Notes by Peter Coleman

B75. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be3 Bg7 7.f3 Nc6 8.Qd2 I prefer this to 8.Bc4. I prefer to save tempi for my pawn storm and leave less targets for my opponent's. Bd7 9.O-O-O Rc8 An old idea of Mestel's, which has become popular again through the play of Tiviakov. Black delays castling and first tries to create counterplay on the queenside. 10.g4 Alternatives are:

[10.Nxc6?! Rogozenko bxc6 11.g4 Qa5 12.Bc4 O-O 13.h4 Be6 Korneev-Hoffman, Ubeda, 1997]

[14...Nb4 15.Nb3]

15.Nxf5!? I had determined to sacrifice a pawn when playing 14.Kb1, but this could also be achieved with

[15.Nxc6!? bxc6! 16.Nd5 Qd8 17.Nf4 Rb8 18.b3 fxe4 19.Nxh5 Bg4 20.Be2 Bxh5 21.Bxh5]

15...Bxf5 I was also prepared for

[15...Bxc3 16.Qxc3 Qxc3 17.bxc3 Bxf5 18.exf5 Ne5 19.h4 Rxc3 20.Bd4 Rc7 21.Be2 Rfc8 The two Bishops give White a solid advantage.]

16.exf5 Qxf5 The pawn must be accepted, e.g.

[16...Nb4 17.f6 exf6 18.gxf6 Nxf6 19.a3 Ne4 20.Nxe4 Rxc2 21.Qxb4]

17.Bd3 For his pawn White has the two Bishops, the initiative and more active pieces. Is it enough? I'm not sure, but felt it was the sort of position that carbon and silicon based brains alike might underestimate. Qa5 Here I had a difficult choice to make

[17...Qe6 18.Nd5 Qe5 19.c3 e6 20.Bxh7+ Kxh7 21.Qc2+ Qf5 22.Qxf5+]

18.Nd5 but the attacking

[18.g6 was also worthy of playing, e.g. fxg6 19.Qg2 Ne5 20.Nd5 Rf7 21.Bxg6 Nxg6 22.Qxg6]

18...Qxd2 19.Rxd2 e6

[19...Be5!?]

20.Nf4 h4 21.g6! breaking Black's pawns up and making them targets for the active White pieces.

[21.Bxh7+ Kxh7 22.Rxd6 Rfd8

(22...e5)

23.Rhd1 Rxd6 24.Rxd6 Rd8 25.Rxd8 Nxd8 26.Bxa7 e5]

21...fxg6 other moves are worse, e.g.

[21...Nf6 22.Rg1 Bh6 23.Rf2 Ne5 24.h3 Nxd3 25.cxd3 Nd7 26.gxf7+ Kxf7 27.Nxe6+ Kxe6 28.Rg6+ Kd5 29.Rxh6 Rxf2 30.Bxf2 a6 31.Rxh4]

22.Nxg6 Rf3

[22...Rf7 23.Nxh4 Nb4 24.Rg1 Nxd3 25.Rxd3 Rc4 26.Ng6]

23.Re1 The weak pawns on d6 and e6 now come under pressure. Nf8 24.Nxh4 Rh3 No better is

[24...Rf6 25.Rg2 Rc7 26.Reg1 d5 27.Bg5 Rff7 28.Be2 Kh7 29.h3 Rfd7 30.Be3 Rf7 31.Bh5]

25.Bg5

[25.Nf5 exf5 26.Bxf5 Rxe3 27.Rxe3 Rd8 is not so strong as the game]

25...Ne5

[25...Nh7 26.Bxh7+ Kxh7 27.Rxe6]

26.Bf1! Instituting a forced sequence that will give rise to an advantageous endgame. Rxh4 27.Bxh4 Nf3 28.Rxd6 Nxh4 29.Bh3 the pawn on e6 must fall Nf3

[29...Rc4 30.Bxe6+ Nxe6 31.Rdxe6 Rb4 32.b3]

30.Bxe6+ Nxe6 31.Rexe6 White has only a small material advantage but the pawns on b7 and a7 are vulnerable because the K is "offside" on g8. Kf7

[31...Nxh2 32.Re7 Rf8 33.c3 Rf7 34.Rxf7 Kxf7 35.Rd7+]

32.Re4 My plan here was to push the h-pawn and at the appropriate time "sacrifice" it in order to win the b-pawn. It seems clear that if White can get a passed pawn on the Q-side it is all over. Ne5

[32...Rc7 33.c4 Ne5 34.b3 Rc6 35.Rf4+ Ke7 36.Rxc6 Nxc6 37.h4]

[32...Nxh2? 33.Rd7+]

33.h4 Ke7 34.Rg6 Bf6 35.Rh6 Rg8 36.a4 Played over the alternatives to prevent Black playing b5, in keeping with my plan to capture the b-pawn. Rg7 37.Rf4 Possibly even better is

[37.h5 Ke6 38.Rf4 Ng4 39.Rh8 Be5 40.Rf3]

37...Rg1+?! This check achieves nothing and makes White's task a bit easier.

[37...Ng4 38.Rh8 Ne5 39.Ka2 Nf7 40.Rc8 Be5 41.Rb4]

38.Ka2 Bg7 39.Rh7 Setting up the next tactical shot. Nd7

[39...Ke6? 40.h5 Nc6 41.h6]

40.h5 Nf8

[40...Nf6 41.Rxf6 is even better for White.]

41.Rxf8 Forced, but strong - and played for! Kxf8 42.h6 Bxh6? or

[42...Bf6 43.Rxb7 a5 44.Ra7 Rg5 45.h7 The three pawns are superior to the Bishop and the relative worth if the Kings is an even greater difference.]

[42...Bd4! 43.Rd7 Rg4 44.h7 Bg7 45.Kb3 Rh4 46.Rxb7 winning, but there's still a fair bit of work to be done]

43.Rxh6 White is o nly a pawn up, and the pawns are all on the same side - but Black's King will not reach them! Fritz prefers this to the other endings, but Fritz is wrong! Rg7 44.Re6! The Black King is now cut off from the pawns. The Rook is headed for e3 where it will protect the third rank - allowing White to advance on the Q-side. Rc7 Black plays mechanically and allows White to achieve his optimum set-up with minimal difficulty. 45.c3 Kf7 46.Re3 Rd7 47.b4 Rc7 48.Kb3 Rd7 49.c4 Rc7 50.c5 Rd7 51.Kc4 Rc7 52.b5 Kf6 53.a5 Kf7 54.c6!
