D86 Gruenfeld Defense Exchange Variation

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bc4 0-0 8.Ne2 Nd7 [8...c5 followed by ...Nc6, putting pressure against d4, is thematic and best. (J. Moldovan)]

9.0-0 e5?N [>=9...c5 ]

10.Be3 [10.Ba3 is superior.]

10...Nf6 11.f3 [11.dxe5 may be better. I had many opportunites to play this move, but never did.]

11...Be6? 12.Bxe6 fxe6 13.Qb3 Qe8 14.Qxb7 Rb8 15.Qxa7 Rb2 16.Ng3 Qa6 may be better.

16...Qb5 17.Qxc7 Nh5 18.a4? [18.Nxh5 gxh5 19.c4 gives White a big advantage.]

18...Qd3 19.Bf2 Nf4 Threatening 20...Nxg2 20 Kxg2 Qxf3+ 21 Kh3 (21.Kg1 Rxf2 22 Rxf2 Qxf2+ winning for Black.) h5, with a probable draw.

20...Nh3+? 21.gxh3 Qxf3 22.Nh1! The defense Black did not see.

22...Qxh3 23.Rb1 This forces a pair of Rs off the board, easing the task for the defender.

23...Qg4+ 24.Ng3 White still has to defend well here or he could get into trouble.

24...Rxb1 25.Rxb1 Qf3 26.Rf1 exd4 27.Bxd4 Bxd4+ 28.cxd4 Qe3+ Now my king takes a long walk across the board.

29.Kg2 Rxf1 30.Kxf1 Qd3+ 31.Kg2 Qd2+ 32.Kf3 Qd1+ 33.Kf4 Qd2+ 34.Ke5 Qg5+ 35.Kd6 Qf4+ 36.Kc6 Qc1+ 37.Kd7 Black finally runs out of checks.

37...Qh6 38.Qd8+ Kf7 39.Qe7+ Kg8 40.Qxe6+ Kg7 41.Ke8 [41.Nf5+ gxf5 42.Qxh6+ also wins.]

41...Qf4 42.Qe5+ Qxe5+ 43.dxe5 Black resigns 1-0
