Blackmar-Diemer Gambit Accepted · D00

Kaulich Defense

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 c5

Black keeps the extra pawn; White plays for time, open lines, and initiative - the classic gambit trade.

The first 4 moves, explained

• 1. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
• 1... d5 Stakes a claim in the centre, controlling e4, and frees the bishop and queen.
• 2. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen. The pawn is genuinely on offer - this is the Blackmar-Diemer Gambit: development and initiative over material.
• 2... dxe4 Takes the pawn on e4, toward the centre and opens the d-file for the queen.
