Nimzowitsch Defense: Mikenas Variation: what to play after d6?

In the Nimzowitsch Defense: Mikenas Variation (ECO B00), White's most critical and statistically favored response is the central advance d5. This move claims immediate spatial dominance by kicking the knight on c6, earning an engine evaluation of +0.85 and leading White to score 55.5% across 873K recorded games. Classical development with Nf3 or Nc3 also maintains a sound central foundation if White prefers to delay pawn contact.

Seizing Space with d5

The thrust d5 represents White's most popular choice, chosen in 43.6% of the 2.00M games recorded from this position. By driving Black's piece away from the center, White consolidates a space advantage across the board. The engine's illustrative line continues d5 Nb8 Be3 Nf6 Nc3 g6, showing White comfortably developing minor pieces while Black relocates the knight and adopts a kingside fianchetto.

Developing Alternatives: Nf3 and Nc3

Players opting for steady piece development often prefer Nf3, appearing in 33.4% of games with an evaluation of +0.71 and a 54.5% score for White. Against Nf3, the engine illustrates Nf3 Nf6 Nc3 e5 d5 Ne7, demonstrating that White still retains the option to push the central pawn later. Alternatively, Nc3 is selected in 14.4% of games, yielding a 56.0% score and an evaluation of +0.56, meeting central counterplay in Nc3 e5 Nf3 exd4 Nxd4 Nf6.

Flank Options: c4 and h3

White can also reinforce the center through c4, which occurs in 7.7% of games with a +0.59 evaluation and a 53.5% score, transitioning into c4 e5 d5 Nd4 Ne2 Nxe2. A much rarer approach is h3, seen in 0.9% of games (+0.55 evaluation, 54.8% score), illustrated by h3 e5 Nf3 exd4 Nxd4 Nf6. Both choices leave White with a solid central presence against Black's flexible setup.
