In November 2003, Garry Kasparov engaged in a four game match against chess playing computer program X3D Fritz (which was said to have an estimated rating of 2807), using a virtual board, 3D glasses and a speech recognition system. The first was a draw, X3D won the second after Kasparov blundered when short of time, Kasparov won the third, and the last game was a draw. The X3D Man-Machine World Chess Championship match ended in draw. Kasparov receives $175,000 for the result and takes home the golden trophy. (Although since it drew the match X3D Fritz said it was going to store a virtual reality copy of the trophy for itself.). Kasparov continued to criticize the blunder in the second game that cost him a crucial point. He felt that he had outplayed the machine overall and played well. "I only made one mistake but unfortunately that one mistake lost the game."
