Steve Ferrero (USCF 1898) - Vesna Dimitrijevic (USCF 1916), USATE 2/18/2008
1.b3 d5 2.Bb2 c5 3.e3 Bf5 4.Nf3 e6 5.Bb5+ Nc6 6.O-O Nf6 7.Ne5 Rc8 8.d3 Bd6 9.Nd2 O-O 10.Bxc6 bxc6 11.Ndf3 Qc7 12.h3 h6 13.Rc1 a5 14.a4 Rb8
15.Bc3 Ra8 16.Kh1 Ne8 17.d4
This move is strategically incorrect for two reasons. First, it creates more light-squared weaknesses for White, who is already minus his king bishop. Second, it enables Black to exchange her doubled c-pawns.
17...cxd4 18.exd4 c5 19.dxc5 Bxc5 20.Bb2 Nf6 21.Nd3 Bb6 22.Nd4 Bg6 23.Nb5 Qd8 24.Qf3 Ne4 25.Qf4 Qg5 26.Qxg5 hxg5
Instead, Black should play 26...Nxg5 with an equal game.

A quicker way to win is 78.Ra8.
