Game 4 drawn in 27 moves. The match is over at 2-2
History was repeated once again as this match ended up without a winner. In the 4th game the "mechanical chess beast" Fritz was very well prepared and programmed and made an opening which Kasparov knew very well since he has played it many times in the past.

The Russian champion escaped easily all traps, and played very precisely disarming Fritz little by little. The draw came as a reasonable result of the game and finally of the whole match thus giving us the impression that this battle between man and machine isn't over yet.
After all, Kasparov stated recently that "machines have still a lot to learn from men..."

Kasparov crushes x3d Fritz in game three to tie the match
X3D Fritz looked completely confused almost from the beginning. The opening moves of the game created a closed position with very little active play for the powerful pieces. In such positions the human ability to make long-term plans becomes far more effective than the machine's ability to calculate variations.

Chess programs like X3D Fritz look at each position and evaluate the best move by looking as deeply into the future as they can. A powerhouse like X3D Fritz running on an Intel quad Xeon 2.8 GHz machine like this one can "see" as deeply as 20 ply, or half-moves in a few minutes by searching over four million moves per second.

(We say "half-move" because in chess notation we record each pair of white-black moves as one move. E.g. 1.Nf3 Nf6 2.c4 e6 is two moves, but four ply or half-moves when considering how far ahead a computer is looking.)

Despite that incredible power, this is only a dent in the depth and breadth of the game of chess. In a typical middlegame position there might be 20 possible moves for one side. Then the other side will have 20, then the other side another 20... You can see that the number of possibilities quickly grows into the hundreds of millions. Of course most of these moves won't be good ones, so X3D Fritz's intelligent program sifts out the best lines and focuses on those. Read more >>>

X3D Fritz wins game two after Kasparov blunder

Nov. 13, 2003 (from the official website) Internet commentator Mig Greengard immediately typed out "Kasparov has blundered!" to the hundreds of thousands of online viewers around the world. In his hurry to make the final moves to the time control Kasparov had overlooked a relatively simple pin tactic that allowed X3D Fritz to play a crushing attacking move with 33.Rxe5 in the diagrammed position.

The rook on f8 is unprotected so X3D Fritz gained won a pawn and gained a dominating position after 33...dxe5 34.Qxf8 Nd4 35.Bxd4 exd4 36.Re8 Rg8 37.Qe7+ Rg7 38.Qd8 Rg8 39.Qd7+

Kasparov himself was aware of his tragic error almost immediately. With no opponent to hide his frustration from he got up from the board shaking his head in anger. He stormed around the room, waiting for X3D Fritz to deliver the deadly blow he knew was coming. He didn't have to wait long.

A few moves later it was clear that it was indeed as bad as we had thought. A rattled and defeated Kasparov played on listlessly in a position that at first a few commentators thought might hold out chances for a draw. But it was exactly the sort of tactical attacking position that computer play perfectly, so the loss of a pawn was the least of Kasparov's problems. His king came under a direct attack by X3D Fritz's queen and rook and the end was near.

Kasparov resigned on move 39. What he had already seen was now painfully obvious. X3D Fritz would grab more pawns and push them down the board where they would promote to new queens. It was hopeless. After over three hours of close battle Kasparov had slipped just once and was punished mercilessly by the machine.

X3D Fritz holds Kasparov to a draw in first game

Nov.11, 2003 The first game of the Man-Machine World Chess Championship was a thrilling 37-move draw that kept the fans on the edge of their seats from the very first moves. Both man and machine played aggressive chess with none of the caution many expected in this initial encounter. After one game the match is tied, 0.5-0.5. X3D Fritz will have the white pieces in game two on Thursday.

Kasparov had a slight advantage and was looking for more when X3D Fritz grabbed a pawn to put more pressure on the world #1. Kasparov sweated while his clock ticked down to 10 minutes and he couldn't find anything better than to allow X3D Fritz to force a draw by repetition of position.

The machine couldn't see any advantage for itself and accepted the tacit offer by repeating the position to draw the game on move 37, three moves before the time control at move 40 when the players would get another hour. In the final position Kasparov had a rook for a bishop and two pawns, which is generally considered material equality.
