I am currently running a tournament for computers that play 10x8 Chess variants (Capablanca, Gothic etc.) There are currently 13 engines that can play this variant and support a standard protocol (so they can automatically play each other). As I will let engines play 8 games against each other (4 different initial setups, with both colors), and they get 25 min per game, the tourney will take about 2 weeks.
The games are broadcasted on line, and those interested in watching, can do so at:
