Chess Engines Grand Tournament

Chess Engines Grand Tournament, also known as CEGT, is an organization that tests computer chess software by playing chess engines against one another and publishing a ratings table.

CEGT routinely tests chess engines in various time controls such as 40/4 (40 moves in 4 minutes, repeating), 40/20 (40 moves in 20 minutes, repeating), and 40/120 (40 moves in 120 minutes, repeating). The 40/120 matches are one of the best computer-chess games freely available online.

Heinz van Kempen co-ordinates a nine-member team. The team has run more than 480,000 games for 40/20, and more than 750,000 games for 40/4 (Blitz). Games include SMP testing.
