February 17th 1996; in the final game of a six-game match, world chess champion Garry Kasparov triumphs over Deep Blue, IBM’s chess-playing computer, and wins the match, 4-2. However, Deep Blue goes on to defeat Kasparov in a heavily publicized rematch the following year.

The six-game match between Kasparov and Deep Blue began on February 10, 1996, at the Pennsylvania Convention Centre in Philadelphia. Although Deep Blue was capable of evaluating 100 million different chess positions per second, the IBM team weren’t sure how the computer would perform in competition and Kasparov was favoured to win. Instead, much to his frustration, the world chess champ lost the first game to Deep Blue. However, the tenacious, brilliant Kasparov quickly staged a comeback and won the second game. The third and fourth games ended in a draw, while Kasparov won the fifth game. On February 17, the human chess master triumphed over Deep Blue in the sixth game and took the match, with a final score of 4-2.
