text: Deep Fritz match Kramnik played a six-game match against the computer program Deep Fritz in Bonn, Germany, from 25 November to 5 December 2006, losing 2–4 to the machine, with 2 losses and 4 draws. He received 500,000 Euros for playing and would have received twice as much had he won the match. Deep Fritz version 10 ran on a computer containing two Intel Core 2 Duo CPUs. Kramnik received a copy of the program in mid-October for testing, but the final version included an updated opening book. Except for limited updates to the opening book, the program was not allowed to be changed during the course of the match. The endgame tablebases used by the program were restricted to five pieces even though a complete six-piece tablebase was widely available.
  The first game ended in a draw. A number of commentators claimed that Kramnik missed a win. The second game was won by Deep Fritz due to a mistake by Kramnik, who failed to defend against a threatened mate-in-one. Susan Polgar called it the "blunder of the century". The third, fourth and fifth games of the match ended in draws. In the last game, Kramnik played the aggressive Sicilian Defense in an attempt to win with black and hence even the match, but he was outplayed by Fritz. Kramnik was forced to resign, and Fritz won the match 4–2.
  this has turned out to be the last major human–computer match in classical format. According to one expert at the time, "I don't know what one could get out of [a further match] at this point. The science is done."
  Personal life
  On 30 December 2006 Kramnik married French journalist Marie-Laure Germon. Their wedding took place in the Alexander Nevsky Cathedral in Paris. They have two children: daughter Daria, and son Vadim Vladimirovich. They reside in Geneva.
