How to beat the Nimzowitsch Defense

1.e4 Nc6: Black develops the queen's knight first and keeps every option open: ...e5 for an open game, ...d5 for a Scandinavian or French-style fight, ...d6 for a Pirc-like set-up. It looks odd, but it was one of the most awkward defences for the top titled players to face: in our sample they scored only 52% as White against it in 53 games, 15 points below their 67% average as White.

Three plans that work

1. Play 2.Nf3 and invite 2...e5

2.Nf3 is the practical choice. If Black answers 2...e5, you're in a normal open game (Italian, Ruy Lopez, Scotch) and the surprise is gone. Lichess calls 2.Nf3 lines without ...e5 the Declined Variation: titled players scored 62% as White in 13 games, against 46% in 12 games filed as the plain Nimzowitsch Defense (1.e4 Nc6 and 2.d4 lines without a sub-name). Both samples are small, so read it as a hint.

2. Against 2...d6, build the big centre and kick the knight

After 2.Nf3 d6 (the Williams Variation) 3.d4 Nf6 4.Nc3, you have the classical e4/d4 centre and Black's c6 knight blocks the c-pawn, so ...c5 is hard to arrange. Develop with Be2 and O-O, and when the moment is right, d4-d5 gains space with tempo on the knight.

3. If you play 2.d4 and meet ...d5, grab space with 3.e5

2.d4 d5 3.e5 gives you a French-style space edge where Black's knight on c6 gets in the way of the usual ...c5 break. Support d4 with c3 and Nf3, develop with Be2 or Bd3 and O-O, and don't hurry: Black has to find a plan, you don't.

A line to play

The pitfall

Treating 1...Nc6 as a free tempo. Its fans know the tricks, and the plain 1.e4 Nc6 / 2.d4 games were the titled players' worst bucket in our sample (46% as White in 12 games). Don't push your centre pawns too far before your pieces are out: Black's whole plan is to hit an overextended d4 or e5 with ...d6, ...f6 or ...Bg4 and ...e5.
