2006 Class Championship R1

Prong,C (1786) - Cottrell-Finegold,K (1660)
2006 Michigan Class Championship, 1.14.2006
Sicilian Defense: Najdorf Variation [B98]

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Be7 8.Qf3 0-0
This was the second time Kelly had played this against me in a month, and it is a move that is rarely played. Qc7 is the book line, but 0-0 is found over 100 times in the Chessbase database.
9.0-0-0
Nfd7 While Nbd7 is more common in miost Sicilian systems, it seems that Nfd7 seems to simply trade off some pieces.
10.Bxe7 Qxe7 11.g4 Nc6 12.Nb3
At the MCA Action Championships I played Nxc6 to give me an extra tempo attacking on the kingside.
12...b5 13.e5 d5 14.Bd3 Bb7 15.Qh3 g6 16.Rhg1
In a similar position against Kelly in December I played g5, preventing f6, and got a strong attack down the h-file.
16...f6 17.exf6 Rxf6 18.Rde1 Nb4 19.f5 Nxd3+ 20.Qxd3 Nc5 21.Qd4 Ne4
Nxb3+ was better since black's e pawns are weak after Nxe4 dxe4. 22.Nxe4 dxe4 23.Nc5 Rd8 24.Qf2
I saw Qe5 Rd5, but missed the follow up Qb8+ Rf8 Qxb7 while at the table.
24...exf5 25.gxf5 Qf7?
The black rooks are on the same diagonal, so after Nxb7 Qxb7 the queen gets out of the way with tempo and gives white time to win a pawn.
26.Nxb7 Qxb7 27.Qh4 Qf7 28.fxg6 hxg6 29.Qxe4 Rdd6 30.b3 Rfe6 31.Qg4 Qf6 32.Kb1 Rxe1+ 33.Rxe1 Kg7 34.Qe4 Rd7 35.h4 Rd6
Rd4 wins back the pawn on h4
36.Rg1
My plan was to play h5 next winning trading off the pawn for its counterpart on g6.
36...Rd4


37.Rxg6+!!
Clearly my best move of the game. This move wins a second pawn, and trades off more material.
37...Kh7 38.Rxf6+ Rxe4 39.Rxa6 Rxh4 40.a3 Kg7 41.Rb6 Rh5 42.Kb2 Kf7 43.Kc3 Ke7 44.Kb4 Rh2 45.Rc6 Rh5 46.Rc5
Winning the last remaining black pawn.
46...Rh6 47.Kxb5 Kd7 48.a4 Rh8 49.a5 Ra8 50.b4 Kd6 51.c4 Rb8+ 52.Ka4 Ra8 53.Rh5 Rc8 54.Rh6+ Kc7 55.b5 Kb8 56.Kb4 Rc7 57.a6 Rc8 58.Rh7 Ka8 59.b6 Rb8 60.Ra7# 1-0
