Deep Blue IBM developers Murray Campbell (left) and chess grandmaster Joel Benjamin (right) working on programming Deep Blue to play chess openings. This machine was a successor to two earlier projects dating from 1985 (ChipTest and then Deep Thought). The Deep Blue prototype played in the 8th World Computer Chess Championship in 1995. This was followed by two matches against the World Chess Champion Garry Kasparov. In the first match, in 1996, Deep Blue won a game but lost the match. In the second match, in 1997, Deep Blue made history by defeating Kasparov, the first time a computer had defeated a reigning world champion at standard time controls. Deep Blue mainly used brute force computing, calculating 200 million positions per second to a depth of many moves. See image C033/7702 for more members of the IBM team.
