Dutch Defense: what to play after c4?

In the Dutch Defense (ECO A84), reached after 1. d4 f5 2. c4, Black's primary choices are Nf6 and e6. While Nf6 is by far the most frequent continuation, played in 79.6% of recorded games (7.86M recorded) with an engine evaluation of +0.49, e6 is the engine's top choice at +0.48, chosen in 17.0% of recorded games (1.68M recorded). Both options develop naturally and contest central control, though e6 offers immediate flexibility regarding the placement of Black's kingside pieces.

Development with e6 versus Nf6

Choosing e6 prepares kingside development via the f8 bishop while blunting potential checks along the h5-e8 diagonal. Across 1.68M recorded games featuring e6, White scores 50.9%. An illustrative continuation is e6 g3 Nf6 Nf3 Be7 Bg2, transposing into classical Dutch structures where White fianchettoes the light-squared bishop. In contrast, the most heavily played move, Nf6, leads to Nf6 g3 e6 Nf3 Be7 Bg2, reaching the same pawn structure while allowing White a slightly lower score of 50.3%.

Less Common Alternatives

Deviations from the two main lines occur infrequently in database practice. Black selects d6 in 2.5% of games (251K recorded), evaluated by the engine at +0.54, leading to illustrative lines such as d6 Nf3 g6 g3 Nf6 Bg2, where White scores 52.3%. The solid setup c6 appears in 0.9% of games (90K recorded, engine eval +0.61, White scoring 53.3%), with c6 Nf3 Nf6 Nc3 g6 Bf4 as a representative continuation. An offbeat trial is Na6 (+0.77), which can be met by Na6 Bf4 Nf6 e3 e6 a3.
