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)...
