On February 17, 1996, he completed one of the most famous chess matches between man and computer, a man’s victory. It was a glorious duel of supercomputer IBM Deep Blue against chess champion Garry Kasparov. Kasparov was the reigning world chess champion (the so-called classic world champion) at the time. By the way, Kasparov is certainly one of the strongest players in the recorded history of chess competitions, by some he might even be the strongest.
The Deep Blue and Kasparov computer duel took place in the US city of Philadelphia. A total of 6 games have been played. In the first game, Kasparov lost, which was the first time in history that a computer had defeated a reigning world chess champion under normal chess tournament conditions.
The Deep Blue computer was developed at IBM just for use in chess. It could count about 100 million strokes per second. Despite all this, Garry Kasparov beat him after 6 games played with a score of 4 – 2 (he won 3 games, lost only one and two were unresolved).
The following year (1997), there was again a Kasparov duel with the computer, but with an upgraded version of IBM Deep Blue. The computer could now count 200 million strokes per second and beat Kaspar by a score of 3.5 – 2.5.
