Scandinavian Defense: Modern Variation: what to play after Nf6?

In the Scandinavian Defense: Modern Variation (ECO B01), White's most critical choice against the knight's challenge to the d5 pawn is d4, securing central space while preparing natural development. Evaluated at +0.67 by chess engines, this advance is the most popular continuation in the database, appearing in 19.0% of recorded games (638K games). White allows Black to recapture on d5 while prioritizing smooth piece coordination and rapid central control.

The Strategic Value of d4

Playing d4 stakes an immediate claim over the center and frees the dark-squared bishop. In the engine main line d4 Qxd5 Nc3 Qd6 Nf3 c6, White develops with tempo against the centralized black queen via the queenside knight, quickly establishing harmonious piece activity while Black must spend moves reorganizing.

Flexible Development with Nf3

The closest rival is Nf3, selected in 13.1% of games (440K recorded) with an evaluation of +0.66. It frequently transposes into identical central setups as shown in the continuation Nf3 Qxd5 Nc3 Qd6 d4 c6. Developing the kingside knight first avoids committing the central pawns immediately while denying Black easy activity.

White also utilizes direct piece intervention. The check Bb5+ evaluates at +0.44 and accounts for 3.4% of games (114K recorded), leading into Bb5+ Nbd7 d4 Nxd5 Nf3 a6.
