Nimzowitsch Defense: Scandinavian Variation, Exchange Variation: what should White play?

In the Nimzowitsch Defense: Scandinavian Variation, Exchange Variation, White faces immediate pressure against the d4 pawn and the pinned knight on f3. The top engine choice is c4 (evaluating at +0.30), which immediately contests the center and gains a tempo by kicking the black queen from d5. While Be2 remains the overwhelmingly popular continuation, c4 provides White with active counterplay and central expansion.

The Aggressive Push with c4

Selected in 11.6% of recorded games (258K recorded), c4 forces Black's queen to relocate while establishing central space. White scores 49.1% from this position. An illustrative continuation demonstrating the engine's main line runs c4 Qf5 d5 Bxf3 gxf3 O-O-O, where White accepts a compromised kingside pawn structure in exchange for pushing Black back with central advances.

The Classical Approach: Be2

By far the most common human choice is Be2, played in 46.3% of games (1.03M recorded). Carrying an engine evaluation of +0.22, this solid developing move breaks the pin on the f3 and leads to a 53.9% score for White. A sample continuation follows Be2 O-O-O Be3 e5 c4 Qa5+, transitioning smoothly into dynamic play where both sides mobilize their forces rapidly.

Developing and Solidifying Alternatives

White can also challenge the queen directly with Nc3, chosen in 18.8% of games (420K recorded, evaluation +0.20, scoring 51.7%), leading into Nc3 Qh5 d5 O-O-O Be2 e6.
