1.e4 c5
The Sicilian Defense

2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6
A very flexible approach by black. 6.Bg5 is the Rauser. 6.Bc4 is the Sozin

6.Bg5
The more positional approach, featuuring quick and effective development and the choice of f2-f3 or f2-f4

6...Bd7
...e7-e6 is more common. Black prefers quick queenside mobilization and avois the weakening of the d6-pawn.

7.Qd2
Avoiding Bxf6 which doubles the black f-pawns but cedes the two bishops and gives black good dark-square mobility later in the game.

7...Rc8
Black prefers quick counterplay on the queenside to safeguarding his king.

8.0-0-0 Nxd4 9.Qxd4 Qa5 10.f4
