Modern Defense: what should White play?

In the Modern Defense after Black fianchettoes the dark-squared bishop, White enjoys broad freedom to stake out central territory. The engine's preferred continuation is c4 (evaluated at +0.53), which transitions into a broad pawn center and claims extensive space. White can also opt for rapid piece development or direct central control with several other reliable setups.

Strategic choices and central setups

White's most popular response in recorded games is Nf3, played in 54.3% of games (4.96M recorded) with an evaluation of +0.44. Developing the other knight via Nc3 is chosen in 30.8% of games (2.82M recorded) and holds an evaluation of +0.47. Players who prefer a solid pawn structure often turn to c3, which accounts for 14.9% of games (1.36M recorded). More aggressive spatial setups include f4 (+0.46) to build a three-pawn front, while h3 (+0.39) provides a quiet prophylactic alternative.

Illustrative engine continuations

The top-ranked engine choice, c4, often leads toward King's Indian or Benoni structures, as seen in the sample continuation c4 d6 Nc3 Nf6 h3 e5. If White instead chooses the direct development of Nc3, play can immediately sharpen in the center via Nc3 d5 Nxd5 c6 Ne3 Qxd4. In the classical path starting with Nf3, the engine illustrates harmonious development through Nf3 d6 Nc3 Nf6 Bf4 O-O. When White seeks extra kingside space, f4 may be met by flank counters such as f4 c5 d5 d6 a4 a6.
