Scandinavian Defense: what to play after exd5?

In the Scandinavian Defense (ECO B01), Black's most reliable and practical choice after White captures on d5 is either recapturing immediately with Qxd5 or developing with Nf6. While Qxd5 represents the historical main path, appearing in 70.8% of recorded games (71M recorded), the engine marginally favors Nf6 with an evaluation of +0.64. Opting for Nf6 allows Black to prioritize rapid piece development before resolving the tension surrounding the d5 pawn.

The Modern Alternative with Nf6

Chosen in 20.4% of games (21M recorded), Nf6 delays recapturing the pawn to keep the queen safe from early harassment. By developing the kingside knight toward f6, Black aims to contest the center flexibly. An illustrative engine continuation demonstrates this idea with Nf6 d4 Qxd5 Nc3 Qd6 Nf3, where Black secures the d5 square and repositions the queen to d6 without significant developmental delay.

The Classical Recapture with Qxd5

The most frequent path on the board remains Qxd5, holding an engine evaluation of +0.65. Taking directly on d5 challenges White's central space immediately, though it allows White to develop with tempo. The illustrative engine line runs Qxd5 Nc3 Qd8 d4 Nf6 Nf3, leading to a classical setup where Black retreats the queen all the way to its starting square while maintaining a solid, compact pawn structure.

Minor Continuations and Gambits

Alternative options are far less common at this juncture. Black can attempt the speculative c6, seen in 4.8% of games (4.87M recorded) with an evaluation of +0.67, leading into the line c6 dxc6 Nxc6 Nf3 e5 Nc3. Rare attempts such as e5 and Bf5 each appear in less than 0.5% of games, while engine lines such as g6 (+0.95) and a6 (+0.99) are considered suboptimal compared to the principal variations.
