Why the pin matters
White's knight on c3 is the main defender of the e4 square. By pinning it with ...Bb4, Black stops e2-e4 in its tracks and fights for the centre with pieces rather than pawns - the core hypermodern idea, and the one Nimzowitsch built a system around.
If White breaks the pin with a3, Black takes on c3 and White recaptures with the b-pawn. The resulting doubled c-pawns are the permanent feature of most Nimzo-Indian middlegames: White has the bishop pair and a big centre, Black has the better structure and a plan (blockade c4, put a knight on a5 or e4, and target the doubled pawns).
What each White fourth move is trying to do
- 4.e3 (Rubinstein) - the flexible main line. White develops naturally and decides later whether to accept doubled pawns.
- 4.Qc2 (Classical) - the most direct: White prepares to recapture on c3 with the queen and avoid doubled pawns entirely, at the cost of time.
- 4.a3 (Samisch) - White forces the trade immediately and plays for the bishop pair and f3/e4.
- 4.Nf3 - keeps the most options and can transpose to the Queen's Indian or Ragozin.
The whole opening is one long argument: are the two bishops and the big centre worth more than the doubled pawns? The answer depends entirely on whether White can play e4 and open the position. Blockade the centre and Black is better; let it open and the bishops dominate.
Typical Black plans
- Blockade c4 with a knight on a5 or with ...b6 and ...Ba6, hitting the pawn directly.
- Plant a knight on e4, backed by ...d5 and ...f5 (the Nimzo-Dutch setup).
- Play ...c5 and ...d5 to fix the doubled pawns as targets in the endgame.
Frequently asked questions
Why is the Nimzo-Indian so highly regarded?
It is theoretically sound, scores well at every level, and produces positions where understanding beats memorisation. Almost every world champion since Capablanca has played it, and 3.Nf3 is popular for White largely as a way to avoid it.
What happens if White avoids the Nimzo with 3.Nf3?
Then ...Bb4 is not available with the same effect, so Nimzo players need a second defence: usually the Queen's Indian (3...b6), the Bogo-Indian (3...Bb4+) or the Ragozin/QGD (3...d5). Prepare this pair together - you will face 3.Nf3 constantly.
