Sicilian Defense · B40

Kan Variation, Wing Attack, Fianchetto Variation

1. e4 c5 2. Nf3 e6 3. Nc3 a6 4. g3 b5 5. d4 cxd4 6. Nxd4

An early pawn trade leaves the c-file as Black's avenue and the d-file as White's - both sides get real winning chances down their own file. ...a6 and ...e6 first: Black stays flexible, keeps the pieces at home until White commits, and picks the right setup afterwards.

The first 4 moves, explained

• 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
• 1... c5 Fights for d4 from the flank - contesting the centre without committing a centre pawn. Theory calls this the Sicilian Defense.
• 2. Nf3 Develops the knight to f3, eyeing d4 and e5.
• 2... e6 Supports the centre, adding control of d5. Theory calls this the French Variation.
