and finalists play each other while everyone else plays factored pairings in a third and final phase.

This is implemented using the “config pairing_system = 'basd'” configuration option, which invokes the “BASDSemi” and “BASDFinal” pairings commands.

Swiss Pairings

In Swiss pairings, players are divided into “win groups” according to how many wins they have scored. The top half of each win group plays the bottom half, in order.

Several different systems of Swiss pairings are popular in Chess, where Swiss pairings originated. Swiss pairings work well for divisions where the number of players is large and the number of rounds is small.

Regular Swiss pairings cause delays in tournaments because the pairings for the next round cannot be computed until all the results are in for the previous round. Fontes (or Portland) Swiss pairings trade off some pairings accuracy for speed by computing pairings based on the second previous round’s results. As a compromise, some directors use regular Swiss pairings immediately after session breaks and Fontes Swiss pairings at other times.

The general command for Swiss pairings in tsh is “ns repeats based-on-round division”. For example, to ask for Swiss pairings with two repeats allowed, based on standings in round 17 for division C, use the command “ns 2 17 c”.

If you ask for Swiss pairings based on round 0, tsh will rank players by pretournament rankings, breaking ties randomly. This effectively pairs the top half of the field against the bottom, which may be something you want to do even if you aren’t pairing the rest of the tournament Swiss.

There is a special command for starting a Fontes Swiss tournament. Because you will need at least two rounds of scores before you can pair Fontes Swiss, the “InitFontes number-of-rounds division” command divides players into groups of four and schedules them to play in round robins. This takes three rounds (3 is the recommended value for number-of-rounds) and provides a fair start to the Swiss system, as well as giving you three hours to get used to doing data entry before you need to worry about pairings. If the number of players is not divisible by four, there may be a group of six players who play a partial round robin. The players in each group are chosen randomly, one from each quartile (or sextile).

Early in the tournament, you should use 0 repeats. At some point in a long tournament, you should start increasing the number of repeats or else the top players will begin playing much lower-ranked players because they have already all played each other. You can try simulating the outcome of the tournament to get a feel for when this is likely to happen, use your intuition based on past similar tournaments, or keep an eye on who the top-ranked player is playing each round and decide for example once they are paired with someone out of the top ten. Most Swiss tournaments end with one or two rounds of KOTH to ensure that contenders play each other often enough.

tsh chooses an opponent within the win group who (in decreasing order of importance): minimizes repeats, is not the previous round’s opponent, is due to play first if the current player is due to play second (and vice versa, but in either case only if “config track_firsts” is active), and is as close as possible to half a win group away in ranking. For the sake of computational efficiency, tsh looks for opponents first for those players who have the fewest candidate opponents (with ties broken by current ranking). If a win group is odd, the top player in the next group is promoted to join it. If a win group cannot be paired, two more players are promoted. If the entire division cannot be paired in one big group, an error message is displayed, and you should increase the number of allowed repeats. If the number of players is odd, tsh will assign a bye to the lowest-ranked player who has had the fewest byes.

By default, tsh pairs first the top win group, then the bottom win group, then the next win group at the top, then the next win group at the bottom, and so on. This saves time, because when the bottom players have all played each other, it saves tsh having to backtrack from every possible pairing of the higher ranked players. This optimization does however come at the cost of sometimes giving suboptimal pairings for mid-ranked players, especially in small divisions. To disable the optimization, use “config top_down_swiss = 1”.

By default, tsh pairs players within a win group by trying to match each player with an opponent who will balance firsts/seconds who is closest in rank to half the size of the win group away from the player. This behaviour can be changed using the “config swiss_order” configuration option, either to pair the top half in fixed order against the bottom half, or to minimize opponent rank distance.

Chew Pairings

Chew pairings draw on Swiss pairings and the two-victor “Basic Approach” pairing system developed for the 2003 CNSC and refined at the 2004 NSC, 2005 CNSC and 2005 NSC. Tournament simulations determine which players are still in contention; the minimum number of repeats required to pair those players is computed; the contenders are split into leaders and nonleaders so as to minimize the number of leaders while not increasing the required number of repeats. Beginning at the top, each leader is paired with the lowest-ranked other leader who can catch up to him/her; the nonleaders are paired Swiss.

Chew (or similar) pairings should be used in tournaments where after a number of preliminary rounds two or more top players are selected to compete in final rounds. They are also sufficiently flexible that they may be used in any sort of tournament, and are therefore used as tsh’s default pairing algorithm. As with Swiss pairings, they may be computed based on the immediately preceding round’s standings or those of the second preceding round, depending on event scheduling.

The general command for Chew pairings in tsh is “cp based-on-round division”. For example, to ask for Chew pairings based on round 5 in division D, use the command “cp 5 d”. As explained in the discussion on default pairings, if you do not specify any pairing system, manual or automatic, tsh will use Chew pairings. You must specify “config max_rounds” and should specify “config gibson_groups”, “config initial_schedule” and “config prize_bands” when using Chew pairings.

Here is a very sketchy version of how Chew pairing works. We calculate who is still in contention for top prize money and try to pair them with each other, pairing everyone else Swiss. The number of contenders is typically capped to 8 in the antepenultimate round, 4 in the penultimate round and 2 in the last round, making the last round KOTH at the top of the field, barring Gibsonization. The contenders are divided into two groups, called the leaders and the non-leaders, if this can be done without increasing the number of repeats. The leaders are paired by pairing each top unpaired player with the lowest ranked player who can catch him; the non-leaders are paired Swiss.

For example, suppose six people are in contention in the next-to-last round. This is too many for that round, so only the top four players are paired with each other. The top four players can be paired by allowing repeats but not threepeats. They can also be split into (1,2) and (3,4) without requiring threepeats, i.e. the 1-2, 3-4 pairing does not involve threepeats. So we pair 1-2 and 3-4. If (1,2), (3,4) did require threepeats, then (1,2,3,4) would be paired together. If 4 can still catch 1, then 1-4, 2-3; else if 3 can still catch 1 then 1-3, 2-4; else 1-2, 3-4.

Here is the Chew pairing algorithm in greater detail.

• Sort players according to standing in the specified round.
• Repeat while players remain unpaired.
  • Count Gibsons based on wins and spread. The largest possible number of Gibsons is determined by the number of ranks that are declared to be equivalent using “config gibson_groups” and is typically 0, 1 or 2. That number is reduced by one at a time while the lowest-ranked possible Gibson can be caught by the next-ranked player. To try to catch a Gibson, a player is assumed to be paired repeatedly with that player, and to win all his/her games with a spread of +250 in one round, +175/round in two rounds, or +150/round for more rounds (these values may be overridden by the “config gibson_spread” configuration option).
  • Pair any Gibsons. If the number of Gibsons is even and positive, pair them with each other KOTH but minimizing repeats and consecutive repeats; else if the number is odd, pair all but the lowest ranked one in this way, then pair the last one with either the highest-ranked player in the lowest prize band (if nonempty) or the lowest-ranked player overall, in each case choosing only from the candidate opponents who have played the Gibson least often. If the number of unpaired players is odd, give an odd Gibson the bye.
  • If the number of unpaired players is now odd, give a bye to the lowest ranked among the players with the fewest byes.
  • Determine the highest prize band that is still being contended.
  • Count how many contenders there are to reach that prize band. Add one if odd. Cap at 2, 4, 8, 12, 12, 12, ... players when there are 1, 2, 3... rounds left (this may be overridden in the configuration file using “config flight_cap”). Note that when there is one round left, this means that contenders are paired KOTH.
  • Determine the minimum number of repeats necessary to pair all the contenders with each other with no other constraints.
  • If all remaining players are contenders (or if there are six or fewer noncontenders, and no more than twice as many contenders, and they cannot play each other without repeats) and “config chew_no_swiss_all” is not in effect
    • pair them Swiss with that many repeats permitted.
  • Else (some players are out of contention)
    • Divide the contenders into leaders and nonleaders, minimizing the number of leaders (but keeping at least four where possible) as long as the subgroup of leaders and the subgroup of nonleaders can each be paired amongst themselves without exceeding the minimum repeats for the whole group of contenders.
    • Pair the leaders as a group by repeatedly matching the top player with the lowest ranked player who can catch him/her, while not exceeding the minimum repeats and where possible avoiding consecutive repeats.
    • Pair the nonleaders Swiss, not exceeding the minimum repeats, and where possible minimizing repeats, avoiding consecutive repeats and matching players due to start with those due to reply.

Ratings and tsh

How to maintain a rating system using tsh.

The “config rating_system” realm-dependent configuration option determines which rating system is in effect for your tournament. It can be overridden on a per-division basis by “config division_rating_system”.

One of the more popular features of tsh is its calculation of tournament ratings. When you set up your tournament’s “.t” files with information about your players, you enter their pretournament ratings, and if necessary their career game totals (depending on your rating system, you may be able to use the “USERATINGS” command to do this automatically). As your tournament progresses, you can display current ratings using the “RATings” and “ScoreBoard” commands. At the end of your tournament, you can submit ratings data to your rating officer using the “SUBMIT” command (if your rating system is supported), or by generating a ratings report using commands like “ABSPgrid” or “AUPAIR” and emailing the results.

The rest of this section describes in greater technical detail what is involved in connecting tsh to a rating system, and its intended audience includes ratings officers and directors who want to discuss tsh with their ratings officers. As always, if there is anything that tsh doesn’t yet do that you would like it to do, please contact John Chew at poslfit@gmail.com. Each one of tsh’s features is there because someone asked for it; if a feature is missing, it’s just because you haven’t asked for it yet.

Files

tsh stores pretournament rating information for each player in a tournament’s “.t” data files.

tsh stores information about rating systems in its “lib/ratings” folder. This folder contains one sub-folder per rating system. For historical reasons, NASPA ratings are stored as “nsa”. If you want tsh to support a new rating system, the first step is to ask John Chew to assign you a new, unique rating system name.

Rating system sub-folders contain contain files such as:

current.txt

the current ratings file, a text file that contains current ratings and possibly other information for each rated player

new.txt

the new ratings file, a text file that contains locally calculated new ratings and possibly other information for each rated player

MANIRATS.txt

the timestamp file, a text file that contains timestamp data used to tell whether or not the current ratings file is obsolete

Manual Rating Systems

Example users: Philippines, Toronto Speed

It’s easy to use tsh to run a small rating system for one or more people to use on one computer.

1. At the beginning of each rated event, use the “USERATINGS” command. This copies ratings from your current ratings file to your tournament data files.
2. At the end of your tournament, use the “EXPORTRATINGS” command. This creates a new ratings file.
3. Finally, save a copy of your old current ratings file in case you need to rerate a sequence of events (it happens more often than you would think), and replace it with the new ratings file.

Legacy Rating Systems

Example users: WESPA

If you have an existing legacy rating system that cannot easily be connected to the web, you should determine what ratings data format it uses (tsh currently supports its native format, Homan, Aupair and ABSP grid formats), and have your tournament directors e-mail the appropriate reports to your ratings officer. If you can persuade your ratings officer to post current ratings online, your directors can use the “USERATINGS” command.

Semiautomated Rating Systems (Type 1)

Example users: PSA

If you use more than one computer to run rated events but do not have a system set up to automatically receive online rating submissions, you can use an FTP client to maintain a shared rating database online.

First, ask John Chew to do the following:

• Set up an FTP account for you where you and your colleagues can store rating data.
• Set up a webpage that you can visit to register updates to your rating data. Its URL will include “update-ratings”.

Then, at each rated event:

1. Use the “UPDATERATINGS” command. This fetches the current ratings file from the FTP server.
2. Use the “USERATINGS” command. This copies ratings from your current ratings file to your tournament data files.
3. Run your event.
4. Use the “EXPORTRATINGS” command. This creates a new ratings file.
5. Use your FTP client to upload the new ratings file to your FTP account.
6. Visit the webpage that registers updates to your rating data.

Semiautomated Rating Systems (Type 2)

Example users: Scrabble Kenya

If you use more than one computer to run rated events but do not have a system set up to automatically receive online rating submissions, you can use a web client to maintain a shared rating database online.

First, ask John Chew to do the following:

• Set up a webpage that you can visit to post updates to your rating data. Its URL will include “post-ratings”.

Then, at each rated event:

1. Use the “UPDATERATINGS” command. This fetches the current ratings file from the FTP server.
2. Use the “USERATINGS” command. This copies ratings from your current ratings file to your tournament data files.
3. Run your event.
4. Use the “EXPORTRATINGS” command. This creates a new ratings file.
5. Use your web client to upload the new ratings file. Note that this step could be done by a different individual (a ratings officer) from the previous step, in order to retain more control over the addition of rated events to the rating system.

Automated Rating Systems

Example users: ABSP, NASPA

If you have a large rating system or like automation, you should set up (or ask John Chew to set up) a web page to which your tournament directors can upload ratings data using the “SUBMIT” command. Once it’s uploaded, your web site may immediately calculate new ratings and make them available for download to the “USERATINGS” command, or it may hold them for manual verification, as NASPA currently does.

Scoreboard Operations using tsh

How to enhance your tsh experience.

This section discusses specific issues related to the operation of the scoreboard using tsh and may safely be ignored if your tournament does not use the scoreboard.

What is the Scoreboard?

The scoreboard is a web page, called the Enhanced Scoreboard in the event HTML index, which periodically checks for updated score information and presents it in a browser page in a variety of formats.

How does the Scoreboard Work?

Here's an overview.

1. You initially create a scoreboard document for each division using the “ESB A”, “ESB B”, etc. commands.
2. These documents, along with the rest of your web files, must be accessible on an actual webserver and not just being viewed from your desktop (or else most browsers will prevent the code in the scoreboard from running for security reasons).
3. You arrange for the data file that the scoreboard checks to be automatically updated using triggered/hooked invocation of the “JSON” command, and remember to run it manually in other unusual situations.
4. If you are hosting your web files on another server, you make sure that they are copied there on a regular basis, e.g., using the “util/mirror-ftp” command.

Step-by-Step

1. Create Scoreboard Documents

First, add a line like the following to your configuration file:

begin esb a; esb b; esb c; json

This tells tsh that when it starts running, it should create the scoreboard document for divisions A, B and C (change that part if you have different divisions), then update the scoreboard data file. If the scoreboard documents or data file already exist, they will just be updated.

Check the results of the first step by running tsh and using the “Browse” command to show you the event index. You should see your enhanced scoreboards listed at the top. Don’t worry about clicking to see their content yet.

2. Set up a Webserver

Next, you need to get the files onto a webserver. If possible, you should always try to run a webserver locally on your data entry machine, even if you are also mirroring files to a public webserver, because it will result in faster updates to your scoreboard without waiting for your data to make a round-trip off-site.

I may eventually include operating-system specific instructions for how to enable the webserver that comes with your computer. In the meantime, if you use Windows, try Googling for "Internet Information Server", "install", and the name of your version of Windows; if you use macOS, Google for "apache" or "web server", "enable", and the name of your version of Windows; if you use Linux, ""apache", "configure", and the name of your version of Linux. In each case, you'll eventually end up with a local directory where your webserver expects to find your files. Use the “config html_directory” configuration option to specify this to tsh.

If you cannot set up a local webserver (e.g., because it violates a security policy, or it is too difficult), you should find someone who can provide you with FTP access to a public webserver. If you are a NASPA-certified tournament director, you are entitled to a free FTP-based webserver account on the NASPA server; contact John Chew at <poslfit@gmail.com> to ask for one to be set up.

3. Set up Data Updates

Add lines like the following to your configuration file:

config hook_addscore_flush = 'json'
config hook_autopair = 'json'
config hook_division_update ='json'

These tell tsh to run the “JSON” command respectively whenever the “Addscore” command saves its data, whenever new pairings are created automatically or by default, and whenever the division data files are updated.

If you notice at any point later on that the scoreboard's data does not reflect a recent change (especially one that you made by hand), you can run the “JSON” command to update the data. Note though that the scoreboard checks for data only once every 10 seconds (see the countdown at the top right), and that if you are copying data to a remote webserver, it may take up to a few minutes for it to reach its destination.

4. Copy Files Off-site

If you are using an off-site webserver, you should use the “util/mirror-ftp” command to automatically copy (mirror) your web files to it. This command runs separately from tsh, in a different window, and how you launch it depends on your operating system. Like tsh, if you run it without specifying an event folder, it will work with the event that has the most recently changed configuration file. Unlike tsh, you can specify multiple events on its command line, and it will mirror all of them.

Before you start the mirror process, you need to add lines like the following to your configuration file:

config ftp_host ='www.scrabbleplayers.org'
config ftp_path ='tsh'

These specify the name of the host that will receive the data files, and where the files should be placed on that host. The files will actually end up in a subdirectory of the path that you specify, where the subdirectory has the same name as your local event folder. For this reason, you should avoid using characters other than letters, numbers, hyphens and underscores in your event folder name.

Then, when you are sure that you have a working Internet connection, try launching the command. If you can open a command window and navigate (using your operating system’s “cd” command to change directories), you can then enter one of:

perl util\mirror-ftp REPLACE-THIS-WITH-EVENT-FOLDER-NAME
util/mirror-ftp REPLACE-THIS-WITH-EVENT-FOLDER-NAME

Use the first one for Windows, the second for everyone else. You may omit the part about the folder name if you are using your most recent event folder. You may also find a clickable script icon in the utility folder that saves you having to do all of the above, depending on your operating system.

If all goes well, you should at this point be prompted for your username and password. These are the ones that you use to connect to your FTP server. The password will not be displayed on the screen as you type; it will be accepted when you press enter. Then, if your username and password match, you will see your files start transferring. Leave the window open for as long as you need them to keep mirroring. Restart the command/window if your network connection changes.

Scoreboard Banners

You may wish to display a banner above the scoreboard, showing things like a legend or sponsor logos. To do so, make the banner content publicly available on a webserver, then specify its location and height with lines that look like:

config sb_banner_url = "http://event.poslfit.com/2017/kingscup/banner.html"
config sb_banner_height = 128

Scoreboard Geometry

By default, one scoreboard file is created per division, displaying a grid of five columns and four rows. You can override these three values using the “config esb_geometry” configuration option. For example, to set up Division A with one scoreboard showing 6 columns and 5 rows starting at the top of the field, and another scoreboard showing 5 columns and 4 rows starting 30 places down, use:

config esb_geometry{'A'} = [[5,6,0],[5,4,30]]

AUPAIR

Scoreboard Operations using tsh

How to enhance your tsh experience.

This section discusses specific issues related to inter-operation with AUPAIR using tsh and may safely be ignored if you do not need to work with AUPAIR-based rating authorities.

What is AUPAIR?

AUPAIR.EXE is a program used by Bob Jackman and his WESPA Rating System, and to run many national rating systems in Southeast Asia. The most common reason for reading this document is a need to export tournament results from tsh to AUPAIR-based rating systems.

How can I work with AUPAIR in tsh?

Here's an overview.

1. You initially create a scoreboard document for each division using the “ESB A”, “ESB B”, etc. commands.
2. These documents, along with the rest of your web files, must be accessible on an actual webserver and not just being viewed from your desktop (or else most browsers will prevent the code in the scoreboard from running for security reasons).
3. You arrange for the data file that the scoreboard checks to be automatically updated using triggered/hooked invocation of the “JSON” command, and remember to run it manually in other unusual situations.
4. If you are hosting your web files on another server, you make sure that they are copied there on a regular basis, e.g., using the “util/mirror-ftp” command.

Step-by-Step

1. Create Scoreboard Documents

First, add a line like the following to your configuration file:

begin esb a; esb b; esb c; json

This tells tsh that when it starts running, it should create the scoreboard document for divisions A, B and C (change that part if you have different divisions), then update the scoreboard data file. If the scoreboard documents or data file already exist, they will just be updated.

Check the results of the first step by running tsh and using the “Browse” command to show you the event index. You should see your enhanced scoreboards listed at the top. Don’t worry about clicking to see their content yet.

Kenyan Users

tsh for Kenyan Users

Instructions specific to directors` who use tsh in Kenya.

This section discusses specific issues related to operating tsh at Kenyan tournaments, and may safely be ignored if you are not working in Kenya.

How to tell tsh that you are a Kenyan user

To enable Kenyan features in tsh, add the following line to your configuration file:

begin realm = 'ken'

This tells tsh to operate under the Kenyan realm. A realm is a set of default configuration values for a group of users. In this case, tsh will know to do things such as:

• use the Kenyan photo database
• use the Kenyan currency_symbol (K)

How to add photos to the Kenyan database

Adding photos to the Kenyan photo database requires access to the database FTP server. If you are not the designated photo administrator (as of 2018, Powell Cheruiyot), please contact them for assistance. If you are the photo administrator, please keep reading.

Kenyan users of tsh will have a local copy of the photo database in the “lib/pix/ken” subdirectory of your tsh directory (folder). This gets updated from the primary copy on a webserver whenever they run the “UPDATEPIX” command.

The photo database consists of directories containing photos of the players, together with an index file called “photos.txt” that tells tsh which photo corresponds to which player name. You may freely choose how to organise the photos into subdirectories; it is of course best to do so systematically.

Whenever you add, rename or delete photos, you must update the index file using WordPad (Windows), TextEdit (MacOS) or a similar tool. The index file has one line per player, and each line has three tab-separated fields. The first field is the player’s given name (forename), the second field is their surname (family name), and the third field is the case-sensitive photo filename (possibly including directory names if it is in a subdirectory). So, for example, if a player with a photo stored in “lib/pix/ken/c/chew_john.jpg” is listed in “a.t” this way:

Chew, John 1800 

then they should be listed in photos.txt this way:

John<tab>Chew<tab>c/chew_john.jpg

To update the primary copy on the webserver:

1. Make the changes to your local copy of the photo database, including the index file.
2. Use an FTP client to copy the files from your local copy to the webserver. If you need the username and password, contact John Chew at poslfit@gmail.com.
3. Run the update script on the server to register the changes.
4. Run the “UPDATEPIX” command to verify that the changes are available for download.

Team Play using tsh

Managing team tournaments with tsh.

This section discusses specific issues related to running team tournaments using tsh and may safely be ignored if your tournament does not have teams.

What is a Team Tournament?

A team tournament is one in which each player may be affiliated with a team for the purposes of calculating pairings and standings. Don’t confuse teams with what tsh calls classes or prize groups, which are used solely for calculating prize eligibility.

There are two types of team tournaments, which tsh handles in the same way, except that some commands will not work very well with one type or the other. In some team tournaments, such as the World Championships, you will want to avoid having players from the same team play each other under some circumstances, and you will want to report on team standings, but your event is otherwise essentially an individual one. In others, such as interclub matches, the entire pairing schedule is based on who is on which team, and individual results are secondary to team results.

Setting up a Team Tournament

To begin, you will need to manually designate who is on which team. You do so by adding an extension field to your “.t” files. Here is a very short example.

Man, Anpan   2000 ; ; team Good
Ojisan, Jam  1500 ; ; team Good
Man, Baikin  2000 ; ; team Evil
Chan, Dokin  1800 ; ; team Evil

In your configuration file, you may want to use the “config initial_exagony” option to specify that teammates do not play each other in the first rounds (as at the Worlds), or the “config exagony” option to specify that they should never do so. You should probably use the “config show_teams” option to specify that team names should be displayed along with player names where appropriate. You may want to have a prize configuration line awarding prizes for best team records.

Team Tournament Pairings

Most pairing commands that pair players in a single command will respect the exagony configuration options. These include the more commonly used commands: “ChewPair”, “KOTH”, “NewSwiss” “PairQuartiles”.

Unless otherwise indicated, commands which pair multiple rounds do not currently obey the exagony configuration options. These include the more commonly used commands: “InitFontes” and “RoundRobin”.

If you want something like initial Fontes pairings, you can use automatic pairings to specify three rounds of quartile pairings, pairing the top quartile successively with the bottom, third and second quartiles. This will differ from initial Fontes pairings in that the pairings in those three rounds are independent and will typically not consist of round-robin groups of four; they will resemble initial Fontes pairings in that each player will face opposition of collectively similar strength.

The usual round robin pairings are of course incompatible with team tournaments. Instead, you can use the “TeamRoundRobin” command to generate team round robin pairings: those in which each player plays everyone on every other team.

Team Tournament Reports

If you use the “config show_teams” configuration option, then regular report-generating commands like “RATings” will display team names where player numbers are shown after player names. In the example above, you might see “Man, Anpan (#1/Good)”. If you use this example, it's a good idea to keep team names short: if your teams are countries, you could use ISO 3166-1 alpha-3 codes.

In this case, the “ShowPairings” command will also generate a separate set of team pairings, which can be distributed to a team coach, so that they can tell all of their team members where to go and whom to play.

In addition to the usual tsh commands, you may wish to use the “TeamStandings” command to report on team standings on a division by division basis, or the “TotalTeamStandings” command to do so for the tournament as a whole.

Caveat

A large majority of events run using tsh are not team tournaments. Please be sure to use the “DRYRUN” command before your event to make sure that tsh does what you want it to do, and contact John Chew well in advance of your event if you need new features added.

What’s New in tsh

A chronological list of changes to tsh.

Changes are made to tsh for just about every tournament at which it is used. This means two things: firstly, you should be sure to update to the most recent version before your tournament; and secondly, if there’s a feature that you’d like added please be sure to mention it, preferably with about a month’s lead time.

Version	Event	Changes
3.340	Development	Added new “config pname_from_sbname = 1” configuration option for having pname default to sbname (Vince Castellano).

3.280	2009 Toronto SCRABBLE Tournament	“PRiZes” command handles ties better (Ross Brown). The “NAST” command works with all well-defined seven- and eight-round events (Steve Pellinen). “config oppless_spread = 1” indicates that spread calculations should ignore opponent scores (and therefore be just the sum of a player’s own scores (Johann-Georg Dengel). “separator” prize type no longer uses up a prize number (Ross Brown). “showWallChart” displays paired unscored rounds, supports terminology internationalization (Johann-Georg Dengel). Added “showRankedWallChart” command (Johann-Georg Dengel). “config no_boards = 1” suppresses only boards, not tables (to avoid tables, don’t use “config tables”. The “absp” realm now uses “config entry = 'scores'” as its default (Stewart Holden). Non-ASCII characters in foreign terminology are reduced to ASCII for console output. “STandings” command output looks more like “RATings” command output (Johann-Georg Dengel). Changed “UpdatePLAYers” command to better cope with errors in cross-tables.com data (Ryan Fischer) Updated “ABSPgrid” command, which now combines divisions (all, if none are specified) into one grid. (John Grayson, Stewart Holden) “PRiZes” command can now read group members from a file. “PRiZes” command group members no longer have to all belong to the same division. Updated “ROTO” command, which now accepts an optional round number “util/mirror-ftp” no longer gives up if it has no Internet connection. “ShowPairings” command correctly places players at tables by rank even when School SCRABBLE capped standings are in effect (Joey Krafchick). The “currency_symbol” configuration option can now override the default dollar sign in scoreboards. Tweaked “ChewPair” command to improve pairings specifically for 12-round events with 14-18 players. The leader/nonleader split now always includes at least 4 leaders where possible, and the faint hope clause now applies in the penultimate round as well as the last. The “PairMany” command now accepts player names (Art Moore). The “EditScores” command now lets you manually assign board numbers. The “PRiZes” command allows the “winner” parameter to override a computed winner, which can be useful in events with a separate finals round. The “RoundHandiCap” command reports on King's Cup-style handicaps. The “ScoreBoard” command works better when displaying a group that isn't at the top of the field. The “ScoreBoard” command has specific knowledge of Thai names, and Malaysian/Singaporean names of Chinese origin, and renders them appropriately. The “THAICASH” command reports on King's Cup-style winner's bonuses. The “config force_koth” configuration parameter will accept greater values than 1, and set up that many final rounds of KOTH. The “config player_photo_aspect_ratio” configuration parameter specifies aspect ratio of player photos (Stewart Holden). The “SUBMIT” command now sends data to NASPA, not the NSA. The “config director_id”, “config director_password” and “config tournament_id” configuration parameters have been added and are what are now required for automatic ratings submission to NASPA. The “UPDATERATINGS” command works with NASPA ratings (Andy Saunders). The “USERATINGS” command warns about player NASPA membership status (Andy Saunders). The “SUBMIT” command prompts for a password if it does not find one in the configuration file (not yet tested under Windows) (Andy Saunders). The “PairMany” command records firsts and seconds if “config track_firsts = 1” is in effect (Mauro Pratesi). The “AUPAIR” command omits byes/forfeits rather than faking them as ties if “config no_aupair_bye_ties = 1” is in effect (Henry Yeo). The “SUBMIT” command prompts for a password if it does not find one in the configuration file, even under Windows (Bryan Pepper). The “SUBMIT” command generates a complete all.tsh file even if the network connection fails (Carole Denton). The new “GREEN” command generates 6-round pairings for 6-8 players as specified by John C. Green (John C. Green). The “Addscore” command does not abort as often on incorrect input (Andy Saunders). The “USERATINGS” command correctly handles the case where a player has a rating in the data file but not in the rating list. The “EditScores” command now lets you assign spread penalties (Andy Saunders). The “config final_draw = 1” option specifies that even when firsts and seconds are assigned, players with even records in the last round will be instructed to draw randomly to see who starts (Ian Weinstein). “config rating_system = 'thai'” gives a rating system equivalent to NSA 2008 that does not count tie games (Ravee Joradol). The “Addscore” command keeps track of input speed. The “EXPORTRATINGS” command exports a new rating list, for those using tsh to maintain a rating system (Ravee Joradol). The “USERATINGS” command warns about suspended player NASPA membership status (JC Green). Trying to use “config force_koth” with automatic pairings gives an error message, may abort tsh in future (Bryan Pepper). The “SUBMIT” command works with nonstandard filenames (Dave Johnson). “RATings” command now does not show the rating difference column for ABSP users (Stewart Holden). “ScoreBoard” command does not include future rounds in counting repeats (John O'Laughlin). Cosmetic improvements to the “ScoreBoard” command (Ross Brown). Cosmetic improvements to cross-tables, scorecards and wall charts.
3.270	Toronto School SCRABBLE Championship	“util/mirror-ftp” is easy to configure (Jared Robinson). The “EditScores” command now lets you edit byes (Dallas Johnson). The “NAST” command works with five-round events (Sherrie Saint John). “config rating_system = 'elo'” indicates that Elo ratings should be computed without NSA bugs. Many more NSA rating system bugs are more correctly duplicated. “config rating_list = 'deu'” specifies the use of the German ratings list. “UPSETs” command displays decimal ratings differences correctly (Stewart Holden). Improved “ChewPair” command, applies pairings cap to players within one win of last prize in the last round, effectively extending the KOTH group in the default situation. “PRiZes” command can now compute prizes based on results of a selected range of rounds. “ScoreBoard” command displays team flags if available, design improvements. new rating systems and rating lists, details to follow. “config realm = 'deu'” added, uses German ratings list, rating system and some terminology in common reports (Heinz-Jürgen Michel). “config rating_system = 'wespa'” specifies the use of the WESPA rating system. “config rating_system = 'aus'” specifies the use of the Australian rating system. “config rating_system = 'nsa2008'” specifies the use of the new NSA rating system. “config gibson = 'strict'” pairs Gibsons with the highest player out of contention, no matter how many times they have played the Gibson (Jim Hughes). “util/mirror-ftp” automatically copies tsh reports to an FTP server whenever they change. “Addscore” command correctly reports updated win total on entering a scoreless bye (Stewart Holden). Added new command “GUELPH” to support new pairing system (“config pairing_system = 'guelph'”) used in Guelph, Ontario, Canada (Andy Saunders). Corrected the calculation of local club ratings that change across multiplier boundaries. Corrected the calculation of ABSP ratings in nonfinal rounds. HTTP clients now try to reconnect 25 times rather than giving up right away. Computed new ratings are saved in .t files (as newr). Ratings for the default 'nsa' realm are now computed using the new logistic rating curve. Fixed bugs in “UpdatePLAYers” command (Andy Saunders) Fixed bug in bye-assignment algorithm that could cause a crash if data files were manually edited outside of tsh (Rajiv Antao). “ScoreBoard” command correctly displays half-win banners (Ross Brown). “ScoreBoard” command respects “config no_boards = 1” (Ross Brown). “config hook_division_update = 'command1;command2;...'” fires on any update of any division data file (Ross Brown). Corrected “SUBMIT” command to handle configuration files that do not end in a newline character (Carla Cree). “util/mirror-ftp” can be run from its subdirectory (Stewart Holden). “HighCombined” command shows classes for both players (Stewart Holden). “UpdatePLAYers” complains and does not try to update data files if cross-tables.com returns an error message (Ryan Fischer). “util/mirror-ftp.bat” added for Windows users (Stewart Holden). Negative prize ranks count from the bottom of the field (Ryan Fischer). “util/mirror-ftp” syntax changed to permit specifying both username/password and event list on command line (Andy Saunders). Corrected two serious bugs in the “KOTH” command that could cause incorrect pairings in divisions with odd numbers of players, and failure to detect Gibsonization (Stewart Holden). “ChewPair” command now works better with “config exagony = 1” (Ryan Fischer). Added “config html_index_bottom” and “config html_bottom”, to offer customisation of web report footers (Ryan Fischer). Added “config custom_stylesheet” to specify an event-specific CSS stylesheet to override defaults in the standard tsh stylesheet (Ryan Fischer). Corrected a bug in the “ChewPair” command that caused rare crashes during Gibsonisation (Ryan Fischer). “RANDomscores” generates reasonable scores for ABSP divisions even when the ratings are unreasonable (Ryan Fischer). Cleaned up and documented the “overseed” prize type (Ryan Fischer). Added the “separator” prize type (Ryan Fischer). “PRiZes” outputs a blank prize chart if run at the beginning of the tournament (Ryan Fischer). Added “BRACKetpair” command and “config bracket_order”, “config pairing_system = 'bracket'” and “config bracket_repeats = 3” configuration options to support single-elimination pairings (Jason Idalski). Corrected a bug in format of POSTed data in HTTP client code. Added “password” extension field in preparation for self-service scoring. Added the “TWEET” command and the config twitter_username, config twitter_password, config twitter_prefix and config hook_division_complete{'A'} configuration options. Added the “TotalTeamStandings” command to list total standings for a team with members in multiple divisions. Added the “totalteam” prize type. “ScoreBoard” command displays players out of contention in blue (Ross Brown, implemented by Ross Brown). Documented the “bracket_cap” configuration option. Documented the “bracket_noncon_pairings” configuration option.
3.260	2008 Big Apple ST	Added “config division_rating_system{'A'} = 'none'” which overrides “config rating_system” on a per-division basis (Andy Saunders). Removed “config max_name_length”, which is no longer necessary as all tables are dynamically formatted. Removed “config name_format”, which is no longer necessary as all tables are dynamically formatted. “RESETEVERYTHING” also deletes ‘prizes.doc’ (Brad Mills). “RoundRATings” command now uses vulgar fractions, correctly handles empty divisions, correctly handles “config no_boards = 1”. “ShowPairings” command now correctly handles “config no_boards = 1”. Commands triggered by hooks do not change which report “BrowseLast” displays. “config avoid_sr_runs = 1” is now the default setting in the ABSP realm (Paul Thomson). Added experimental new command “UpdatePLAYers”, which uses the new configuration variable “config cross_tables_id” to choose and download a player roster from cross-tables.com.
3.250	2008 MWMST	The “EditScores” command now lets you set a player’s life games total (necessary for accurate computation of NSA ratings) using the “GAMES” keyword (Leonora Labog). Added “BASDSemi” and “BASDFinal” commands, and “config pairing_system = 'basd'” configuration option (Ira Freehof). Added “config round_robin_order”, which lets you explicitly specify a nonstandard order for the top player’s opponents in a round robin (Ira Freehof). Corrected some serious issues affecting Gibsonization mainly for UK directors (Richard Blakeway). Corrected some less serious issues affecting Gibsonization: tsh could crash if all players in a division were involved in Gibsonization, especially in a small division (Richard Blakeway). Adjusted the threshold at which tsh will refuse to merge contenders and (six or fewer) contenders (who cannot be paired without repeats) from C≤NC to C≤2NC (Ryan Fischer). “EditScores” can be invoked on any paired round, not just a scored rond. “PRiZes” command now has new “class” extra item for designating class prize eligibility. Redesigned the “ScoreBoard” command and added the config hook_autopair configuration option. NSA ratings computed while results are being entered are no longer computed incorrectly for players whose results have not yet been entered (Sal Desiato). “ShowPairings” used to not show pairings immediately after computing them if everyone was a gibson, a victim or a bye. “TeamRoundRobin” command works if one team has one less player than the other (Mike Frentz).
Version	Event	Changes
3.240	US NSC 2008	“showScoreCard” command indicates repeat pairings (Stewart Holden) Added “TeamRoundRobin” command. Corrected “SUBMIT” command to handle .t files with missing final newlines (Brett Constantine). Improved “ChewPair” command, runs faster for large divisions by doing even fewer unnecessary best-possible-finish computations. “CheckRoundScores” command no longer displays inactive players. Added “config html_index_top”, which provides an alternate HTML heading to be used for the Event Coverage Index. Added “config bye_firsts = 'alternate'”, to support new NSA scheme for assigning firsts and seconds to players who have had byes, is now default for realm 'nsa'. “Addscore” command no longer cares if you put extra zeroes in front of player numbers (Jeremy Brooke). “PRiZes” command now has a relatively easy configuration syntax and supports several new prizes for the NSC. “HighRoundLosses” command replaces earlier “high-loss-round” external command (Jeremy Brooke). “HighRoundWins” command replaces earlier “high-win-round” external command (Jeremy Brooke). Regression testing works better under Windows now. Added “config mirror_directories = [qw(path1 path2)]”, to automatically copy ‘.t’ files to other directories. The “EditScores” and “EditScores” commands no longer display division names with player numbers if there is only one division in the event (Jeremy Brooke). An error is reported at run time if a division has an odd number of active (formerly active or inactive) players (Jeremy Brooke). “DELETEscore” command can now be used to delete byes, giving an opponent number of 0 (Jeremy Brooke). “UnPairRound” command works correctly with players who have a scored bye in the round being unpaired (Jeremy Brooke). “UPDATE” command is now internal, should no longer fail to report its progress for Windows Users (Jeremy Brooke). “ShowPairings” alpha pairings indicate firsts and seconds more clearly (Mary Rhoades). “UPDATEPIX” command is now internal and has lost its hyphen. “RoundRATings” command now accepts a range of rounds to compute (Jeremy Brooke). “SHOW12” command is now internal and slightly enhanced (Jeremy Brooke). Pairings commands now correctly detect triple Gibsonization (Bryan Pepper). “STATisticS” command reports total number of points scored and games played (Patty Hocker). Added “UPDATERATINGS” command (Jeremy Brooke). Added “USERATINGS” command (Jeremy Brooke). “config initial_snaked = 1” behaviour corrected in case where you are just one player short of the right number (Johann-Georg Dengel).
3.230	2008 CNSC, BAT, etc.	“Addscore” command largely rewritten, now accepts ‘.’ as equivalent to ‘ ’ (space) to facilitate numeric keypad data entry, reports computed spread when entering scores, also supports new “config entry = 'both'” to require the entry of entry of both scores and spread. Fixed a bug that could cause tsh to crash if it tried to pair an empty flight, as could happen if all players were part of a Gibsonisation process (Ryan Fischer). “config gibson_class = 'A'” restricts Gibson opponents to the named class (Stewart Holden). The U.K. now has a separate player photo database (Stewart Holden). Added the “ScoreBoard” command and the config hook_addscore_flush configuration option that enables its automatic invocation. Corrected recently introduced serious errors in “ChewPair” affecting default flight cap pairing in final round, and late rounds with odd numbers of contenders. “HighWin” and similar commands now display player classes if available. “config initial_snaked = 1” causes “InitFontes” to snake players boustrophedonically into groups, rather than assigning them randomly by quartile (Yeo Kien Hung). “config standings_spread_cap = [100, 150, 250, 250, 250, 250]” caps allowed spread per round for standings purposes, for the U.S. NSSC. “config alpha_pair_single_column = 1” displays alpha pairings in one column (Ben Greenwood). “ChewPair” runs a little faster now by not checking Gibsonization below last prize rank. Division names appearing in configuration variables can be in lower case. (Mary Rhoades) The “ScoreBoard” command no longer gives spurious error messages if invoked with no arguments (Ryan Fischer). Multiple commands may now be entered on a line, separated by semicolons. Added experimental “LowerRoundRobins” command to implement a very poorly thought out pairing system, formerly popular at the U.S. NSC (Kien Hung Yeo, Chris Lennon). Fixed a bug that caused “ChewPair” to crash if scores for the previous round were entered before Fontes pairings were generated (Mary Rhoades). Added “ROSTERS” command (Mary Rhoades). Altered “ChewPair” to raise the threshold from four to six at which a number of noncontenders forced to repeat pairings by being prevented from playing with contenders are allowed to play with them after all (Mary Rhoades). “ShowPairings” now mentions repeat pairings (Mary Rhoades). Fixed a bug in “ChewPair” that would cause it to hang if the top flight had to include someone who couldn't catch up to the player above them (Mary Rhoades). Corrected “AUPAIR” CR LF problem (Yeo Kien Hung). “config rating_system = 'none'” indicates that no ratings should be calculated (Karey Heard). Corrected “STATistics” command to run correctly when division names are numerical (Karey Heard).
3.220	2008 Dallas Open	“STATisticS” command now invokes all other statistics commands (Stewart Holden). “config assign_firsts = 1”, “config html_in_event_directory = 1” “config track_firsts = 1” are now default in ABSP realm (Stewart Holden). Corrected “AUPAIR” to handle ties correctly (Bob Jackman). Some browsers were not correctly rendering empty cells in tabular reports. (Ricky Purnomo). “ChewPair” was incorrectly estimating contention in many cases, resulting in unnecessary late round repeats (Stewart Holden). “ChewPair” now checks to see if four non-contenders can't be paired without repeats, not just two (Glenn Dunlop). Added “config avoid_sr_runs = 1”, which tries to minimise runs of starts and replies before randomly assigning them to players whose records are equal. Experimental Linux browser support added (Prithwiraj Mukherjee). “RESETEVERYTHING” was incorrectly deleting ‘tsh.css’ (Ryan Fischer, issue 86). “config no_initial_rr = 1” tells Chew pairings not to start with initial round robins, even if there are enough rounds to do so (Stewart Holden). Rewrote round robin code to use Berger schedule. “InitFontes” now accepts any odd number as its first parameter, not just three (Stewart Holden). “FactorPair” supports Gibsonization (Carla Cree). Ratings no longer have to be whole numbers (Stewart Holden). “config random_rr_order = 1” puts round robin pairings in random order (Ronan Webb). “STATisticS” command suppresses meaningless figures depending on “config assign_firsts” and “config track_firsts”(Stewart Holden). The HTML index will include possibly blank rows for each round if “config max_rounds” is set (Stewart Holden). “ChewPair” command works much faster now in large divisions by truncating the search for contenders at the flight cap. “PRiZes” command calculates upsets automatically. “STATisticS” command correctly calculates stronger player winning percentage even when players are numbered alphabetically (Stewart Holden). “STATisticS” command hides output from invoked commands. Scorecards displayed on-screen do not include empty rows for rounds not yet played.
3.210	WSC 2007	“config initial_random = 1” added, specifies one initial round of random pairings when automatic pairings are in effect. “ShowPairings” command now displays or suppresses start/reply data depending on configuration settings, no longer relies on user to edit ‘tsh.css’ (Sherrie Saint John). “ShowPairings” command no longer tries to make two columns if player photos are being shown. “CheckRoundScores” command displays player names. “config check_by_winner = 1” added, specifies checking of scores by winner even when starts and replies are being tracked. “TeamStandings” command displays more statistics. Added “RESETEVERYTHING” command to reset everything (Stewart Holden). Added “NAST” command to do NAST pairings. Added “config pairing_system = 'nast'” for North American Scrabble Tour events. Added “config show_last_player_name = 1” to show last player name and not just ID in ratings reports (Jim Hughes). Added “config no_boards = 1” to completely suppress boards (Ricky Purnomo). “SUBMIT” command opens browser window to payment screen (Jim Hughes).
3.200	2007 Big Apple ST	“config realm = 'sgp'” added, suppresses errors about lack of comma in player names in “AUPAIR”. Added “config surname_last = 1”, is default in ABSP realm (Stewart Holden, issue 8). Added “config sort_by_first_name = 1” which sorts alpha pairings by first name, when “config surname_last = 1” is in effect. An ActivePerl bug that closed that sometimes standard output filehandle when forking a browser process has been worked around by saving and restoring the handle. (Stewart Holden, issue 68). Added “DRYrun” command that simulates one run of a tournament for a division. Added “config max_div_rounds{'A'} = 5” which overrides “config max_rounds” on a per-division basis (Ricky Purnomo). “Addscore”, now accepts player names without commas. (Ricky Purnomo). Added “config no_ranked_pairings = 1” to display only alphabetical pairings tables (Stewart Holden, issue 4). Fixed a problem with “HighLoss” and similar commands (Stewart Holden, issue 79).
3.190	September 2007 Toronto 2007 UK NSC Semi-Finals	“Addscore”, was complaining too much about scores when “config entry = 'spread'”. (Reported by Stewart Holden). Added “SPITroast” command for UK-style rotisserie pools (Evan Simpson, issue 6). Added “STATisticS” command for generating summary statistics for a tournament. “MISSing” now accepts an optional second argument, a division name (Stewart Holden, issue 5). “RANDomscores” ABSP-unrated player score distribution bug fixed (Stewart Holden, issue 43). “KOTH” and other standard pairings commands honour “config gibson=1”(Stewart Holden, issue 33). “config prize_bands” defaults to one quarter of division size, not one. Added “luckySTIFF” command as opposite for TUFFluck (Stewart Holden). Added “SPITroast” command for UK-style rotisserie pools (Evan Simpson, issue 6). ‘tsh.css’ is now copied to the event directory when “config html_in_event_directory = 1” is in effect. (Stewart Holden, issue 62). Corrected “AUPAIR” to handle byes correctly (Barry Harridge, issue 63). Massive code changes made to support simultaneous (multithreaded) operation of the web server and command-line interface. Regression testing implemented, see ‘util/regression.pl’. “config alpha_pair_page_break = 10 ” is now the default value in the NSA realm (and 10000 in the ABSP realm), and is used to determine whether or not to switch to two-column printing when no photos are used. (Stewart Holden, issue 65) “TUFFluck” is now a built-in command, not an external one, the order of its arguments is reversed, and it generates HTML files (Stewart Holden).
3.180	2007 Players Championship	HTML reports are now generated only in the directory (folder) designated by “config html_directory”, and no longer in the event directory. This is because reports which included player photos were not able to refer correctly to the location of those photos. If you find this confusing, use “config html_in_event_directory = 1”. (Reported by Jennifer Miller). Added “Browse” command. “config bye_spread” defaults to 50, but can be set to 75 for ABSP use (for Stewart Holden). “config realm = 'absp'” sets various configuration variables to ABSP defaults, also chooses alternate default ‘tsh.css’ file which shows starts/replies but suppresses boards. Added “DOCumentation” command. Rewrote “HighLoss” command, now generates HTML, does not have hyphen in its name. Rewrote “HighWin” command, now generates HTML, does not have hyphen in its name. Rewrote “LowLoss” command, now generates HTML, does not have hyphen in its name. Rewrote “LowWin” command, now generates HTML, does not have hyphen in its name. Added “AVErages” command for Stewart Holden. “RoundRobin” command takes an initial optional integer argument specifying how many times each player should play his/her opponent consecutively (Stewart Holden). Added “BrowseLast” command. Long standing problem with reserved tables finally fixed (Stewart Holden). “ResultsByRound” command now also lists number of losses, in case of players missing games completely. Most report-generating commands have been rewritten for code clarity. “RoundRATings” and “RATings” rewritten for easier maintenance. Next player is shown where available even when ABSP ratings are in effect, but the player name is no longer ever shown (just the ID), to make room for a new column (overridden by “config no_show_last”) showing details of the last game, for the sake of player verification. “showWallChart” was displaying one too many rounds; it no longer does so (Stewart Holden, issue 34). “config board_stability” is ignored at the beginning of a session. (issue 35) “InitFontes” interacts correctly with “config reserved”. (issue 36). “config show_divname” forces division names to be displayed, even when there is only one division. “Addscore” command warns if an entered score is less than 100. “ChewPair” was overestimating the number of players in contention (issue 37).
3.170	Toronto LCT	“config flight_cap” will let you override the default top-flight cap of 4 * number-of-rounds-remaining in Chew Pairings. Added “ShowDivisionScoreCards” command for Stewart Holden. “config pair_page_break = 15” will force a page break after every 15 players in regular pairings. Added “CheckRoundScores” command for Ben Greenwood. Added “update-pix” command for Kath Mullholand. Added “config player_photos = 1” option for Kath Mullholand. Changed “config entry = 'absp'” option to “config entry = 'spread' ”for Stewart Holden. “config table_method = 'consecutive'” will assign one board per table, tables numbered beginning at 1 in the alphabetically first division, then continuing consecutively in each subsequent division (Stewart Holden). “classes A 3” in the configuration file will declare 3 subdivisions of equal size in Division A, for use in awarding class prizes (Stewart Holden). Configuration errors pause to let you see them, even on old Windows systems (Mauro Pratesi). Added “TRUNCATEROUNDS” command for Stewart Holden. Corrected “DELETEscore” command to work in a spread-entry environment for Stewart Holden. Added “TOTalScore” command for Stewart Holden.
3.160	2007 Dallas Open	tsh should complain once and revert to black-and-white rather than crash if something is seriously wrong with its colour environment tourney.pl -C works again TSH/Command modules can be anywhere in @::INC Major internal rewrite to support ongoing web interface development. Please be sure to do a dry run if you are using this release at a tournament. Default pairings will begin with one or more round robins if the number of rounds remaining to pair is greater than the number of players in a division. “config force_koth” will force a round of unrestricted KOTH at the end of default pairings. “config alpha_pair_page_break = 15” will force a page break after every 15 players. The “InitFontes” command will avoid assigning byes to top-rated players, will assign better-quality pairings in odd divisions, and will if you really want to let you use it in a division with only three players. Its board number assignment algorithm has also been substantially improved. Added “lifeg” extension field. “RATings” command automatically accounts for split ratings “config split1” is now deprecated.
3.150	Toronto Open	Removed spurious error message from “ShowPairings”, introduced in 3.140 when player photos are not found. Fixed “SUBMIT” command to actually work in non-debug mode. Cross-platform support for “config backup_directory”. Fixed “showWallChart” command so that it doesn't display cryptic messages when used with track_firsts turned off (Vince Castellano). Added “ShowManyPairings” command (Vince Castellano). Cleaned up generation of HTML files and indices. Cleaned up generation of CSCs. Added “config allow_gaps = 1” to permit leaving unassigned gaps in a CSC. This necessitated a small change in the .t file format and major changes through tsh. As a side benefit, the “InitFontes” command will work around partly paired initial rounds, as long as the number of partly-paired players needing opponents is even in each round. Fixed “Addscore” command, now checks correctly for things that don't look like scores. Rewrote contender detection code in“ChewPair” yet again. The new version takes into account all available game data, including that from partly scored rounds. Added experimental “PRiZes” command, which lists all prizes to be awarded. “ShowPairings” command lists all byes ahead of unpaired players. Added “config board_stability”, which tries to keep one player from each game at the same board.
3.140	2006 MWMST	“config port = 7777” enables a multiuser version with graphical user interface in the very early stages of development. The “part-of-name1,part-of-name2” syntax introduced in 3.110 works within “Addscore” Added hooks to “ShowPairings” to support display of player photos when available Use Term::ReadLine where available, so that you can scroll back instead of retyping commands. Fixed a semi-obscure bug in “ChewPair” that could affect top pairings at the end of a tournament: the primary criterion for choosing opponents is now whether or not they can catch up to the current leader. Added “SUBMIT” command to submit ratings data (currently only for NSA ratings, others added on request)
3.130	2006 BMSC	“RoundRobin” command balances starts and replies for groups sized 2-26 Corrected bug that might have sometimes led to incorrect assignment of starts and replies
3.120	2006 USSO	“FactorPair” command no longer does opponent availability optimisation. “ResultsByRound” command now also lists contestant ranks prior to start of selected range, to facilitate computing USSO "Best Record Day n by Player In Bottom Half" prizes. “TUFFluck” external command works with case-sensitive filesystems.
3.110	Saxon 2006	“config rating_system = 'nsa lct'” enables LCT ratings multipliers (for Wes Eddings) “LOOK” command works within “Addscore” “config entry = 'absp'” sets data entry to winner-loser-spread mode, generally suppresses display of raw game scores in favour of spread. “update-dict” external command fetches dictionary files, which are too big to be included in the regular distribution.
3.100	July 2006 Toronto	config autopair is slightly less finicky about format (Peter Keller). “LOOK” command now uses SOWPODS2003 and TWL2006 lexica. Spurious error messages generated when pairing odd divisions for multiple rounds (InitFontes, RoundRobin) are gone. An error message is displayed if no divisions are defined in the configuration file. tsh is much more tolerant of non-native line breaks in its configuration and data files. Using a configuration file marks it as modified, so that tsh will choose it the next time it is run. If you can't remember a player's number, you can enter it as “part-of-name1,part-of-name2”. For example, if “Chew, John” is the only person whose family name contains “CHE“, he can be referred to as “che,”. When division sizes were close to the number of rounds being played, it is easy for bottom-ranked players to clinch positions near the bottom and be relegated to playing each other for several rounds. Chew pairings now check for this condition and do not allow two players who have already played each other to be separated from a flight of contenders.
3.090	2006 Toronto LCT	A tournament can use default pairings for some divisions and automatic pairings for others.
3.080	BAT 2006	“config initial_schedule” specifies number of rounds of InitFontes pairings to use at start of default pairings If “config html_directory” does not exist and cannot be created, an error message says so. “ShowPairings” command shows table numbers in alpha mode, correctly handles byes in alpha mode. Added “util/multiroto” to report on rotisserie pools that span more than one tournament. Fixed a semi-obscure bug in “ChewPair”. When using pairings based on the second preceding round, the number of rounds used to compute the contender cap had been too large by one.
3.070	NSSC 2006	“RANDomscores” command now generates who goes first randomly to improve verisimilitude of reports on simulated runs
3.060	Toronto vs. Mississauga 2006	Added “exagony” configuration option. Added “TeamStandings” command “RATings” command correctly accounts for scoreless byes “STandings” command correctly accounts for scoreless byes
3.050	Dallas Open 2006	If you are using xterm terminal emulation and have specified the “event_name” configuration option, tsh will identify itself in your window title bar. “ShowscoreCard” formats correctly even when first and seconds are not assigned. Under some circumstances, the downloaded executable files would not be executable for OS/X users. I think I've fixed the problem, and documented how to fix it locally if it recurs. At Kath Mullholand's request, the “high-win” external command (and the other three similar ones) now display a header that identifies the division. Quality of pairings is slightly improved by disabling a speed optimization that tries to pair first those players with a smaller number of candidate opponents, when the number of players to be paired in a group is no more than twelve. At Mary Rhoades' request, the “ShowPairings” command now also generates alphabetical pairings listings in addition to the old rank-based listings. The “Addscore” no longer accepts scores outside the range [-150,1500]. Added “UPSETs” command to list top ratings upset games. The munge-scores.pl utility, used by several external and utility commands, now reports player numbers, so those external commands will report them too.
3.040	Oshawa 2006	Colour prompts for Windows users disabled by default, still optionally selectable. Windows colour is apparently broken in the most recent ActivePerl distribution. If an html_directory needs to be created, lib/tsh.css is copied into it. Fixed an obscure bug in “ChewPair” that made it occasionally crash. Utility command “util/truncate_t” is tolerant of blank lines. Added top-level script “get-tsh.pl”, built using “update” external command, to act as a standalone download tool for tsh. That is, you can if you want to download just this one script, run it and it will fetch everything else for you. Useful if you have a mostly complete installation but have somehow managed to wreck either your “tsh.pl” or part of the software update mechanism. The “update” external command was saying that some files had been updated even when no files had been updated. That bug is fixed.
3.030	WSC 2005	Support for scoreless byes. Fixed a bug that caused starts/replies to be instable. Fixed “ChewPair” command and pairing system: Gibson spread threshold now based on some historical data, leaders paired against lower-ranked contenders. “Addscore” won't let you switch to a division whose results have all been entered. “AUPAIR” command supports byes. Added “player_number_format” configuration option. Added “show_teams” configuration option. “RATings” command shows next opponent if paired. (Suggested by David Acton.) 0-point bye counts as a loss, not a tie. Fixed a bug where pairings display would stop if a table was unoccupied. Fixed a bug in bin/munge-scores that led to games with byes appearing in high/low win/loss lists. “MISSing” command lists players in current standing order. Tweaked code for reserved table assignments, think there might still be a problem. For a few versions, you had to specify the max_rounds configuration option to make pairings commands work. This should no longer be necessary, though it is still recommended.
3.020	Kingston 2005 ("Now... with tint control!")	All remaining commands converted to using newer parsing code. “LOOK” command checks for dictionary at runtime. “UnPairRound” command does not affect inactive players, minor bugs fixed. “EditScores” command deletes future byes when a player is (re)activated. “RANDomscores” command sets spread to 50 points for scheduled byes. Fixed a bug where if you asked for pairings too far in advance, inactive player records would still have byes added. Colour prompts for Windows users too. “MISSing” command ignores inactive players, displays board numbers when known. “ShowscoreCard” shows board numbers. “UPDATE” command will delete read-only files (like src/TSH/blib/lib/TSH/Pair.pm) to make way for their replacements. “Addscore” prevents entry of Rd. N+1 results when Rd. N is incomplete even when switching divisions. Several commands explicitly report when pairings have failed. Added “RandomPair” command. Added “team” extension field. Added “config initial_exagony” configuration parameter.
3.010	Kingston 2005	Added “ON” and “OFF” subcommands to“EditScore” to permit enabling and disabling a player. “ShowscoreCard” detects truncated .t files. “ShowscoreCard” reports nonstandard spreads for inactive players. Removed a bug that caused multiple byes to be appended each round to inactive players. Removed two bugs introduced in 3.000 that caused odd divisions to severely misbehave. Removed bug introduced in 3.000 that caused round robins to fail sometimes. UnPairRound command will delete scored byes if they are the only scores in round. RANDomscores command deals more appropriately with partially scored rounds, completing them rather than adding one score to each player regardless of number of scores recorded. Deprecated PartialSWiss command finally deleted. First sample folder cleaned up. RoundRobin command works with inactive players. In many places, the division name is now not displayed if the tournament has only one division. PAIR PairMany commands allows either player number to be zero for a bye. PAIR, PairMany commands un-pairs opponents of repaired players, assigning 50-point byes if necessary. KOTH, Pair1324 commands works with inactive players, uses consecutive repeat avoidance, matching starts and replies, minimizing repeats as secondary criteria. “FactorPair” command released.
3.000	MWMST 2005	Finished implementing “ChewPair” command and pairing system, which is now the default if pairings are asked for and no other system was specified. Added “HUH” command for explaining error messages. Rewrote “HELP” command to give detailed help about individual commands. Added “AUPAIR” command for exporting to that ratings file format. Many commands rewritten to conform to new internal code standards to support faster software updates and smaller runtime memory usage. Fixed a bug in “ShowPairings” which had caused it to omit boards where more than two players had erroneously been scheduled to play. Added “DEBUG” command for selectively toggling debugging on and off. “SWiss” command is now just an alias for “NewSwiss”. Added “config external_path” to allow user plug-in directories.
2.980	NSC 2005	“ResultsByRound” command creates printable HTML files. Added very experimental versions of “FactorPair1” and “FactorPair” commands. Added “config prize_bands” to expand support for Chew pairings. Added “config save_interval” to auto-save when entering a large number of scores. Added “config rating_system” to allow computation of ABSP tournament ratings in “rat” command. Added “maketm” external command to generate TourneyMan data files. Added “high-loss-round” external command to list high losses in each round. Added “high-win-round” external command to list high wins in each round. Added “util/parsetm” utility to import TourneyMan data files. “roto” allows any number of players per team. “showWallChart” syntax does not require “-f” before round number anymore. External command “show12” shows counts of firsts and seconds for each player. The board at which each game was played is recorded (in “etc board”) and will not change once assigned.
2.975	ABSP compatibility	Added “ABSPgrid” command. Added “config colour”. Made external commands work with Windows XP. Reorganized search algorithm for configuration files. It’s now (1) files or directories specified on the command line, (2) the most recently changed among */config.tsh and */tsh.config, or (3) tsh.config. The intent is that users should have one tsh directory with a subdirectory for each event. Added “update” external command, which downloads updates to the distribution.
2.960	Albany NY	Added “tuffluck” external command. Partly functional version of “ChewPair” command added. ScoreCard command generates HTML version that can be printed as replacement for lost scorecard. WallChart command generates HTML version. Round-by-round HTML files are automatically indexed. New RATING subcommand in EditScores. Contextual help in EditScores. EditScores can be used before any results are entered. Initial .t files may omit trailing semicolon.
2.950	Toronto LCT	Addscore prevents entry of Rd. N+1 results when Rd. N is incomplete. New external command “show12” displays table of firsts/seconds. First/second forecasts/assignments are now more accurate.
2.940	Stamford CT	Optional specification of configuration file on command line. NewSwiss tries to minimize repeat pairings.
2.930	CNSC 2005	Addscore reports how many scores remain unentered. Two-part tournaments are correctly split-rated.
2.920	Thunder Bay ON 2005	Added some more three-word names to tourney.pl.
2.910	BAT 2005	Added config gibson. Added config max_rounds. The timestamp of the most recent score entered for each player is now recorded. Added ROTO command. Code for reserved table assignments is working again. Forecasts of firsts and seconds are purged before new forecasts are generated, which addresses a potential problem with corrupt stale data when players have systematically misreported firsts and seconds. Added config no_text_files. Added config html_directory. Autopair supports PAIR1324. Fixed a bug that prevented calculation of the ratings of unrated players.
2.900	BAT 2005	Some errors now have numbers, which can be looked up in Troubleshooting..
2.850	NSSC 2005	Fixed a bug introduced to RoundStanding in 2.800 (?).
2.840	NSSC 2005	Fixed a bug introduced in 2.800 (?) where missing pairs were displayed twice.
2.830	NSSC 2005	Generated HTML is somewhat more legible and conformant.
2.820	NSSC 2005	Corrected determination of firsts and seconds.
2.810	NSSC 2005	Added external command (plug-in) interface Partial support for active/inactive players 'off' extension field in '.t' files MISSING and ShowPairings show "draws" if players must draw config name_format = "%-22s" config max_name_length = 22 config assign_firsts = 0 showWallChart and showScoreCard adjust column with to widest team name.
2.800	NSSC 2005	EditScore now displays the current scorecard before each prompt, rather than after changes. You can now enter the word first or second at the EditScore prompt to specify that the player went first or second. MISSING and ShowPairings display firsts and seconds if known. config track_firsts = 1 enables tracking of who went first or second in each game. tsh will use NSA rules for determining firsts and seconds, and complain if scores are not entered in order of play if known. Auto-pairing used to be available only when a division was completely unpaired. Now, you can still auto-pair even after entering a few manual pairings. You can now write config variable = value instead of perl $config'variable = value in tsh.config. Byes are automatically chosen and assigned by the NS, KOTHand Pair1324commands. The BYE command is now deprecated. It is no longer documented, and will be deactivated soon. Use the PAIR and Addscore commands instead. The ShowPairings command used to always list everyone and their opponent (if any). Now, if no players are paired, it says so rather than listing everyone as unpaired. The PAIR command used to always echo back the names and standings of the players you just (manually) paired. Now it only does so if you changed an existing pairing. The SWiss, PartialSWiss, PRESWiss and PrePreSWiss commands are now deprecated. They are no longer documented, and will be deactivated completely soon. Use NewSwiss instead. You can now enter 'es' when in Addscore mode, to go into EditScore on the most recently entered (and presumably mistaken) score. EditScore command sometimes didn’t correctly record changes when editing multiple divisions, does so now. UnPairRound command used to sometimes give incorrect error messages, but no longer does so. Pair1324 documentation used to say that below 4th place, pairings were KOTH. This is untrue (they continue 5-7, 6-8, etc.) and the documentation has been corrected. All command parsers rewritten to give consistent response and more specific descriptions of syntax errors. RoundStandings used to misreport results in the current round, if not all scores had been entered, now reports correctly. Division name may now be specified in command lines, even when event only has one division. Distribution now in ZIP format. Documentation rewritten. Randomization of player orderings is now much less random, so first-round table assignments stay stable unless roster is changed. Some spurious warning messages deleted. Support added for new generalized .t files. ShowPairings now generates HTML. Trailing commas in player names are suppressed.

2.000	MWMST 2003	MISSING lists missing data in score entry mode. Teed log files have '.doc' extension, no embedded spaces.
1.900	CWSCQT 2003	Added ShowPairings -p as kludge to work with make-rr.pl.
1.800	Albany 2003	ScoreCard shows opp ratings. UnPairRound reports on problem players. Table numbers can be arbitrary strings . Entering a division name changes divisions in score entry mode. ShowWallChart -f r lists beginning with round r only.
1.700	Boston 2003	EditScore added. NewSwiss code added, first manually paired player can be 0 for an unscored bye pairing.
1.600	Boston 2001	InitFontes works for any number of players, not just 4n and 4n+2.

59	new	medium	low	2007-08-28	open	Stewart Holden	MISSING should not require its round number unless “config allow_gaps = 1” is in effect.
60	new	medium	high	2007-08-28	open	Stewart Holden	It would be nice to be able to specify the order of rounds in a round robin, so that, e.g., players who needed byes in specific rounds could be accommodated.
61	new	medium	medium	2007-08-28	open	Stewart Holden	The order of rounds in a round robin ought to depend on the division name, so as to reduce the likelihood of data entry confusion.
66	new	medium	medium	2007-09-17	open	Stewart Holden	The stats command incorrectly reports a large number of start/reply errors when round robin pairings are used. This problem may be resolved as part of a planned rewrite of the round robin code, or may need to be specifically addressed.
67	new	high	high	2007-09-17	open	John Chew	The following situation might be an example calling for a change to the current Chew pairing algorithm. With a flight cap of 4, there are four contenders with more or less the same record. All pairs have played each other except 1-3 and 1-4. As things stand, because the four require one repeat to be paired, this is accepted as the repeat tolerance, the players are split after second place and paired 1-2, 3-4. Although it would be computationally prohibitive for large flights, it might be worth trying to minimize the total number of repeats for small flights like this to achieve 1-4, 2-3 pairings. Also, when the top two places are Gibson-equivalent, it is imperative that 1-2 not play each other if 3 or 4 are in contention.
69	new	low	high	2007-09-29	open	John Chew	In order to use tsh to look after Scrabble clubs, the following features are required and likely more: the chronological concatenation of sessions (each with its own ‘.t’ file) into seasons, where the output ratings from one session become the input ratings of the next and only one session is active at a time; overall season statistics including performance rating calculations; and something like Washington Go first-available pairings.
75	new	medium	low	2007-09-12	open	Stewart Holden	An extra page break appears after the value of config html_top” in the output of “ShowDivisionScoreCards”.
76	new	medium	high	2007-10-07	open	John Chew	More basic statistical research is required to determine the distribution of scores as a function of player ratings, start/reply and playing environment.
77	new	medium	high	2007-10-07	open	John Chew	The research of issue 76 needs to be applied to more accurately model possible future outcomes in Chew pairings.
78	new	medium	medium	2007-09-12	open	John Chew	The research of issue 76 needs to be applied to more accurately determine Gibsonization thresholds.
82	new	medium	low	2007-12-03	open	Jim Hughes	“config repeats{DIV}” should specify when repeats will be permitted.
83	new	medium	low	2007-12-03	open	Jim Hughes	The manual needs an index.
84	new	high	medium	2007-12-05	open	Jim Hughes	HTTP routines should use LWP where available.

88	new	medium	medium	2008-05-15	open	John Chew	It should not be too difficult to prepare a standalone Windows executable version of tsh, which would be helfpul for newbies but perhaps take up too much disk space for everyone else.
89	new	high	low	2008-05-15	open	Mauro Pratesi	Corrupt configuration file diagnostics may not be visible under Windows.
93	new	medium	low	2008-07-27	open	John Chew	Table reservation data belongs in “.t” files so that it can be edited using “EditScore”
94	new	medium	low	2008-08-24	open	John Chew	Trying to enter a bye score as something-0 should cause tsh to prompt you offering to rewrite the game as a forfeit.
95	new	medium	medium	2008-11-07	open	Sherrie Saint John	It would be nice to be able to print result slips with player names.
96	new	medium	medium	2009-04-19	open	Tim Fukawa-Connelly	You shouldn't have to enter bye scores by hand.
97	new	high	medium	2009-06-17	open	Andy Saunders	best possible finishes are overestimated when flight sizes are small.
98	new	low	medium	2009-07-20	open	John Chew	SUBMIT.pm needs to be rewritten along the lines of WebUpdate.pm to use Win32 code for compatibility with older XP systems.
99	new	low	medium	2010-06-19	open	Pakorn Nemitrmansuk	Player photos should show different facial expressions depending on recent W-L history or overall standing.
