Queen's Pawn Game: what should Black play?

In the Queen's Pawn Game after an early bishop development, Black faces an immediate choice regarding how to contest the center and exploit White's early movement of the dark-squared bishop. While d5 is by far the most frequent continuation across ratings, the engine's top evaluation belongs to Qb6 (+0.14), which immediately pressures the weakened b2 square. By prioritizing rapid queen activity or solid central claims, Black can steer the game into several distinct structures.

The Aggressive Engine Choice: Qb6

The move Qb6 appears in 1.3% of games (115K recorded) and delivers the lowest engine evaluation for White at +0.14, with White scoring 47.5% from this position. Because f4 vacated the queenside, the pawn on b2 becomes an immediate target. In the engine main line Qb6 Nf3 Nf6 Nbd2 Nh5 Be3, Black shifts focus toward hunting down the bishop pair while keeping White's pieces tied to modest defensive squares.

The Classical Main Line: d5

By a wide margin, d5 is the standard human continuation, played in 83.7% of games (7.20M recorded) with White scoring 52.2% and an engine evaluation of +0.37. This move locks down the center and stakes a firm spatial claim, typical of Slav-like setups against the London System. The sample line d5 e3 Bf5 c4 Qb6 Qc1 illustrates a balanced setup where Black rapidly activates the light-squared bishop and queen to contest the queenside.

Flexible Alternatives: d6, Nf6, and g6

Black can also opt for flexible setups that delay central pawn commitment. The move d6 represents the second most common choice, seen in 10.4% of games (896K recorded, +0.55 evaluation), often aiming for King's Indian or Pirc structures after d6 Nd2 Nf6 e4 g6 Ngf3. Alternatively, Nf6 (3.0% of games, +0.23 eval) and g6 (1.5% of games, +0.41 eval) provide resilient setups that maintain multiple paths for piece development.
