This opening starts quietly, but the statistics show that it is far from dead. Across 1,312,261 games at this exact position, White wins 49.2%, draws 4.1%, and Black wins 46.7%.

In a position like this, good development and sensible piece activity matter more than flashy ideas.
What the engine prefers here
The engine’s best move here is c4, with the continuation c4 Nf6 e3 Be7. That is a useful signal for Black: White is often trying to seize space and build a calm, flexible middlegame. Your task is to answer that kind of structure with solid development and careful coordination. In the drill, focus on recognising when White pushes for space and when you should keep your pieces active without weakening your position.

In practical terms, you should be ready for quiet development, queenside expansion, and central grabs.
How Black should think in this structure
Because the position is dead level, your goal is not to prove superiority immediately. Instead, build a sound setup, keep your king safe, and avoid careless loosening of the queenside or centre. White may try to claim space, but that also gives you clear targets for piece activity if you stay disciplined. This is a good opening for players who like flexible positions where understanding matters more than memorised forcing lines.
