X3D Fritz was a version of the Fritz chess program, which in November 2003 played a four-game Human–computer chess match against world number one Grandmaster Garry Kasparov. The match was tied 2–2, with X3D Fritz winning game 2, Kasparov winning game 3 and drawing games 1 and 4. ==Match conditions== Fritz ran on four Intel Pentium 4 Xeon CPUs at 2.8 GHz. The match was unique in how Kasparov relayed his moves to the computer. In most human–computer matches, the human makes their moves on a normal board, as in a normal game. These moves are fed into the computer by an intermediary seated where a normal human opponent would be, and its replies played on the board by the same person. In this match, however, no normal board and no intermediary was used. Instead, Kasparov, wearing special goggles, saw a three-dimensional projection of the board floating in the air in front of him. He spoke his moves out loud, thus conveying them to the computer which had a speech recognition system. The computer's replies were shown on the projected board. The time controls for each game were as follows: * Start with 120 minutes. * After move 40, add 60 minutes. * After move 60, add 15 minutes and 30 seconds per move. The match was held at the New York Athletic Club in New York City, USA. Kasparov got $150,000 USD for playing and an extra $25,000 for the drawn match. Kasparov would have earned an extra $50,000 instead if he had won. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「X3D Fritz」の詳細全文を読む スポンサード リンク
