This aims to push back Black further, and also to discourage kingside castling.}   Nc5 13.Qc2 Bf5 14.Qd1 e5   {?! This looks like a dubious idea, as it expose the Black position.}   15.dxe6 Bxe6 16.h5 Qd7 17.h6 Bf8 18.Nxe6   {18.b4! was more incisive, e.g. 18...Nce4 19.Nxe4 Nxe4 20.Nxe6 Qxe6 21.Bf3 Qxc4? 22.Qd4!}   Nxe6 19.Nd5 Be7 20.Bg4 Nxg4 21.Qxg4 O-O-O   {? 21...Bd8 followed by ...0-0 was better, when Black was still in the game.}   22.Bxa7   {White wins a pawn and gains a strong attack.}   Rhe8   {?! This leads to the Black pieces becoming uncomfortably bunched. 22...Rhf8 is better.}   23.O-O Nc5 24.Qg3 Ne4 25.Qa3 Qc6 26.b4   {This is good, but even better was 26.Rfe1! which exploits the position of the Black pieces on the e-file.}   Bf8   {26...Qxc4 27.Nb6+! cxb6 28.Rac1 wins the queen; 26...Qa6 was a better try, but 27.Qh3+ Rd7 28.Qe6 Ng5 29.Qe3 leaves Black all tied up; 26...b5 27.Qd3 Nf6 28.Rac1 gives a strong attack.}   27.b5 Qd7   {27...Qxc4 28.Qh3+ Rd7 29.Nb6+! cxb6 30.Rac1 wins the queen.}   28.Bb6 {!} Qf5   {28...cxb6 29.Qa8#}   29.Bxc7   {Black resigned, as he loses on the spot if he avoids the loss of the exchange: 29...Rd7 30.Qa8#.}   1-0
