Slav Defense, Exchange Variation

In the Slav Defense, Exchange Variation , Black has defended the central d-pawn with the c-pawn. White captures the d-pawn with the c-pawn, and Black normally recaptures with the pawn that stood on c6. The result is an almost symmetrical central structure: both sides have a pawn on the d-file, on d4 or d5, and very similar pawn chains.

The symmetry removes some of the normal Slav tension, but it does not make the game automatic. White has the first move and can try to use that small lead in development to place pieces actively. Both sides look for differences through piece placement, favorable exchanges, and well-prepared pawn advances. With fewer pawn imbalances, piece activity becomes even more important.

cxd5

cxd5

cxd5 trades White's c-pawn for Black's original d-pawn and removes the tension between c4 and d5.

White chooses to remove the central tension

The c4-pawn can capture on d5, and Black's c6-pawn is ready to recapture.

1. cxd5 trades White's c-pawn for Black's original d-pawn and removes the tension between c4 and d5.
2. The c6-pawn supports d5 and makes it possible to restore the material with ...cxd5.

Comparison with the Queen's Gambit Declined Exchange Variation is especially useful. There, Black's e-pawn recaptures and creates the asymmetric Carlsbad structure. In the Slav, the c-pawn recaptures, so the center is much more symmetrical and the classic minority-attack plans do not arise in the same way.
