The deciding sixth game of the 1997 rematch between world champion Garry Kasparov and IBM’s computer Deep Blue. The match stood at 2½–2½.
Kasparov chose the Caro-Kann and a dubious line, reasoning that an engine would not sacrifice a piece without a concrete gain. Deep Blue played the knight sacrifice 8. Nxe6 anyway, Black’s king was stuck in the centre, and Kasparov resigned after 19. c4 — the shortest game of either match.
Deep Blue won the match 3½–2½: the first time a computer had beaten a reigning world champion in a match under tournament conditions.
