Clam Variation, King's Gambit Reversed

1. e4 e5 2. d3 f5

In the centre, White holds e4 while Black holds e5.

The first 4 moves, explained

• 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
• 1... e5 Stakes a claim in the centre, controlling d4, and frees the bishop and queen.
• 2. d3 Supports the centre, adding control of e4. Theory calls this the Leonardis Variation.
• 2... f5 Challenges the pawn on e4 - the central tension has to resolve. The pawn is genuinely on offer - this is the King's Gambit Reversed: development and initiative over material.
