World Chess Challenge Update

Start of World Chess Challenge 2006: First Match between Kramnik and Fritz Ends in a Draw

At the start of World Chess Challenge 2006, World Chess Champion Vladimir Kramnik (Russia) and the world's leading chess computer program, Deep Fritz (Germany), ended the first game in a draw after 47 moves. Kramnik (white) kept the pressure on the computer with a Catalan opening, and dominated the entire match. The World
Champion was obviously well prepared: He needed only 15 minutes for the first 20 moves, while Deep Fritz took three times as long. The two adversaries battled down to the last pawn. In the end, the computer managed to gain the
crucial half point against the World Champion. "I'm happy with the draw. It was a good start for this competition. I put the computer under pressure, but Deep Fritz mounted a precise defense," said the World Champion after the

The two opponents played before a full house at the hotly anticipated World Chess Challenge 2006 in the Federal Art Hall in Bonn. Dr. Werner Muller, Chairman of the Board of Management at RAG Aktiengesellschaft, the exclusive sponsor, and Peer Steinbruck, Federal Finance Minister and the patron of World Chess Challenge, made the opening move in the presence of Kirsan Ilyumzhinov, President of the World Chess Federation FIDE.

In Game 2 Kramnik overlooks mate in one!

Having benefited from the glaring error of Classical World Chess Champion Vladimir Kramnik of Russia, world's leading chess computer, Deep Fritz checkmated the rival in the second game and took the lead.

The six games in the duel between Vladimir Kramnik and Deep Fritz, the chess computer developed by Hamburg-based Chessbase, are held from November 25 to December 5, 2006. The venue is the National Art Gallery in Bonn, Germany. If Kramnik wins he will earn one million US dollars.

Kramnik played 3...b5 in the Queen's Gambit Accepted and equalized the chances with black by move 17, The key move of 18...c5 forced the white to fight for the comfortable position. Backed up by enormous calculating potential, Fritz created some tactical threats but Kramnik always kept things under control. The Russian could have made a draw several times, but he went on in hope of winning chances.

On move 33, Kramnik captured on c1, but that move contains a fatal error. Black's queenside pawns would still give him chances. Instead, Kramnik played the move 34...Qe3, having overlooked the mate in one to great pleasure of Fritz operators. It was one of the most unbelievable blunders ever seen at that level of chess and the first one in Kramnik's career.

Now 34...Kg8 35.Ng6 Bxb2 36.Qd5+ Kh7 37.Nf8+ Kh8 38.Ng6+ is the forced draw. But Kramnik played 34...Qe3?? The blunder of the century.

Game 3 is a Draw

World chess champion Vladimir Kramnik held computer program Deep Fritz to a draw Wednesday in the third game of the man vs. machine match.

Unlike the first two games, in which Kramnik outplayed the machine and obtained an advantage, the computer stood better for much of the time.

The computer now leads the six-game match 2-1 after Kramnik's colossal blunder in game two, in which he allowed a mate in one.

Kramnik, with the white pieces, again played the Catalan opening that he used in game one. In that game, he outplayed the computer and had a clear advantage. Former world champion Garry Kasparov claimed that Kramnik missed a win.

Kramnik varied from the first game on move seven. "Somewhere after move seven, something went wrong. I never had the advantage," he said afterward.

He added that he would have preferred the computer's position by move 14. Black had a mobile queenside pawn majority and Kramnik lagged slightly in development.

On move 21, the machine offered a pawn to maintain its initiative.

Fritz's advantage never got out of hand. "It was pretty drawish all the time but I had to defend carefully," Kramnik said, calling his position "unpleasant."

Kramnik quickly gave back his extra pawn and activated his pieces. The computer, meanwhile, converted its queenside majority into a passed a-pawn.

Kramnik then forced a draw by giving up his rook in exchange for Fritz's bishop and passed pawn. In the resulting endgame, Fritz had a rook and two pawns versus bishop and three pawns.

Despite Fritz's material advantage, this ending was easily drawn. The computer evaluated its position as being the equivalent of a pawn better.

"Obviously, that's too much in this particular position," said Fritz's operator Mathias Feist.

All Kramnik had to do was sit on the position and there was no way for Fritz to make any progress. Kramnik offered the draw and Feist accepted on the machine's behalf.
