Slav Defense · D10

Main line, through 2... c6

1. d4 d5 2. c4 c6

...c6 defends d5 WITHOUT locking in the c8-bishop - the point of the whole system; Black develops it to f5 or g4 before playing ...e6.

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.
