Black keeps the extra pawn; White plays for time, open lines, and initiative - the classic gambit trade. Black has doubled pawns on the b-file.

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. b4 Challenges the pawn on c5 - the central tension has to resolve. The pawn is genuinely on offer - this is the Wing Gambit: development and initiative over material.
• 2... cxb4 Takes the pawn on b4.
