Support d5 and free the bishop
The Slav begins with 1.d4 d5 2.c4 c6. Like …e6, the move supports d5. Unlike …e6, it leaves the c8-bishop’s diagonal open. Black may develop that bishop to f5 or g4 before playing …e6.
The trade-off is that the c6-pawn occupies the natural square of Black’s b8-knight. That knight may develop to d7. White should not expect the same pressure points as in the Queen’s Gambit Declined; the position has its own logic.
Example board: compare the support pawn
Black’s c-pawn supports d5 while the light-squared bishop remains free.
Develop and keep your options
Nf3 and Nc3 are natural, but the order can matter. Nf3 avoids blocking the c-pawn’s former square and controls e5. Nc3 increases pressure on d5 and supports e4. White can play e3 for a solid setup, but should notice whether Black has already developed …Bf5.
Do not try to refute the Slav in a few moves. White normally earns small advantages through space, pressure and more active piece placement. Castle, connect the rooks and identify whether your play belongs in the centre or on the queenside.
Example board: Black develops the bishop
Black has solved the light-squared bishop. White should challenge the centre rather than attack the bishop without preparation.
When Black captures and tries to hold c4
Black may play …dxc4 and then …b5. White often answers with a4 before the queenside pawns become secure. The move a4 attacks b5 and makes it harder for Black to keep the extra pawn.
Combine a4 with e3 and normal development. If you chase pawns while leaving pieces asleep, Black may return the pawn and keep the lead in activity. As in the Accepted, attack the support behind c4.
Example board: stop …b5 with a4
White has already played a4, making it harder for Black to build a stable pawn chain.
Challenge the centre at the right moment
White’s central options include e3 followed by Bd3 and O-O, or a prepared e4. Exchanging cxd5 can simplify the structure, but it may also release Black’s pieces. Ask which side benefits from the open lines.
If Black plays …e6 after developing the bishop, the position resembles a solid Slav structure with the bishop already outside the chain. White should use space and pressure rather than waiting for a bishop problem that Black has solved.
Common mistakes
- Treating the Slav like the QGD: the c8-bishop is not trapped by …c6.
- Allowing …dxc4 and …b5 without a response: consider a4 early.
- Attacking …Bf5 with random pawn moves: keep development and king safety first.
- Playing e4 without support: Black can strike the centre quickly.
- Exchanging all the tension: understand what opens before cxd5.
Practice and memory card
- …c6 supports d5 without blocking the c8-bishop.
- Develop Nf3 and Nc3, then choose e3 or a prepared e4.
- Watch for …dxc4 followed by …b5.
- a4 attacks the support of an extra c4-pawn.
- Use space and pressure when Black has already solved the bishop.
Quick questions: What is the difference between …c6 and …e6? Why is a4 useful? What changes after …Bf5?
Reveal answers
…c6 leaves the c8-bishop free. a4 makes …b5 harder and attacks the pawn chain that may support c4. After …Bf5, Black has solved the bishop, so White should develop and seek central or queenside pressure.
