White is up material out of the opening - Black is banking on activity to show for it. White's kingside bishop takes the long diagonal and Black's kingside bishop takes the long diagonal.

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... c5 Challenges the pawn on d4 - the central tension has to resolve. Theory calls this the Benoni Defense.
