Deep Blue–Kasparov, 1996, Game 1 is a famous chess game in which a computer played against a human being. It was the first game played in the 1996 Deep Blue versus Garry Kasparov match, and the first time that a chess-playing computer defeated a reigning world champion under normal chess tournament conditions (in particular, standard time control; in this case 40 moves in two hours).
