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
- •After 1.b3 and 2.Bb2, develop with Nf3, e3, and d4 for a solid Queen's Gambit-like structure with the hypermodern bishop twist
- •Use the Bb2 bishop to support e4 or d4 central breaks — the bishop's diagonal becomes the highway for these advances
- •Consider the dual fianchetto setup with g3-Bg2 added to b3-Bb2 for maximum diagonal pressure on both long diagonals
- •After completing development, look for e4 advance to open the Bb2 diagonal fully — this is often the decisive central break
- •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
- •After 1.b3, claim the center immediately with 1...d5 or 1...e5 — don't allow White free piece activity without central compensation
- •After Bb2, develop with standard piece setups: Nf6, e6, Bc5 or Bd6 — normal development is fully sufficient against hypermodern openings
- •Counter the Bb2 diagonal by placing a pawn on d5 and keeping it there — this neutralizes the bishop's main line of force
- •Consider the mirror setup with 1...b6 and ...Bb7 — meeting hypermodern with hypermodern creates interesting diagonal battles
- •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.
Main Line (1...d5 2.Bb2 Nf6 3.Nf3)
1.b3 d5 2.Bb2 Nf6 3.Nf3 e6 4.e3 Be7 5.d4
The most popular continuation. After Black's classical development, White builds a solid d4-e3 pawn structure and develops harmoniously. The resulting position resembles the Queen's Indian Defense with reversed colors but White has an extra tempo. The Bb2 bishop becomes the main strategic weapon in the long-term middlegame.
Aggressive (1...e5 2.Bb2 f6!?)
1.b3 e5 2.Bb2 Nc6 3.e4 Nf6
Black immediately claims the center aggressively with e5. After 2.Bb2 Nc6 3.e4, the game transitions into King's Pawn Opening territory with an unusual bishop placement. White maintains the Bb2 setup while fighting for central space. The resulting positions are sharp and often lead to asymmetric battles.
Dutch System (1...f5)
1.b3 f5 2.Bb2 Nf6 3.e3 e6 4.c4
Against the Dutch Defense, the Nimzo-Larsen creates unique pressure. After c4, White challenges Black's central control and the Bb2 bishop targets the queenside. Black's f5 pawn creates attacking chances but leaves the kingside potentially weakened. White uses c4- d4 to open lines for the bishop.
Symmetrical (1...b6)
1.b3 b6 2.Bb2 Bb7 3.e3 e6 4.Nf3 Nf6
Black mirrors White's setup immediately. After b6-Bb7, both sides have fianchettoed queenside bishops on the long diagonal. The resulting position requires precise understanding of who benefits from the diagonal clashes. White tends to have slightly more flexibility due to moving first.
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?
Bent Larsen: Chess Innovator
Danish Grandmaster Bent Larsen was one of the greatest chess innovators of the 20th century and the opening's primary champion. Larsen used 1.b3 to sidestep all theoretical opening preparation and create unique strategic battles on his own terms. He proved that hypermodern ideas combined with practical traps make the Nimzo-Larsen Attack fully competitive at the highest levels.
Control Without Occupation
The Bb2 bishop is the strategic foundation of the Nimzo-Larsen Attack — it controls the center without occupying it. This hypermodern philosophy allows White to be flexible and respond to Black's setup rather than committing prematurely. The bishop's long diagonal remains active throughout the entire game, often becoming the decisive piece in the endgame.
Avoids All Mainstream Theory
After 1.b3, your opponent cannot use the first 20 moves of preparation they've memorized. The Nimzo-Larsen immediately creates positions that neither player has studied deeply. This levels the playing field—sometimes literally—as even Grandmaster-level preparation is useless in positions arising from 1.b3.
Carlsen and Nakamura Approved
Magnus Carlsen and Hikaru Nakamura have both used the Nimzo-Larsen Attack in serious competitive games, demonstrating that the opening maintains full practical validity at the elite level. Their endorsement proves that 1.b3 is more than a club-level surprise weapon — it's a legitimate strategic choice for the world's best players.
Common Traps
Watch out for these dangerous tactical pitfalls
The d5 Pawn Undermining Trap
1.b3 d5 2.Bb2 Nc6 3.e3 e5 4.Bb5 Bd6 5.f4 Qg5 6.Nf3 Qxg2 7.Rg1 Qh3
White aggressively pushes f4 to undermine Black's center. Black's queen sortie is dangerous and creates a very sharp position.
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
1.b3 is purely about placing the bishop on b2 — always play 2.Bb2 on your second move regardless of Black's response.
After Bb2, develop with Nf3, e3, and d4 for a solid, complete setup. Don't rush to create tactics before development is complete.
The Bb2 bishop's effectiveness depends on the a1-h8 diagonal being open — use e4 or d4 advances to open this diagonal at the right time.
Consider adding g3-Bg2 to create a dual diagonal battery on both long diagonals — this is White's most powerful Nimzo-Larsen setup.
As Black, the correct response to 1.b3 is immediate central play with 1...d5 or 1...e5 — never be passive against hypermodern openings.
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.

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.
