An early pawn trade leaves the c-file as White's avenue and the d-file as Black's - both sides get real winning chances down their own file. Black's kingside bishop takes the long diagonal. Kings castle on opposite wings - expect pawn storms racing at both kings.

The first 4 moves, explained

• 1. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
• 1... Nf6 Develops the knight to f6, eyeing d5 and e4.
• 2. c4 Fights for d5 from the flank - contesting the centre without committing a centre pawn.
• 2... g6 Prepares the fianchetto: the bishop will take the long diagonal via g7. Theory calls this the West Indian Defense.
