Budapest Gambit Accepted, Main Line, Rubinstein Variation

1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. Bf4

An early pawn trade leaves the d-file as White's avenue and the e-file as Black's - both sides get real winning chances down their own file. White is up material out of the opening - Black is banking on activity to show for it.

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... e5 Stakes a claim in the centre, controlling d4, and frees the bishop and queen. The pawn is genuinely on offer - this is the Budapest Gambit: development and initiative over material.
