PairFX is free and open source. It is my gift to the chess community. (Woehoe, my life is not wasted! I shall live on forever!)

Nevertheless, it is beer licensed ! If I ever get to your club, and you use PairFX. You should buy me a beer (and a good one as well, I live in Belgium so I know what good beer tastes like!).
You can use the source code, but you may never use it to create a product that is not free.

Although it might look simple, PairFX has already been months of evening and weekend work (thank your god I have a good and patient wife !)

If you appreciate my work, consider buying me a beer with the button below. Thanks a lot!
