We have a tournament on ICC every 6 months or so. Last one had 54 programs in it including Junior and Hiarcs. Crafty ran on a 4-way opteron and the actual game log files are available at ftp.cis.uab.edu/pub/hyatt/cct6.log They are labeled as log.rn where n is the round number, game.rn has the pgn for round n. the .po files are for the 4 playoff games to break the 3-way tie for first place between Crafty, Hiarcs and Zappa. > >> >>yes they are.
