The match was organized by the Association for Computing Machinery (ACM) to mark the 50th birthday of the first computer. The chief organizer was Monty Newborn, professor of computer science at McGill University and chairman of the ACM's Computer Chess Committee.

Deep Blue was an IBM RISC System/6000 Scalable Power Parallel System. It had 32 processors dedicated to calculation, each processor connected to 8 chess specific processors. It calculated 200.000.000 moves per second. That's about 100-200 times faster a nowadays (2007) average PC chess program calculates.

The hardware was installed at IBM's Thomas J. Watson Research Center, Yorktown Heights, state of New York, with a connection to Philadelphia via the Internet.

In February of 1996, Garry Kasparov and Deep Blue met for the first time in a best of six-games match. Although Kasparov had easily defeated Deep Blue's predecessor -- Deep Thought -- two years earlier, this match would prove to be one of the most difficult of the world champion's career.

After only the first game, Deep Blue made history by defeating Kasparov. Deep Blue's victory marked the first time that a current world champion had ever been beaten by a computer opponent under regular tournament conditions.

But Kasparov would not go down so easily. The world champion, known for his tenacity and his ferocious will to win, used his signature ability to switch strategies mid-game to take game two. Games three and four, although tightly contested, ended up in draws. Then, in game five, Kasparov again changed tactics mid-game to defeat Deep Blue. He needed no more than a draw in game six to win the match.

Kasparov won the final game in a Bobby Fischer teaches his nephew chess style, totally outplaying the computer and took the match by a score of 4 - 2. Citing the match as one of the most difficult of his career, Kasparov issued a rematch challenge for 1997, and IBM's Deep Blue team immediately accepted on Deep Blue's behalf.
