Deep Blue versus Kasparov, 1997, Game 6

Game 6 of the Deep Blue–Kasparov rematch, played in New York City on May 11, 1997 and starting at 3:00 p.m. EDT, was the last chess game in the 1997 rematch of Deep Blue versus Garry Kasparov.
Deep Blue had been further strengthened from the previous year's match with Kasparov and was unofficially nicknamed "Deeper Blue". Before this game the score was tied at 2½–2½: Kasparov had won the first game, lost the second game, and drawn games 3, 4, and 5 (after having advantageous positions in all three).
The loss marked the first time that a computer had defeated a World Champion in a match of several games. This, as well as the fact that Kasparov had lasted only 19 moves in a game lasting barely more than an hour, attracted much media attention.

After the game Kasparov accused the Deep Blue team of cheating (i.e. having a team of human masters to aid the computer). Although Kasparov wanted another rematch, IBM declined and ended their Deep Blue program.
