1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Nf3 Be7 5.Bg5 Nbd7 6.e3 0-0 7.Rc1 c6 8.Bd3 a6 9.cxd5 exd5 10.Qc2 Re8 11.0-0 Nf8 12.Ne5 Ng4 13.Bxe7 Qxe7 14.Nxg4 Bxg4 15.Ne2 [15.Na4 had been played in Horowitz-Kashdan, US Championship 1938. These days White usually plays a rook to e1.]

15...Rad8 16.Ng3 Rd6 17.Rfe1 Qh4 18.b4 Rh6 19.Nf1?
[Too passive. 19.h3 seems safe enough for White, since 19...Bxh3?! 20.gxh3 Qxh3 21.Bf5 Qh2+ 22.Kf1 doesn't lead anywhere.]

19...Ne6 20.a4
[Instructional manuals sometimes advise us not to weaken our pawns in front of our castled kings but Black now demonstrates that the pawns can be disrupted via a direct attack here.] DIAGRAM

20...Bf3! 21.Be2
[21.gxf3 Ng5 22.Bf5 is White's best chance: (22.Qe2 Qh3! wins) 22...Nxf3+ 23.Kg2 Nxh2 24.f4!? g6 seems to win for Black]

21...Be4 22.Qd2 Ng5 23.f3
[23.Bd1 Bxg2! 24.Kxg2 Ree6! gives Black an unstoppable attack.]

23...Nh3+! 24.gxh3 Rg6+ 25.Ng3 Rxg3+! 26.hxg3 Qxg3+ 27.Kf1 Qxh3+ 28.Kg1 Qg3+
[28...Re6 29.Bf1 Rg6+ 30.Bg2 Bxf3 is another win.]

29.Kf1 Qh2 30.fxe4 Re6 31.Qd1 dxe4 32.Rc2 Qh3+
[32...Qg3 is simpler.]

33.Kg1 Rg6+ 34.Bg4 Rxg4+ 35.Qxg4 Qxg4+ 36.Rg2 Qf5 37.Rb2 h6 38.b5 c5 39.Rf2 Qg5+ 40.Rg2 Qd5 0-1
