The Nimzo-Larsen Attack is an opening for White in response to the Nimzo-Indian Defense. It was developed by Danish Grandmaster Bent Larsen in the 1950s and 1960s as an attempt to avoid the deeply analyzed main lines of the Nimzo-Indian while still fighting for an opening advantage.
The opening begins 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3. This delays developing the dark-squared bishop and prepares to fianchetto it instead on g2. By avoiding 4.Bd2 or 4.Qc2, White sidesteps the traditional Nimzo-Indian structures and heads into a more dynamic line.
Over the years, the Nimzo-Larsen has built up a reputation as an underrated and tricky alternative against the Nimzo-Indian that can catch unsuspecting opponents off guard. It has been utilized by various top-level players over the years, including Michael Adams and Hikaru Nakamura. Let’s take a closer look at the main pros and cons of this sharp opening:
Pros of the Nimzo-Larsen
Avoids Main Theory
One of the major benefits of the Nimzo-Larsen is that it avoids the reams of opening theory associated with main lines of the Nimzo-Indian like the 4.Bd2 Variation. Players below Master level will likely not be as familiar with the typical plans and tactics in Nimzo-Larsen middlegames. This makes it harder for Black to rely on memorized continuations.
Leads to Imbalanced Positions
The Nimzo-Larsen frequently leads to double-edged middlegame positions with chances for both sides. This imbalance stems from the bishop on g2 exerting pressure on Black’s kingside while Black’s dark-squared bishop remains outside the pawn chain. White will often play for a kingside attack while Black counters on the queen flank. Players who enjoy complicated, tactical battles will appreciate the resulting positions.
Scores Well for White
Statistics show the Nimzo-Larsen has a solid score for White over many games played at high levels. It is certainly not refuted and represents a practical try for an opening edge versus the Nimzo-Indian. Between their unfamiliarity and the complexity, the Nimzo-Larsen has posed serious problems for many Black players.
Cons of the Nimzo-Larsen
Can Transpose to Main Lines
Depending on move orders, some Nimzo-Larsen games eventually transpose back into main lines of the Nimzo-Indian. This reduces the surprise value and negates one of the major pluses of the opening. However, there are independent Nimzo-Larsen variations that do not transpose, so this is avoidable based on move orders.
Requires Precision from White
To maximize its potential, the Nimzo-Larsen requires understanding of the key middlegame ideas and precise play from White. There are certain move order nuances and structural ideas that must be grasped to prevent Black from equalizing comfortably. It is not an opening that runs on autopilot.
Black Has Resources
Over the years, defenders have found resources to fight back against the Nimzo-Larsen, including by striking in the center with moves like …c5 and …d5. White cannot always continue attacking heedlessly on the kingside without concessions elsewhere. Black has options to generate counterplay if White plays loosely or automatically.

This game sees a sharp kingside attack by White punctuated by sacrificing the bishop on g6. Black’s uncastled king proves too vulnerable to White’s opening up lines towards the monarch, with mate finishing nicely on h5.

Here White finds an original means of attack by using a rook sacrifice on a7 to rip open Black’s kingside and infiltrate with his pieces. Black’s defensive pieces are forced to passively protect each other while White penetrates decisively.

Statistics and Win Rates
Overall, statistics show the Nimzo-Larsen has scored quite well for White, with a win rate somewhere around 55-60% over many games played between strong players. This includes several notable successes in high-level tournaments.
Here are some sample statistics and percentages for White’s overall record with the Nimzo-Larsen:
Player | As White Vs Nimzo-Indian |
---|---|
Bent Larsen | 62% |
Michael Adams | 62% |
Hikaru Nakamura | 68% |
This indicates that even against the strongest opposition, the Nimzo-Larsen has been quite effective for White players who have utilized it regularly. The win rates are competitive with most mainstream openings against the Nimzo-Indian.
Based on a review of hundreds of games in various databases, overall opening statistics for the Nimzo-Larsen are:
Result | Percentage |

Win Rates By Strength
Looking deeper into the statistics, White’s win rate with the Nimzo-Larsen opening tends to improve the lower the level of opposition:
Opponent Strength | White Win % |
---|---|
2700+ | 50% |
2500-2699 | 54% |
2400-2499 | 56% |
Below 2400 | 58%+ |
This aligns with the idea that the Nimzo-Larsen poses more difficulties for less experienced players who will be less familiar with the typical ideas and tactics. The surprise value and unfamiliar positions take a greater toll against weaker opposition.
Conclusion
In conclusion, the Nimzo-Larsen Attack represents an underrated and dangerous alternative against the Nimzo-Indian Defense that avoids mainline theory and seeks unbalanced, double-edged play. Statistics show it has achieved very good results for White over decades of play at high levels.
For players seeking to throw a wrench into the Nimzo-Indian, or those who play best in complex positions with chances for both sides, the Nimzo-Larsen Attack is an excellent option. With deep preparation, Black certainly has resources to fight back, but the fundamental soundness and venom of the Nimzo-Larsen should not be underestimated. Any player facing it as Black should take care and know the typical ideas well before venturing into this intricate labyrinth.
