Slav Defense: Three Knights Variation: what to play after Nbd7?

In the Slav Defense: Three Knights Variation, recorded in over 240,000 games, White faces a decision regarding how to handle the central tension. The primary engine recommendation is cxd5, resolving the pawn structure and securing a moderate positional edge evaluated at +0.61. This central exchange clarifies the position before Black can comfortably untangle the kingside pieces.

Resolving the Center with cxd5

The pawn capture cxd5 represents White's highest-evaluated try among the top options. Rather than allowing Black to capture on c4 or establish a solid defensive fortress, White opens the c-file and defines the central pawn configuration. According to the top engine continuation, play can proceed with cxd5 cxd5 Bf4 e6 e3 Nh5, where White develops the dark-squared bishop smoothly before reinforcing the center with e3.

Alternative Continuations

White has several quiet developing alternatives that maintain tension without releasing the central pawns immediately. The active bishop sortie Bf4 posts an evaluation of +0.15, leading into sharp territory after Bf4 dxc4 e4 b5 a4 b4. Similarly, Qc2 shares an evaluation of +0.15, preparing to control the e4-square through lines such as Qc2 e6 cxd5 exd5 Bg5 h6.

Strategic Solidity with e3 and Qb3

For players seeking a classic setup, e3 provides an evaluation of +0.14 and shores up the d4 pawn, intending lines like e3 e6 Qc2 Bd6 Bd3 e5. Finally, the queen thrust Qb3 scores +0.11, aiming to pressure the queenside directly as shown in Qb3 e6 Bf4 a5 cxd5 exd5. While these sidelines remain completely playable, cxd5 remains the most ambitious attempt to claim an advantage.
