Deep Blue versus Kasparov, 1997, Game 6
Game 6 of the Deep Blue–Kasparov rematch, played in New York City on 11 May 1997 and starting at 3:00 p.m. EDT, was the final chess game in the 1997 rematch between Deep Blue and Garry Kasparov.
Deep Blue had been further upgraded from the previous year's match 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, and drawn games three, four, and five.
The loss marked the first time that a computer had defeated a reigning World Champion in a match of several games. The fact that Kasparov had lasted only 19 moves in a game lasting barely more than an hour attracted considerable media attention.
