This is an interesting game where both sides miss material gaining moves. White gets his pieces into bad lineups, giving Black chances. But in the end, as in the opening, black ignores the defense of the vital f7 pawn, and is soon checkmated. 1.d4 d5 2.c4 c6 3.Nf3 dxc4 4.e4 Bg4 5.Bxc4 Nf6 6.Nc3

6.Bxf7+ exposes the black king. Then Kxf7 7.Ne5+ Ke8 (or g8) 8.Nxg4 regains the piece. Black then has ...Nxe4 with even material but a clear white advantage. g6 7.b3 Bg7 8.Bb2 0-0 9.d5? This is a premature pawn push, opening the long diagonal a1-h8. Black could answer 9...Nxe4, creating a pin on the c3 knight and winning a center pawn. 9...Na6 10.e5

10.dxc6 undermining b7 support of the Knight on a6 is better. White's central pawns are exposed to attack, so he should look for a good way to exchange them. 10...Ne8 11.0-0 Nec7 12.Ba3 White doesn't have time for this. Now Black can pick up a key central pawn with Bxe5. 12...c5 13.d6 exd6 14.exd6 Ne8 Instead of retreating, Black could exchange knights. 14...Bxc3 15.Rc1 Bb4 16.Bxb4 Nxb4 17.dxc7 Qxc7 is better for black. 15.Rc1 Nxd6 16.Bxa6 bxa6 17.Bxc5 Be5 18.h3 [18.Nxe5 Bxd1 19.Rfxd1 Rc8 20.Bxd6 would create a dynamic position with 3 pieces for the queen. Miscalculating this variation risks losing the game though. 18...Bxf3 19.Qxf3 Rc8 20.b4 a5

Playing on the side of the board with the center open gets Black into trouble. White attacks in the center! 21.Qd5 Bg7 Re8 is necessary. 21...Re8 22.f4 (trying to win a piece) Bxc3 23.Rxc3 Ne4 is good for Black. In this variation, White should prevent ...Bxc3 with 22.Na4. 22.Bxd6 White captures a piece, but Black could just take it right back. Simpler was 22.Qxd6. The problem is that White self-pins his bishop. 22...Re8 He could take the knight on c3. This removes the guard for the white queen, thus pinning the bishop on d6, and saving the f8 rook. 23.Rfd1 Qh4? Bxc3 wins the piece back. 24.Bg3 Qxb4 25.Nb5 Rxc1 26.Rxc1 Re1+ 27.Rxe1 Qxe1+ 28.Kh2 h5 29.f3 Qf1 29...Qe7 helps defend the key f7 pawn. After this lapse, White wins the game very quickly. 30.Nd6 Bh6 31.Qxf7+ White goes for checkmate. 31...Kh8 32.Be5+ Bg7 33.Qxg7#
