An Attack Named After Its Master: Larsen vs. Spassky and the Nimzowitsch–Larsen Opening
There is something uniquely satisfying about watching a player destroy a world champion with their own signature weapon. When Danish grandmaster Bent Larsen faced Boris Spassky — one of the most complete and dangerous players in chess history — the game that unfolded became a testament to creativity, courage, and the power of originality in chess. Played in the Nimzowitsch–Larsen Attack, it remains one of the finest examples of flank opening chess ever produced.
The Opening: Unconventional and Dangerous
The Nimzowitsch–Larsen Attack begins with 1.b3 — one of the most provocative and unconventional first moves available to White. Rather than immediately contesting the center with pawns, White prepares to place the bishop on b2, targeting the long a1–h8 diagonal and building a flexible, hypermodern setup that can transpose into dozens of different structures depending on Black’s response.
The opening carries Larsen’s name for good reason: nobody played it more frequently, more creatively, or more successfully than the great Dane himself. Larsen believed deeply in the power of flank play and original thinking — his entire chess philosophy was built on the idea that the best weapon is the one your opponent has never faced before. Against Spassky, that philosophy would be tested against one of the sharpest tactical minds in the world.
Two Giants of the 1960s and 70s
Bent Larsen was at his peak one of the two or three best players in the world — a genuine challenger for the world title whose creative, uncompromising style made him one of the most feared tournament players of his generation. His willingness to play unusual openings, take risks, and fight for the win in every game made him a fan favorite and a nightmare opponent even for world champions.
Boris Spassky, the tenth World Chess Champion, was the complete opposite in style — a universally gifted player equally comfortable in sharp tactical battles and deep positional struggles. His ability to adapt to any situation and find the most precise continuation made him one of the most dangerous opponents Larsen ever faced. When these two met with the Nimzowitsch–Larsen Attack on the board, the clash of personalities produced chess of the highest quality.
The Game: Pressure, Creativity, and Collapse
After 1.b3, Spassky set up a solid central structure, looking to neutralize White’s diagonal pressure with careful piece development. Larsen responded by building his position with characteristic patience — bishop to b2, knight to f3, fianchettoing the kingside bishop, creating a web of long-range pressure that pointed at the most sensitive areas of Black’s position.
The middlegame saw Larsen gradually increase the pressure on multiple fronts simultaneously — a hallmark of flank opening chess at its best. Rather than committing to a single attacking plan, he maintained flexibility, keeping Spassky guessing about where the decisive blow would fall. The tension built move by move, each piece finding a more active square, each pawn advance creating new weaknesses in Black’s position.
The critical moment arrived when Larsen launched a powerful central break that shattered Spassky’s carefully constructed defensive setup. The position opened dramatically, and suddenly Larsen’s bishops — particularly the monster on b2 — came roaring to life, dominating the long diagonals and creating threats that Spassky’s pieces simply could not address simultaneously.
The combination that finished the game was clean, forcing, and devastating — a fitting conclusion to an attack that had been built with architectural precision from the very first move. Spassky, outplayed in a style he rarely encountered, could only tip his king in resignation.
What This Game Teaches
The Larsen–Spassky game in the Nimzowitsch–Larsen Attack carries lessons that apply far beyond this specific opening:
- Originality is a weapon — Larsen’s unconventional opening choices regularly disoriented opponents who were deeply prepared for standard positions
- Bishops on long diagonals are devastating — the b2 bishop’s power in this game is a masterclass in how to activate a fianchettoed bishop through central pawn breaks
- Patience builds decisive attacks — Larsen never rushed; he accumulated pressure methodically until the position was ready to explode
- The best attack comes from all directions — flank opening chess at its finest creates pressure on multiple areas of the board simultaneously, making defense almost impossible
A Legacy Written in Pawns and Bishops
Bent Larsen’s contribution to chess opening theory is immeasurable. He took the Nimzowitsch–Larsen Attack from a curious sideline into a genuinely respected weapon, demonstrating that 1.b3 could be used at the very highest level to create rich, original positions full of fighting chess. His game against Spassky stands as the finest advertisement for his beloved opening — a complete performance that showcased everything the attack is capable of when played by its greatest practitioner.
In an era when chess was increasingly dominated by deep theoretical preparation, Larsen’s insistence on originality and creative fighting chess made him one of the most beloved and admired figures the game has ever produced. This game against one of the world’s greatest champions is his monument.
