96MB, Fritz7.ctg, C86838-D 1.e4 c5 2.Nc3 d6 3.g3 Nf6 4.Bg2 e6 looks like he's going for the non-fianchetto response where Black plays normal Sicilian-type moves.

5.d3 Be7 6.Be3 Nbd7 7.f4 a6 8.h3
to prevent Ng4 after my future Nf3 or Ne7

8...Rb8 9.Nf3 Qc7 10.0-0 0-0 11.g4
Q-side counterplay is minimal, so proceed with developing the attack.

11...b5 12.Qe1 Nb6 13.g5 Ne8 14.Ne2 d5 15.Ng3 Nd6 16.Nh2 d4 17.Bd2 Bb7 18.Ng4 c4 19.Nh5 cxd3 20.cxd3 Qc2
Now I really want to get my Q into the fray at either g3 or h4, but can I abandon my B? It's not participating in the attack anyway. But I can't find a definitive, concrete sequence of moves to end the game, so I decide not to let it go. But is there a way I can get it into the attack?

21.Bb4!
The f6 square is crucial in my attack. Maybe I can deflect his B off of it. [21.Qg3 Qxd2 22.Ngf6+ Bxf6 23.Nxf6+ Kh8 24.Qh4 gxf6 doesn't work.; 21.Qh4 Qxd2 22.Nhf6+ Bxf6 23.Nxf6+ gxf6 24.gxf6 Kh8 doesn't work either.]

21...Qxd3?
he misses the threat!

22.Bxd6! Bxd6 23.Nhf6+! Kh8
[23...gxf6 24.Nxf6+ Kg7 (24...Kh8 25.Qh4 ) 25.Qh4 Rh8 26.Qh6# ]

24.Qh4 h6
[24...gxf6 25.Nxf6 ]

25.Nxh6! gxf6 26.Ng4+
a very satisfying game, and another notch for the Closed. 1-0
