By pinning the Nc3, Black does two things: threatens to double White's pawns (after ...Bxc3) and slows down e4. White must decide whether to break the pin (a3, Bd2, Qc2) or accept doubled pawns. Either way, Black gets either doubled c-pawns to target or a bishop pair in an open game. Stockfish evaluates the position at just +0.24 — the lowest of these five defenses — with best play continuing g3 d5 Bg2 O-O: Black develops naturally and castles.
What White will play against you
Across 4,479,843 games, White has six established systems:
- Bd2 — the safest (911,594 games, White 47.6%); avoids doubled pawns.
- Nf3 — flexible development (790,516 games, White 51.0%).
- Bg5 — pins your knight now (771,204 games, White 50.3%).
- a3 — forces the bishop to commit immediately (608,280 games, White 48.6%).
- Qc2 — prevents doubling and supports e4 (544,265 games, White 51.8%).
- e3 — solid but passive (386,693 games, White 51.3%).
Notably, White's worst results come from Bd2 (47.6%) and a3 (48.6%) — the lines that avoid structural damage.
How to play as Black
The Stockfish best continuation from the diagram: White plays g3, Black responds ...d5, White develops Bg2, Black castles ...O-O. This is the template: hold the pin as long as useful, establish a pawn on d5, and castle quickly. After castling, you typically choose between: (1) capturing ...Bxc3 when it actually doubles the pawns, (2) retreating ...Be7 to keep the bishop, or (3) playing ...d5 + ...c5 to fight for the center directly. The Nimzo rewards understanding when to give up the bishop for the knight, not reflexively doing it every game.

Frequently asked questions
Why is the Nimzo-Indian considered so sound?
The +0.24 engine evaluation is the lowest among Black's main 1.d4 defenses. The ...Bb4 pin creates immediate structural tension that gives Black concrete compensation without needing to memorize long theory.
Should Black always capture ...Bxc3 in the Nimzo-Indian?
No — it depends on White's structure and your plan. Capturing doubles White's pawns and gives Black a target, but surrenders the bishop pair. The decision should be concrete, not automatic.
What's the difference between Nimzo-Indian and Queen's Indian?
In the Nimzo, Black pins the Nc3 with ...Bb4 after 3.Nc3. In the Queen's Indian, White plays 3.Nf3 instead, so there's no knight to pin — Black plays ...b6 for the fianchetto. They're related systems often prepared together.
Which White system is the most dangerous in the Nimzo-Indian?
By Lichess score, Qc2 (51.8%) gives White the best practical results, followed by Nf3 (51.0%) and Bg5 (50.3%). Bd2 (47.6%) is White's safest but most passive try.
