As early as 1845, Charles Babbage proposed programming his invention, the Analytical Engine, to play chess. A hundred years later, computer science pioneer Claude Shannon thought that a chess-playing computer could lead to other uses. In 1989, world chess champ Garry Kasparov beat Deep Thought, a computer programmed at Carnegie Mellon University. Seven years later, Kasparov won against IBM's DeepBlue. But in 1997, Deep Blue won. The computer's parallel processing technology could analyze 200 million positions every second. Kasparov was fast, but not that fast!
