1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.d4 Bg4 10.Be3 [The other main line is 10.d5 Na5 11.Bc2 In the XI World Championship, Zaitsev-Sande, there followed: 11...Qc8 12.a4 c6 13.Bg5 h6 14.Bxf6 Bxf6 15.dxc6 Bxf3?! (15...Rd8 16.axb5 axb5 17.Qd5 Qxc6 18.Bd3 Qxd5 19.exd5 Nb3= Tseshkovsky-Romanishin, Tallinn, 1979, is ECO.) 16.Qxf3 Qxc6 17.Rd1 Be7 18.Nd2 Nc4 19.Nxc4 bxc4 20.a5 and White exploited the "OCB" syndrome to perfection.]

10...exd4 11.cxd4 Na5 [11...d5 12.e5 Ne4 13.h3 Bh5 14.g4 Bg6 15.Nh2!? Bb4 16.f3 Bxe1 17.Qxe1 Ng5 18.Nc3 Ne6! 19.Rd1 Nb4 20.Qe2 a5 21.Qxb5 c6 22.Qe2 f5! produced a fine win for Black in Helbich-Marczell, 21st Czech CC Championship.]

12.Bc2 c5 13.dxc5 dxc5 14.Nbd2 Nc6 [In Stern-Penrose, Nielsen Memorial, Black preferred: 14...Nd7 allowing Stern's favourite 15.h3 Bh5 16.g4 Bg6 17.Nh2 but after 17...Qc7 18.f4 f6 19.Ndf3 c4 20.Nh4 Rad8 the World No.1 was master of the situation.; Gulko-Adams, Groningen, 1991, continued: 14...Nd7 15.Bf4! Re8 16.e5 Nf8 17.Be4 Rc8 18.Nf1 Ne6 19.Bg3 Nd4 20.Ne3 1-0 in 43.]

15.Qb1!? [Gulko-Portisch, Niksic, 1978, went: 15.Rc1 Nb4 16.Bb1 Rc8 17.h3 Be6 18.Nb3! Qb6 19.Ng5 Rfd8 20.Qf3+/- 1-0 in 36.]

15...h6 [Despite the fact that ECO shows: 15...Qc7 16.h3 Bh5 17.Nh4 Bd6! ]

16.e5 Nd5 17.Bh7+ Kh8 18.Bf5 Bxf5 19.Qxf5 Qc8 20.Qe4 Nxe3 21.Rxe3 Qe6 22.a4 Rfd8 23.Nf1 Rac8 24.axb5 axb5 25.Ng3 c4 With bishop v knight and a q-side majority, it looks good for Black.

26.Ne2 Qd5 27.Qb1 Qd7 28.Nf4 Nd4 29.e6 This fails to create any insoluble problems for Black.

29...Nxf3+ 30.Rxf3 fxe6 31.Ng6+ Kg8 32.Ne5 Qd2! 33.h3 Obviously his queen can't go anywhere.

33...Rd5 34.Re3 Rf8 35.Nf3 Qb4 36.Rxe6 Bf6 37.Qe4 Rdd8 38.Rb1 Qc5 39.Ne5 Qd5 40.Ng4 Qxe4 0-1
