In May 1997, IBM's supercomputer, called Deep Blue, beat Gary Kasparov, the great chess player from Russia, in New York. This was the first time a supercomputer had ever beaten a man in traditional chess, although men had often lost to computers when playing speed chess. In traditional chess, players have as much time as they want for their moves, but in speed chess their time is limited. The IBM computer is able to know between two and three million chess positions every second. It can make 100 billion moves in the time it takes a man to make one. The first time Kasparov played Deep Blue was in Philadelphia in 1996. Kasparov won that first match. In May 1997 there was a match again, and Deep Blue won. Deep Blue got 700,000 dollars for the game, and Kasparov took home 400,000 dollars. Now Kasparov wants to play a third match to decide who is the best player, but IBM says that Deep Blue has retired.
