A software bug helped Deep Blue psych Kasparov out


This is IBM’s Jeopardy playing robot Watson, not Deep Blue

The story of how computers surpassed human chess players, never to be caught again, goes like this: Kasparov beats IBM’s chess-playing supercomputer Deep Blue in 1996. In 1997, however, Deep Blue beats Kasparov during the six-game rematch. The 44th move during the first game of the rematch, Deep Blue moved a rook in a way that deeply concerned Kasparov. Kasparov didn’t understand the purpose behind the move, and came to the conclusion that Deep Blue was playing at a higher level than him. Surprisingly, the rook move was due to a software glitch, a IBM programmer relates in Nate Silver’s new book “The Signal and the Noise.”

The moment when computers surpassed human players at chess will likely be taken as a landmark moment in the history of artificial intelligence. It’s ironic, then, that one of the most important moves during the two series was directly due to a software glitch, again highlighting the differences between human intelligence and artificial intelligence: humans can lose themselves in their heads (Bobby Fischer comes to mind), but computers are always at the mercy of their coded DNA, which almost always includes bugs.

Take a look at the entire game in question below.
