Deep Blue beats Kasparov

Deep Blue beats Kasparov

On May 11, 1997, IBM’s supercomputer Deep Blue makes chess history by defeating Gary Kasparov, the chess champion widely regarded as the greatest who has ever lived. The Russian master conceded defeat after 19 moves in the sixth game of the tournament, losing the match 2.5 to 3.5. It was the first defeat of a reigning world champion by a machine in tournament play. Big Blue, which can analyze 200 million chess moves a second, had met Kasparov once before, but the human held his own against the machine. Before their second meeting, Kasparov had never lost a professional chess match.
