The Nimzo-Larsen Attack! White prepares to fianchetto the queenside bishop to b2, placing it on the powerful a1-h8 diagonal. This hypermodern approach avoids the central pawn fights of 1.e4 and 1.d4, instead seeking to control the center from afar with pieces. Named after Aron Nimzowitsch and Danish GM Bent Larsen, both legendary opening innovators.
Key Positions to Know
Critical concepts every Nimzo-Larsen Attack player should understand
The Great Bb2 Bishop
After 1.b3 and 2.Bb2, White's bishop controls the long diagonal and pressures both e5 and g7. This bishop is the engine of the entire Nimzo-Larsen strategy — it can't be easily challenged and creates long-term pressure on the opponent's setup throughout the game.
Flexible Central Strategy
Unlike most openings, the Nimzo-Larsen doesn't commit to a specific pawn center immediately. White can play e3-d4 (a QGD-like setup), e4-d3 (a King's Indian Attack), or f4 for an aggressive Dutch-style setup. This flexibility makes it hard for Black to prepare specifically.
Pressure on d5
The Bb2 bishop most commonly targets the d5 pawn or the d5 square. If Black plays ...d5, the bishop immediately targets it from afar. White often reinforces this pressure with Nf3 and develops naturally, while the bishop creates a permanent, quiet threat that is difficult to neutralize.
Strategic Plans
♔White's Plans
- •Desenvolver o bispo em b2 activamente ao longo da diagonal longa
- •Jogar e3 ou e4 para contestar o centro quando oportuno
- •Usar o bispo em b2 para pressionar o centro do Preto
- •Criar contrajogo no flanco da dama com c4 e d4
- •In the endgame, the Bb2 bishop remains active — use it to restrict Black's counterplay and create passed pawns
- •Castle kingside and use the c4-d4 pawn structure to challenge Black's central pawn formation
- •Against Dutch Defense (1...f5), use c4 early to immediately challenge Black's e4 square ambitions
♚Black's Plans
- •Tomar espaço central imediatamente com ...e5 ou ...d5
- •Não se deixar intimidar pelo bispo em b2 — neutralizá-lo com ...d5
- •Desenvolver activamente e não ficar na defensiva
- •Usar o par de bispos para neutralizar o bispo em b2 do Branco
- •Use ...c5 at the right moment to challenge d4 and open files for piece activity
- •Don't be intimidated by the unusual move order — treat the resulting positions as standard Queen's Gambit-like structures
- •In the middlegame, target the Bb2 bishop with ...Na5 or ...Ba6 exchanges to reduce White's long-term pressure
- •Use ...Ne4 occupations when available — the central knight outpost balances White's bishop diagonal dominance
Key Variations
Explore the most important branches and transpositions in the Nimzo-Larsen Attack.
Versus 1...e5
Contra 1...e5, o Branco continua com 2.Ab2, desenvolvendo o bispo activamente. O jogo pode transporar para a Siciliana Invertida ou outras formações.
Versus 1...d5
Contra 1...d5, o Branco joga 2.Ab2 e depois desenvolve para atacar o centro do Preto. O bispo em b2 pressiona imediatamente o peão d5.
Versus 1...Cf6
Contra 1...Cf6, o Branco pode jogar 2.Ab2 seguido de Cf3 ou e3, transpondo para linhas similares ao Reti ou à Inglesa.
Abordagem Larsen
Às vezes o Branco joga 2.Af3 em vez de 2.Ab2, criando uma diferente estrutura. Esta foi a abordagem favorita do próprio Larsen em muitas partidas famosas.
King's Indian Attack Transposition
1.b3 d5 2.Bb2 Nf6 3.g3 c5 4.Bg2 g6 5.Nf3
White plays g3 and Bg2 after the standard Bb2 development, creating a dual fianchetto setup. After 5.Nf3, the game resembles a King's Indian Attack with an extra fianchettoed queenside bishop. This is one of the most powerful Nimzo-Larsen setups because the double bishop battery creates enormous diagonal pressure.

Why Play the Nimzo-Larsen Attack?
Valor de Surpresa Total
O Ataque Nimzo-Larsen é uma das aberturas menos vistas no xadrez competitivo. Ao jogar 1.b3, o Branco imediatamente sai do caminho das preparações do adversário. A maioria dos jogadores não tem ideia de como responder adequadamente.
Princípios Hipermodernos
Como a Abertura Inglesa e o Reti, o Nimzo-Larsen permite ao adversário construir um centro de peões e depois o ataca de longe. O bispo em b2 exerce pressão constante ao longo da diagonal longa.
Flexibilidade Total
O Branco pode jogar 1.b3 contra qualquer resposta do Preto. Esta flexibilidade absoluta é muito valiosa — o Branco não precisa de estudar respostas específicas a diferentes aberturas.
Amado por Grandmestres Originais
Nimzowitsch, Larsen, e mais recentemente Tigran Petrosian e outros GM's adoptaram este sistema. É uma abertura completamente legítima usada nos mais altos níveis.
Common Traps
Watch out for these dangerous tactical pitfalls
Armadilha do Bispo Longo
Se o Preto não neutralizar cedo o bispo em b2, o Branco pode criar ameaças devastadoras ao longo da diagonal longa, especialmente após a abertura do centro.
The Diagonal Discovery Trap
1. b3 e5 2. Bb2 Nc6 3. e3 Nf6 4. Nf3 e4?? 5. Ng5 d5 6. d3 exd3 7. Bxf6
After the aggressive 4...e4?? (trying to make the Nf3 retreat), White plays 5.Ng5! threatening Nxf7 and Bxf6. After 5...d5 6.d3 exd3, White plays 7.Bxf6! and the Bb2 diagonal creates devastating threats. The e4 pawn push was premature and actually helped White open lines for the diagonal bishop.
The Long Diagonal Checkmate Threat
1. b3 d5 2. Bb2 Nf6 3. Nf3 c5 4. e3 e6 5. c4 Nc6 6. cxd5 exd5 7. d4 cxd4 8. exd4 Bg4?? 9. Bb5
After the careless Bg4 (pinning Nf3), White plays 9.Bb5! This attacks the Nc6 and simultaneously reveals the Bb2 battery's power. If 9...Bd7, White plays 10.Bxc6 Bxc6 11.Ne5 and the Bb2 bishop now controls the entire long diagonal with devastating effect. Black's Bg4 pin backfired by allowing White to activate the full diagonal battery.
Beginner Tips
O bispo em b2 é a sua peça principal — mantenha-o activo
Use o Nimzo-Larsen como arma surpresa em torneios
Aprenda a transpor para outras aberturas quando necessário
Estude as partidas de Larsen para entender o sistema profundamente
Não tente forçar o ataque — deixe o bispo fazer o trabalho
Watch for Ne5 or Ng5 leaps after Bb2 is established — these knight moves often create tactical fireworks that complement the bishop's diagonal pressure.
Study Larsen's games with 1.b3 to understand the hypermodern philosophy: controlling the center from the flanks is the entire concept.
In blitz chess, the Nimzo-Larsen's theoretical novelty creates immediate practical problems for opponents — use the clock advantage from their longer thinking time.

Frequently Asked Questions
Common questions about Nimzo-Larsen Attack analysis
Famous Games
In the famous USSR vs Rest of World 1970 match, Larsen was demolished by Spassky in one of the most beautiful attacking games ever played from a 1.b3 position. Spassky's Ng4 queen sacrifice and subsequent mating attack became legendary. While Larsen lost this game, his courage in playing 1.b3 against World Champion Spassky cemented the opening's status as a serious weapon.
Larsen faced Fischer in the famous 1971 Candidates Match and deployed his beloved 1.b3. Fischer won convincingly but the game demonstrated Larsen's commitment to the opening even against the strongest player in the world. The match series (which Fischer won 6-0) remains one of the most discussed in chess history, keeping the Nimzo-Larsen in the spotlight.
Carlsen deployed 1.b3 against Anand in a high-stakes blitz game, demonstrating that the Nimzo-Larsen creates genuine problems even for former World Champions. Carlsen's masterful handling of the resulting complex positions showed that the opening's flexibility rewards players who understand hypermodern principles deeply.
Nakamura used the Nimzo-Larsen to stunning effect against Aronian in a classical tournament game. The game featured White's Bb2 bishop playing a decisive role in both the middlegame and endgame. This was one of Nakamura's early demonstrations that 'creative' openings can work at the elite level when combined with deep positional understanding.
