Heh.... "Crafty"ier cheats avoid all of the below because their modified Crafty is automated. ;) In general though, most of the cheats I have played had fairly constant move times, with a minumim of about 3 seconds per move. A long wait before a game starts is a poor indication of a cheater because many programs require a few seconds to initialize hash tables, load books, etc. for the first move. My program has spent as long as 25 seconds to play 1. e4 from its book. It then speeds up once it has booted IE from RAM. :) The biggest indication is a "human" who beats a computer > 2300 (FICS) at 3 0 more than twice in a row. Then you can apply Will's suggestion of checking the games for a lack of tactical blunders. James > I will >usually look at move-times using the smoves command on several games.
