    Pairfx

    Pairfx

    Chess pairing program for run through and round robin tournaments

    PairFX is a chess pairing program specialized for youth tournaments in schools and chess clubs . No installation required! Just Unzip it and go! I created a free online/mobile version as well : https://oks.myvcc.be/pairfx-live/ (You can run any kind of tournament with it actually but it was written for chess in schools) It supports the organization of a so-called 'run through' tournament and round robin (everybody against everybody) tournaments Swiss pairings are not (yet) possible. Are you a chess teacher at school, or organize a separate tournament at the club? Try PairFX! The run through pairing system makes it possible for player to come and go whenever they want and also to keep players playing all the time. It is not round based , so not everybody has to be finished to allow new pairings to be made. This is really great when players play at different speed and works very well in the club or at school.
