Slav Defense: Slav Gambit, Alekhine Attack: what should White play?

In the Slav Defense: Slav Gambit, Alekhine Attack, White faces a decision regarding how to contest Black's early piece development. With over 120,941 games recorded in master databases, White's most critical choices center on advancing in the center with d5 or developing the kingside with Nf3. The central thrust d5 immediately challenges the light-squared bishop and claims space, granting White an engine evaluation of +1.43.

Space Gains with the Central Push

The primary thematic option is d5, which strikes directly at the pawn on c6 while forcing Black's bishop on e6 to resolve its placement. According to modern analytical engines, the main continuation unfolds with d5 cxd5 exd5 Bf5 Nf3 Nf6. This sequence opens central lines, liquidates Black's support on the queenside, and leaves White with active piece play and lasting central control.

Developing Knights and Alternative Approaches

White may also prioritize piece deployment by selecting Nf3, which carries the highest raw evaluation at +1.50. This move readies kingside castling while eyeing the advanced e6 bishop via Nf3 g6 Ng5 Bg7 Nxe6 fxe6, thereby compromising Black's pawn structure. Other viable paths include Nge2 (evaluated at +1.11), which often continues Nge2 b5 Nf4 Bc8 e5 e6, and the prophylactic flank push a4 (+0.96), followed by a4 g6 d5 cxd5 exd5 Bf5. Alternatively, quiet development via Be2 (+0.92) leads to steady setups such as Be2 Nf6 f4 g6 Nf3 Bg7.
