ToMaChess is a gui application to manage chess tournaments written in Python.
The most recent release can be downloaded at Releases.
There are currently six tournament modes available: Swiss, Round Robin, Knockout, Keizer, Scheveningen and Custom.
Swiss uses the Dutch System implementation from bbpPairings to pair the rounds.
Parameters: Rounds, Pairings (First Round), Top Seed (First Round), Point System, Half-Point Bye, Baku Acceleration and Tiebreak (1) - (4).
Round Robin pairs the rounds by the Circle or Berger method.
Parameters: Cycles, Pairing Method, Custom Seeding, Point System and Tiebreak (1) - (4).
Knockout (Single-elimination) pairs rounds by the specified pairing method but, in successive rounds, only pairs the winners of the previous round. Furthermore, if there is a tie after the number of games specified, the specified number of tiebreak games will be played until either the tie is resolved or the number of tiebreaks specified in the Armageddon parameter is reached.
Parameters: Games per Match, Games per Tiebreak, Pairing Method and Armageddon.
Multiple Knockout (Double-elimination, Triple-elimination, ...) consists of multiple Knockout tournaments called 'Brackets' where players drop down to the bracket below their current one after losing.
Parameters: Multiplicity, With Finals, Games per Match, Games per Tiebreak, Pairing Method and Armageddon.
Keizer pairs rounds according to the Keizer system or at least according to the information I was able to find on how it is supposed to work.
Parameters: Rounds, Ratio (First to Last), Score for Byes (%), No Pairing Repeats, Points System and Tiebreak (1) - (2).
Scheveningen pairs rounds according to the Scheveningen system. More specifically the exact pairing system is inspired by the one developed by Richard Furness as described in this document.
Parameters: Cycles, Point System and Tiebreak (1) - (2).
Custom does not pair by itself at all, instead the user can manually pair all games of all rounds.
Parameters: Games per Round, Rounds, Point System, Half-Point Bye and Tiebreak (1) - (4).
The available tiebreak criteria are
- Buchholz (with additional parameters Cut (bottom), Cut (top) and Virtual Opponents)
- Buchholz Sum (with additional parameters Cut (bottom), Cut (top) and Virtual Opponents)
- Sonneborn-Berger (with additional parameters Cut (bottom), Cut (top) and Virtual Opponents)
- Games
- Games as Black
- Wins (with additional parameter Include Forfeits)
- Wins as Black (with additional parameter Include Forfeits)
- Average Rating (with additional parameters Cut (bottom), Cut (top) and Include Forfeits)
- Progressive Scores (with additional parameters Cut (bottom) and Cut (top))
- Koya System (with additional parameter Threshold (%))
- Direct Encounter
For the Armageddon parameter the user can specify additional parameters With Armageddon, After Tiebreak and Color Determination (In Order, Random or Choice).
Players can be manually added. Additionally, one can use various rating lists after downloading them through the rating lists window in the settings.
Teams are ordered sets of players. One can add players to a team, remove players from a team and change the lineup.
Team tournaments work much like regular tournaments, except for some restrictions and changes e.g. for tiebreaks or Armageddon.
There is an additional parameter Boards which specifies on how many boards the matches are played and there are two tiebreak criteria exclusive to team tournaments: Board Points and Berliner Wertung.
It is also possible to combine multiple tournaments to a multi-stage tournament.
A multi-stage tournament consists of a first stage with a number of tournaments where the participants are predetermined. On top of that, it has an arbitrary number of further stages where the participants of the stage tournaments are the participants that got a certain placement in a certain tournament of the previous stage.
For example one could have Round Robin tournaments Group A up to Group H with four players each in the first stage and then in the second stage a Knockout tournament Finals with all participants who placed first or second in their respective group.
If the option Draw Lots in Case of Tie is disabled, it is also possible to create a regular tournament with play-offs in case of a tie for first place. This can be achieved by creating a multi-stage tournament with only the desired regular tournament as the first stage and a Knockout tournament with only the first place as a participant as a second stage.
Tournament standings, pairings and results can be automtically exported as pdf files by specifying PDF Output Path in the settings.
Similarly, one can configure Server Address, Server Username and Server Password to automatically export tournament data in form of html files to an FTP-server.
