1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d6 5.Nc3 g6 6.Be3 Bg7 7.Be2 Nf6 This position is deemed to be equal - only 47% White in 3495 games.
8.f3 With the Bishop on e2 White does not normally play this move, he plays the Classical system for White involving f4 and castling.

10...Rc8 is only 35% White in 327 games.]
8...O-O 9.Qd2 White has switched to a Yugoslav attack set up, though his Bishop is normally on c4 instead of e2.
9...a6 I might have got the move order slightly wrong as I am playing these moves from memory, and I was watching 4 other games at the same time. Black may have played Bd7 first.

13.Nb3 Qc7 14.h5 b4 ?! This does not work out too well, but it's difficult for Black as White's attack is well under way , Black's is well behind. Rac8 may be best.
[14...Rac8 15.Bh6 Bxh6 16.Qxh6 g5 Giving up a pawn to close the h file may be the best bet.
17.Qxg5+ Kh8 White is better, but his attack has slowed.]

[24.Qg7 Edgar decided on analysing the game that this was the strongest move. White has a winning attack.]
24...Kd8 25.Qg7 Re8 26.g5 ?! threatening Bh5, but not the best.
[26.Rh8 ! is a killer. The threat is 27.Rxe8ch Bxe8 28.Ne6ch
26...Kc8
(26...Qc8 27.Rxe8+ Bxe8 28.Ne6+ Kd7 29.Qd4 wins the Knight)
