Kasparov,G (2830) - X3D Fritz [D45]
Man-Machine World Championship
New York City USA (Game 3), 16.11.2003
1.Nf3 Nf6 2.c4 e6 3.Nc3 d5 4.d4 c6 5.e3 a6 (D1)
Diverging from game one, when the more common 5...Nbd7 was played. This sideline of the Slav with 5...a6 was criticized by Kasparov after the game. From the continuation here we can see why.
X3D Fritz is playing from its opening book right into a position it doesn't understand at all! When Kasparov said this everyone looked over at poor Alex Kure, the man responsible for selecting and "training" X3D Fritz's openings.
Kasparov has little practical experience with this sideline and in both cases (once with white and once with black) the game continued with 6.b3.
When this move appeared on the screen I thought maybe the Fritz team were trying to give Kasparov a little psychological jab. He played this move himself a month ago against Huzman in a game that turned into the shortest loss of his career after a horrific blunder. They wouldn't admit it, but you know they knew about that game and that Kasparov would be forced to think about while he was sitting there against X3D Fritz.
6.c5 Nbd7 7.b4 a5 8.b5 e5 [8...Ne4? 9.Nxe4 dxe4 10.Nd2 f5 11.f3 Qh4+? (11...exf3 12.Qxf3+/-) 12.g3 Qh6 13.Qe2 1-0 Euwe,M-Alekhine,A/NLD 1935/(41); >=8...e5]
9.Qa4! Given an exclamation point by Gligoric and Wade in their book "The World Chess Championship" (1972). This move was apparently not in X3D Fritz's opening book so it was now on its own.
9...Qc7 10.Ba3 [10.Be2 e4 11.Nd2 g6 12.Nb3 Bh6 13.Bd2 0-0 14.0-0-0 b6 15.bxc6 Nb8 16.cxb6 Qxb6 17.Qb5 Qxc6 18.Qxc6 Nxc6 19.Na4 1-0 Pachman,L-Fichtl,J/Prague 1954/MCD (41)]
10...e4 11.Nd2 Be7 All of these moves had been played before, although Kasparov said afterwards that he was not conscious of that at the time at this point. The game they are following was not a minor one, but a battle from the world championship match-tournament in 1948 between American Samuel Reshevsky and Soviet (Estonian) Paul Keres.
12.b6 Immediately sealing the queenside and diverging from that game from 1948, although there are still many similarities. A player as strong as Keres had no difficulty in seeing that Black needs immediate pawn play on the kingside in order to compensate for White's advantage on the kingside. He played a rapid ...h5 push and entered a very sharp battle.
[12.Be2 h5 13.b6 Qd8 14.h3 Nf8 15.0-0-0 Ne6 16.Ndxe4 Nxe4 (16...dxe4 17.d5 Bxc5 (17...0-0 18.dxe6 Qe8) 18.dxc6 Bxa3+ 19.Kc2) 17.Nxe4 h4 0-1 Reshevsky,S-Keres,P/NLD/URS 1948/MainBase (63) (17...dxe4 18.d5) ]
12...Qd8 13.h3 An odd little prophylactic move that shows that Kasparov is betting that X3D Fritz won't know what to do in this position without any clear targets for its pieces.
All the time Kasparov spent training with X3D Fritz clearly paid off. 13.h3 doesn't develop anything but it takes away a square from Black's knight, the g4 square.
13...0-0 14.Nb3 (D2)
