1.d3 {If 1...d6 is sound against any first white move then 1.d3 must be even better. } e5 2.g3 d5 3.Bg2 c6 4.Nf3 Qc7 5.O-O Nf6 6.Nc3 Be7 7.e4 d4 8.Ne2 O-O 9.h3 Bd7 {Perhaps better was 9...c5} 10.Ne1 Ne8 11.g4 {Here 11.f4 was better} f6 12.f4 c5 13.c4!? {It is more standard in this type of position to play c3 undermining Black's centre. However, the idea here is to block the Queen side and play on the King side.} Nc6 14.Nf3 a5 15.a4? {The is the logical follow-up to 13.c4 as it blocks the Queen side but it is a positional mistake that gives b4 to Black. } (15.fxe5 fxe5 16.Ng3) 15...Nb4 16.Ne1 Nd6 (16...Qb6 17.Nc2 Nxc2 18.Qxc2 Nc7 {Followed by Na6 and Nb4 and Black is doing fine.}) 17.Nc2 Nc6 18.b3 Nf7 19.Bd2? {Better was 19.f5} exf4 {Clearing e5 for a knight but conceeding d5} 20.Nxf4 Bd6 21.Nd5 Qd8 {The best move. 21...Bh2+ followed by 22...Qb8 does not achieve anything good for Black.} 22.Na3 Nce5 23.Bf4 Bc6 24.Nb5! Bxb5 25.axb5 b6 26.Kh1? {26. Ra2 immediately is better.} Ng6 27.Bc1 Nfe5 28.Ra2 Ne7 29.Nf4! Qd7 30.Raf2 N7g6 31.Nd5 Rab8 32.Bf3!? {The idea is to transfer the Bishop to e2 and free the Queen from the defence of the d3 pawn.} Nh4 33.Be2 Nf7? {A mistake that loses a pawn.} (33...Neg6 34.Rg1 Ne7 35.Nf4 Bc7 36.Rff1 Nhg6 37.Nh5 Rbe8 {is roughly equal}) 34.Rxf6! Ne5 35.Rxf8+ Bxf8 36.Qe1 Nhg6 37.Rf5 (37.Qf2 Bd6 38.Qf5 Rf8 39.Qxd7 Rxf1+ 40.Kg2! Nxd7 41.Kxf1 Ne7 42.Nxe7+ Bxe7 43.Bf4 {is good for White} Bf6 44.g5 Be5 45.Bd2 {Followed by Bg4}) 37...Bd6 38.Bg5 h6? (38...Qe6 39.Qf2 Nf7 40.Bd2 Rb7 {With the idea of Bb8 and later Qd6 with counterplay}) 39.Bxh6 Ne7 40.Nxe7+ Qxe7 41.Bg5 Qe6 42.Qh4!? Re8 43.Kg2 Rf8 44.Qf2 {Black resigns although there is plenty of play left. White will exchange the rooks and get the Queen to f5, rendering the position very uncomfortable for Black.} {#r}
