1.e4 c5 2.Nc3 Nc6 3.Bb5 Nd4 4.Bc4 g6 5.Nge2 d6
[5...Bg7 6.Nxd4 cxd4 7.Qf3 Nh6 8.Ne2 is main line]

6.Nxd4 cxd4 7.Qf3!?
This is a tricky move and difficult to play against if black is unfamiliar with the opening

7...e6?
After this move, white gets a big advantage [7...dxc3? doesn't work 8.Bxf7+ Kd7 9.Qh3+ e6 (9...Kc7 10.Qxc3+ ) 10.Qxe6+ Kc7 11.Qc4+ Kb8 12.Bxg8 ; 7...Nh6 8.Ne2 Bg7 9.d3 Bg4 10.Qg3 Bxe2 11.Kxe2= ; 7...Nf6 8.Ne2 Qb6 9.c3 dxc3 10.bxc3= ]

8.Nb5 Bg7
Amazingly, this is my fourth game reaching this position. three of my opponents (all of whom were masters) walked into this position against me at World Open. The move order varied slightly, occuring after 5... Bg7 6. Nxd4 cxd4 7. Qf3 e6? 8. Nb5 d6

9.Qa3 Be5 10.c3 dxc3
[10...d5!? 11.cxd4 Bb8 12.exd5 exd5 13.Bb3+/- Black survives but is down a pawn]

11.d4
black faces many problems and will have to give up material

11...cxb2 12.Bxb2 Bf4 13.g3 a6 14.gxf4 axb5 15.Qxa8 bxc4 16.Qa4+ Bd7 17.Qxc4 Nf6 18.Qd3
[18.d5! A much stronger move that Andrew pointed out to me after the game. 18...exd5 19.Qd4!+- ]

18...Nh5!?
Black is finding ways to exploit white's weaknesses. It is not as easy as it seems to convert for a win.

19.Qd2 Qh4 20.Ba3 Nxf4 21.0-0-0
[21.Bxd6 Ng2+ 22.Kf1 Qh3 Things become unclear (22...Qxe4 23.Qg5 ) ]

21...0-0?!
[21...Bb5!? A move that my coach Dmitry Gurevich pointed out. Black activates his pieces and has good compensation for the exchange 22.Bxd6 ]

22.Bxd6
Now I am able to convert my material advantage without too much difficulty

22...Rc8+ 23.Kb1 Nh3 24.f3 Qh5 25.Rhf1 Bb5 26.Rc1 Rd8 27.Rc5 Qh4 28.Bg3 Qe7 29.Rxb5 Qa3 30.Rb3 Qa6 31.Rc1 Ra8 32.Rbc3 1-0
