1.e4 c5 2.Nf3 d6 3.Bb5+ Nd7 4.d4 a6 [4...Ngf6 is much more common, and after 5.Nc3 a6 6.Bxd7+ Black takes with the knight instead: 6...Nxd7 ]
5.Bxd7+ Bxd7 6.dxc5 [6.0-0 cxd4 7.Qxd4 e5 8.Qd3 h6 9.c4 is another, very different direction, and; 6.Nc3 is a third way, aiming for a more traditional Open Sicilian position.]
6...dxc5 7.Nc3 e6 8.Bf4 Ne7 9.Ne5 Ng6 [9...Bb5 10.Qh5 g6 11.Qf3 Nc6 12.Nxc6 Bxc6 13.Be5 Rg8 14.Rd1 Qg5 15.Bf6 Qh5 16.g4 Qh6 17.g5 Qh4 18.Qg3 Qxg3 19.hxg3 b5 20.f3 Be7 21.Rxh7 Ra7 22.Kf2 Rd7 23.Rxd7 Bxd7 24.Nd1 Bxf6 25.gxf6 e5 26.g4 Be6 27.a3 g5 28.Ke3 a5 29.Nf2 c4 30.Nh3 Rg6 31.Rh8+ Kd7 32.Ra8 a4 33.Rh8 Kd6 34.Rh5 Rxf6 35.Nxg5 Bd7 36.Nh3 Rg6 37.Ng1 Rg8 38.Ne2 Rb8 39.Kd2 b4 40.axb4 Rxb4 41.Kc3 Rb5 42.Ng3 Ra5 43.Nf5+ Kc7 44.Kb4 Rb5+ 45.Kc3 Ra5 46.Kxc4 a3 47.bxa3 Rxa3 48.c3 Ra2 49.Ne3 Rf2 50.Rh3 Kd6 51.Kb4 f6 52.Nd5 Be6 53.c4 Rb2+ 54.Kc3 Ra2 55.Nxf6 Kc5 56.Nd5 Bxg4 57.Rh7 Ra3+ 58.Kb2 Rxf3 59.Rg7 Be6 60.Re7 Bg8 61.Rxe5 Kxc4 62.Rf5 Rxf5 63.Ne3+ Kd4 64.Nxf5+ Kxe4 1/2-1/2 Adams,M (2729)-Bu Xiangzhi (2708)/Yerevan 2008]
10.Qh5! Bc6 After 31 minutes! [10...Nxe5 eliminates the possibility of 11.Nxg6, but gives Black a tempo down version of the game.; 10...Qh4 11.Qxh4 Nxh4 12.0-0-0+/= ]
11.Bg3 [11.Nxc6 Nxf4 12.Nxd8 Nxh5 13.Nxb7 Rb8 14.Na5 Rxb2= ; 11.Nxg6 fxg6 12.Qg4 looks like the principled approach. 12...Qf6 13.0-0-0+/= ]
11...Nxe5 12.Bxe5 c4 13.0-0 Qa5 14.Qg5 h6 [14...f6?! 15.Bxf6 ; 14...Bd6? 15.Nd5!+- exd5 (15...Bxe5 16.Qe7# ) 16.Bxd6 f6 17.Qxg7+- ]
15.Qg3 f6 16.Qg6+ Ke7= It may look ugly, but if White can't take advantage it doesn't matter. If Black can weather White's initiative, he can hope to take over with his bishops.
17.Bf4 Be8 18.Qg3 Kf7 19.Rad1 Bc6= 20.Rd2 [Prophylactically-minded moves like 20.Bd6 ; and 20.a3 may be just what the doctor ordered.]
20...e5 21.Be3 Bb4 22.f4 Otherwise White is out a pawn for nothing.
22...Rhe8 23.f5 Bc5 [23...Bxc3?! 24.Qg6+ Kf8 25.bxc3 is unclear, but (25.Bxh6 actually favors Black after 25...Qb6+ 26.Rdf2 Qc7 27.bxc3 Qf7=/+ ) ]
24.Rfd1 Rad8 25.Rxd8 Bxe3+ 26.Qxe3 Rxd8 27.Rxd8 Qxd8 The position is nearly equal, but Black, to adapt an Orwellianism, is more equal than his opponent. White's e-pawn is slightly weak, while Black has the plan of advancing his queenside pawns; I don't see any corresponding counterplay from White's side of the board.
28.Kf2 Qd6 29.a3 a5 30.Kf3 [30.Ke2 ]
30...Kg8 A good prophylactic move, preparing ...b5 by eliminating Qa7+ possibilities, and squirreling the king to general safety.
31.g3?! [31.Ke2! b5 32.Qb6 and now the king on e2 stops immediate Black penetration while also getting out of the way of ...Bxe4+ tricks.]
31...b5=/+ 32.Ke2 b4 33.axb4 axb4 34.Nd1 Ba4 35.b3?-/+ [35.Qd2 is better. 35...Qd4 36.Qxd4 exd4 37.Kd2 is better for Black, but not winning. 37...Kf8 38.b3! cxb3 39.cxb3 Bxb3 40.Nb2 Ke7 41.Kd3 Kd6 42.Kxd4 holds.]
35...cxb3 36.cxb3 Qa6+ 37.Kd2 Bb5 38.Qc5 Qa2+ 39.Qc2? [39.Ke1?? Qe2# ; 39.Kc1 Be2-/+ ]
39...Qa7!-+ 40.Qc8+? Kh7 41.Kc1 Qa1+ 42.Kc2 Qd4 White's king is in some trouble and almost all his pawns are likely goners. 0-1
