Nimzo-Indian Defence: Hyper-Modern Chess Opening
Nimzo-Indian Defence
Definition
The Nimzo-Indian Defence is a hyper-modern chess opening that arises after the moves 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4. Black immediately pins the knight on c3, discouraging the natural advance 4. e4 and aiming to control the centre with pieces rather than pawns. The opening is classified in the ECO as codes E20–E59.
Origins & Historical Significance
The opening was popularised by the Latvian-Danish grandmaster Aron Nimzowitsch during the 1920s and 30s as a practical embodiment of his “hyper-modern” ideas—inviting White to occupy the centre and then attacking it. Since then it has become one of Black’s most reliable replies to 1.d4, repeatedly adopted in World-Championship matches by Capablanca, Botvinnik, Smyslov, Petrosian, Karpov, Kasparov, Anand, and Carlsen.
Main Move-Orders & Transpositions
The typical sequence is:
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4
Black can also reach the Nimzo-Indian via 1…e6 move-orders (1.d4 e6 2.c4 Bb4+) to sidestep certain openings such as the Trompowsky. Conversely, if White avoids 3.Nc3, play may transpose into the Queen’s Indian (3.Nf3 b6) or Bogo-Indian (3.Nf3 Bb4+).
Strategic Themes
- Doubled c-pawns: After …Bxc3+, Black often inflicts doubled c-pawns on White, aiming to target them in an endgame while gaining dynamic play in the middlegame.
- Bishop-pair vs. structure: White usually keeps the bishop pair; Black obtains structural weaknesses to attack. A recurring dilemma for White is whether the bishops outweigh the pawn weaknesses.
- Control of the e4-square: The pin on Nc3 and pressure on d4 can make it difficult for White to break with e4. Black’s knights frequently occupy e4 or c5.
- Flexibility: Black can choose set-ups with …c5, …d5, …b6, or …f5 depending on the variation.
Principal White Systems
- 4.Qc2 (Classical Variation) – Protects the knight, discouraging …Bxc3+ and preparing e4.
- 4.e3 (Rubinstein) – A solid line, often leading to Carlsbad or hanging-pawn structures.
- 4.a3 (Sämisch) – Immediately asks the bishop to decide; usually 4…Bxc3+ 5.bxc3.
- 4.Bg5 (Leningrad) – Pins the f6-knight and can transpose to a Queen’s Gambit with colours reversed.
- 4.Nf3 (Kmoch) – Sidelines theory, eyeing a later g2–g3 and Bg2.
- 4.f3 and 4.g3 – More specialised systems, the former preparing e4, the latter aspiring to a Catalan-style set-up.
Typical Plans for Black
- Playing …d5 and …c5 to attack the centre with an isolated-queen-pawn or hanging-pawns structure.
- Light-square strategy: Place a knight on e4 or c5, exchange White’s dark-squared bishop, and target c4/c3.
- Queenside expansion: …b6 followed by …Bb7, …c5, and sometimes …b5 to seize space.
- Kingside play: In certain lines (e.g., Hübner Variation of the 4.Qc2 line) Black uses …f5 to start a pawn-storm.

- Smyslov – Botvinnik, World Championship 1954, Game 9: Botvinnik’s dynamic handling of the Rubinstein Variation set a strategic model for Black.
- Carlsen – Caruana, Sinquefield Cup 2014: A modern treatment of the 4.Qc2 line, ending in a tense draw after deep manoeuvring.
