Sicilian Sozin 6.Bc4

Throughout the years, I have played many exciting games as White in the Sozin Attack against both 5...a6 and 5...Nc6 in the Sicilian Defense, after the opening moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3.

At the New Jersey Masters Invitational in 1986, international master Mike Valvo who was playing the White side of the Sozin Attack defeated me after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 7.Bb3 b5 8.O-O Be7 9.Be3 O-O 10.f4 Bb7 11.e5 dxe5 12.fxe5 Nd5 13.Nxd5 Bxd5 14.Bxd5 Qxd5 15.Nf5! Nc6 16.Qxd5 exd5 17.Rad1 Rad8 18.Nxe7+ Nxe7 19.Bc5 Rfe8 20.Bd6 with clear advantage for White.

In 1987, at the New Jersey International, Valvo beat Orest Popovych who varied from 10...Bb7 with 10...b4 11.Na4 Bb7 12.e5 dxe5 13.Nxe6 fxe6 14.Bxe6+ Kh8 15.Qxd8! Although White has only two pawns for the sacrificed piece, the passed e-pawn after an eventual fxe5 is difficult to handle.

Ever since these two games, I have adopted Valvo's variation with much success as the following examples will show.

Game #1
