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. Black's kingside bishop takes the long diagonal. By fianchettoing before ...d6, Black keeps ...d5 in one move as an equalizing break - but must respect the Maroczy bind (c4) that this move order allows.

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... Nc6 Develops the knight to c6, eyeing d4 and e5. Theory calls this the Old Sicilian.
