Deep Blue (chess computer)

Deep Blue was a chess-playing computer developed by IBM that gained fame for its matches against world chess champion Garry Kasparov in the 1990s. Originally known as Deep Thought, the project evolved into Deep Blue, which became the first computer system to defeat a reigning world champion in a match under standard chess tournament conditions. The most notable event occurred in May 1997 when Deep Blue played a six-game match against Kasparov.
