Zukertort Opening: Nimzo-Larsen Variation: what to play after Nf3?

In the Zukertort Opening: Nimzo-Larsen Variation (ECO A05), Black faces a hypermodern setup where White prepares to fianchetto on the queenside. Engine analysis narrowly favors d6 (evaluated at -0.05), a flexible continuation that controls key central squares like e5 while keeping piece development open. With 855,366 recorded games reaching this position, Black enjoys near-complete equality across several viable setups.

Strategic Goals of d6

Opting for d6 allows Black to counter White's slow, flank development by maintaining maximum versatility. Rather than committing the central pawns immediately to fixed positions, this pawn push controls e5 and blunts White's upcoming queenside fianchetto. An illustrative engine continuation runs d6 d4 Bf5 e3 e6 Bd3, where Black readily develops the light-squared bishop outside the pawn chain before settling into an active structure.

Central Counterstrikes: d5 and c5

Black can also stake an immediate claim in the center with classical thrusts. The central strike d5 (evaluated at -0.04) directly challenges the center; an illustrative continuation shows d5 Bb2 Bf5 Nh4 Bd7 g3, demonstrating active bishop maneuverability. Alternatively, the popular c5 evaluates at a dead-level +0.00 and can lead into Sicilian-like or English-style setups, illustrated by the continuation c5 Bb2 Nc6 e3 g6 d4.

Alternative Setups: c6 and e6

Both c6 (+0.05) and e6 (+0.05) offer sound, solid options that blunt White's pressure along the long diagonal. The move c6 often supports a later central advance, illustrated by c6 e3 d6 d4 Bf5 Nh4. Meanwhile, e6 fosters quick kingside development, with the sample line e6 e3 c5 d4 Nc6 Be2 resulting in a harmonious central layout.
