Deep Blue vs Kasparov: 7 Stunning Moments From 1997
On May 11, 1997, Deep Blue vs Kasparov ended in a way nobody outside IBM thought possible. Garry Kasparov, the most dominant world chess champion of the modern era, resigned a game after only 19 moves against an IBM supercomputer, handing Deep Blue a 3.5–2.5 series victory in the Equitable Center in New York. It was the first time a reigning world champion had ever lost a match to a machine under standard tournament time controls, and the headlines the next morning treated it less like a chess result and more like a moment of historic surrender — the day human intuition got out-calculated in public.
Deep Blue vs Kasparov: How the May 11, 1997 Match Ended
The deciding game of the Deep Blue vs Kasparov rematch began at 3:00 p.m. EDT on Sunday, May 11, 1997, with the six-game series tied 2.5–2.5. Kasparov played the Caro–Kann Defense — a normally safe, solid opening choice — but allowed an early knight sacrifice that locked his king on its starting square and crushed his coordination. Within about an hour of play, after only 19 moves, he tipped his king and walked out of the room. For the first time in his professional career, Kasparov had resigned a match game without putting up a real fight.
The room at the Equitable Center went silent, then erupted. Spectators who had been watching the live broadcast on bulky CRT monitors in the auditorium below realized in real time that they were watching the door close on one era of human dominance and the door open on another. The match score was final: Deep Blue 3.5, Kasparov 2.5.
