This was played last week during a local team cup. Unfortunately we lost very closely despite this win.

2005.11.13 1-0 C88e
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 b5 7.Bb3 d6 8.c3 Na5 Black delays castling unusually long. The downside of the knight move is the weakening of e5, which allows white to attack the center right away without the fear of Bg4. 9.Bc2 c5 10.d4 Nc6 11.d5 Nb8 12.a4 bxa4? A critical mistake which black will regret for the entire length of the game. Now the a-pawn becomes very weak and c6 an ideal outpost for my knight. Necessary was Bb7 or b4.
13.Bxa4+ Bd7 14.Nbd2 O-O 15.Bxd7 Nbxd7 16.Nc4 Nb6 17.Na5 Qc7 18.Nc6 There it is. White has a big advantage already. 18…Rfe8 19.Bg5 Kf8 20.Bxf6 Bxf6 21.Qe2 Qb7 ( 21…a5 would have been an interesting way to keep the pawn. It is indirectly covered by the Queen, since Nxd5 is threatened.) 22.Nd2 Ra2 would have been more accurate. 22…Bg5 23.Nb3 Nd7 Nxd5? fails to Nba5 24.Nba5 Qc7 25.Ra2 Nb8 26.Rea1 Qb6 27.Nc4 Qc7 28.Nxb8 Qxb8 29.Rxa6 It was just a matter of time. 29…Rxa6 30.Rxa6 White has a winning advantage, despite the rather weak extra pawn. The next three moves already decide the game. 30…Be7 Better Rd8 31.Nb6 Rd8 32.Qb5 Qb7 33.Qc6! A killer move, since the black queen has no place to go. If it takes the white queen, the pawn will be unstoppable. Black is forced to give up more material and the game is practically over. 33…Qxa6 34.Nd7+ Rxd7 35.Qxa6 Rd8 36.Qb7 Ke8 37.b4 cxb4 38.cxb4 Rd7 39.Qb8+ Bd8 40.b5 Rc7 41.g3 Kd7 42.b6 Rc1+ 43.Kg2 Rb1 44.b7 Rc1 45.Qxd8+ 1-0
