New York (3), 30 January 2003

1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 e6 5.Nf3 Nbd7 6.Qc2 b6 [In the first game the move was 6...Bd6]
7.cxd5 exd5 8.Bd3 Be7 9.Bd2
Kasparov goes out of book moves. [9.0-0 0-0 10.Bd2 h6 11.Ne2 Bb7 12.Ng3 Re8 13.b4 Rc8 14.Bc3 Bd6 15.Nf5 Bb8 16.Nd2 c5 17.bxc5 bxc5 18.Qb2 Qc7 19.g3 c4 20.Be2 Nb6 21.Qc2 Qd7 22.a4 Bc6 23.a5 Na4 Akesson,R-Eriksson,J/Nkara 2002/CBM 91/0-1 (39)]
9...0-0 10.g4!?
Kasparov plays aggressively.
10...Nxg4 11.Rg1
the game is hard fought. [ 11.Bxh7+ Kh8 12.Bd3 was also possible.]
11...Ndf6!?
Deep Junior gets involved in complications which tend to favor a computer. [11...Ngf6 12.0-0-0 gives the initiative to White.]
12.h3 Nh6 13.e4! dxe4 14.Bxh6
[14.Bxe4!? Nxe4 15.Bxh6 Bf5 16.Rxg7+ Kh8 17.Nxe4 Qd5 18.Rg4!? with a very complicated position.]
14...exd3 15.Rxg7+
[15.Bxg7!? Ng4 ( 15...dxc2? 16.Bxf6+ Bg4 17.Rxg4# ) 16.Qxd3 Kxg7 17.hxg4 obviously did not please Kasparov]
15...Kh8 16.Qxd3 Rg8 17.Rxg8+ Nxg8 18.Bf4 f6
Black completely controls e5. A win is no longer achievable by Kasparov.
19.0-0-0 Bd6 20.Qe3!?
gives away the h3 pawn. [20.Bxd6 Qxd6 21.h4]
20...Bxf4 21.Qxf4 Bxh3 22.Rg1
[22.Nd2!? -- 23.Nde4]
22...Qb8 23.Qe3 Qd6 24.Nh4 Be6 25.Rh1 Rd8 26.Ng6+
White's attack seems dangerous, but Junior has everything under control.
26...Kg7 27.Nf4 Bf5 28.Nce2 Ne7 29.Ng3 Kh8 30.Nxf5 Nxf5 31.Qe4 Qd7
Now the game ought to end in a draw, but, under time pressure, Kasparov blunders.
32.Rh5?
Kasparov overlooks the mate threat at the 35th move. [32.Ng6+ Kg7 33.Nf4 Kh8 34.Ng6+=]
32...Nxd4! 33.Ng6+ Kg8 34.Ne7+ Kf8 35.Nd5
[Kasparov had planned 35.Rxh7, but overlooked the reply 35...Nb3+ 36.Kc2 ( 36.axb3 Qd1# ) 36...Na1+ 37.Kc3 Qd2+ 38.Kc4 b5+ 39.Kc5 Qd6#]
35...Qg7
[White hoped for 35...cxd5 36.Qxd4 ]
36.Qxd4 Rxd5
[ 36...Rxd5 37.Rxd5 cxd5 38.Qxd5 Qg5+ 39.Qd2 Qxd2+ 40.Kxd2 h5 and the advanced unopposed pawn on the h file wins, e.g.: 41.Ke3 Kf7 42.Kf4 Kg6 43.a3 b5 44.b3 a6 45.b4 Kh6 46.Kf5 Kg7 47.f3 Kh6 48.f4 ( 48.Kxf6 h4 49.f4 h3-+ ) 48...Kg7 49.Ke4 Kg6 50.Kd5 h4 51.Kc5 h3 52.Kb6 h2 53.Kxa6 h1Q-+ ] Kasparov resigns
