Semi-Slav Defense Accepted · D44
Main line
1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. Bg5 dxc4
An early pawn trade leaves the c-file as White's avenue and the d-file as Black's - both sides get real winning chances down their own file. Black comes out ahead on material - White needs concrete play to justify it.
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. c4 Challenges the pawn on d5 - the central tension has to resolve. The pawn is genuinely on offer - this is the Queen's Gambit: development and initiative over material.
- 2... c6 Fights for d5 from the flank - contesting the centre without committing a centre pawn. Theory calls this the Slav Defense.
