Deep Blue (chess computer) employed custom VLSI chips to execute the alpha-beta search algorithm in parallel, an example of GOFAI (Good Old-Fashioned Artificial Intelligence) rather than of deep learning which would come a decade later. It was a brute force approach, and one of its developers even disclaimed that it was artificial intelligence at all. Deep Blue and Kasparov played each other on two occasions. The first match began on 10 February 1996, in which Deep Blue became the first machine to win a chess game against a reigning world champion (Garry Kasparov) under regular time controls. However, Kasparov won three and drew two
Human–computer chess matches Michael Adams 5½–½ in a six-game match. While Adams was criticized for not preparing as well as Kasparov and Kramnik had, some commentators saw this as heralding the end of human-computer matches. Kramnik, then still the World Champion, played a six-game match against the computer program Deep Fritz in Bonn, Germany from November 25 to December 5, 2006, losing 4–2 to the machine, with two losses and four draws. He received 500,000 Euros for playing and would have received another 500,000 Euros had he won the match. Deep Fritz version 10 ran on a computer containing two Intel Xeon CPUs
