Bent Larsen Chess: Openings, Attacks and World Champion Wins

Bent Larsen was a Danish grandmaster, author and one of the strongest non-Soviet players of the 1960s and 1970s. He was a World Championship Candidate and was famous for imaginative, unorthodox chess. This page studies his games through replay, diagrams and training routes.

Larsen is famous for creative openings, fearless counterattack and wins over World Champions. He is also linked to Larsen’s Opening, the Nimzo-Larsen Attack with 1.b3. His games show how surprise and practical calculation can work at elite level.

Larsen’s Opening is usually associated with 1.b3, developing the bishop to b2 and creating flexible pressure. Larsen used flank ideas as serious weapons, not just tricks. The Kavalek game in the replay lab is the main 1.b3 model.

Yes, Larsen was a Candidate for the World Championship multiple times and reached the semifinal stage three times. He was one of the strongest non-Soviet challengers before Fischer’s peak. His Candidates-cycle games against Portisch and others are central to the page.

Yes, Larsen scored wins over every World Champion from Botvinnik through Karpov across his career. This page includes wins against Petrosian, Fischer, Karpov and Spassky from the supplied PGNs. That is a major authority hook.

Yes, Larsen beat Tigran Petrosian with White in the Second Piatigorsky Cup and also beat Petrosian with Black in the same event. The White win includes a famous queen sacrifice. Both games show that Larsen could trouble even the most resilient defender.

The Larsen–Petrosian game from Santa Monica 1966 is famous for Larsen’s daring queen sacrifice against the World Champion. The attack shows imagination and confidence. It is the first replay and first diagram on this page.

Larsen liked unusual and surprise-based openings including 1.b3, Bird’s Opening, Dutch Defence, Scandinavian Defence, Bishop’s Opening, Philidor ideas and flank systems. He used them to create positions opponents could not solve by memory. The page links to related opening guides.

Yes, Larsen was an aggressive and imaginative counter-attacker. He did not merely seek complications; he often created strategic imbalance first and then attacked. The Petrosian, Kavalek, Ivkov and Portisch games show this clearly.

No, Larsen’s unusual openings worked because he understood the resulting middlegames deeply. His wins over World Champions prove that the ideas were not just surprise weapons. The lesson is to combine originality with calculation.

Start with Larsen–Petrosian 1966 for the queen sacrifice and strongest attacking hook. Then replay Fischer–Larsen 1970, Karpov–Larsen 1980 and Larsen–Spassky 1964. Use the adviser for a theme-based route.

Larsen–Kavalek is a good beginner-friendly attacking route from 1.b3. Larsen–Bednarski also gives a clear Grand Prix-style attacking story. Beginners should focus on how Larsen activates pieces before forcing tactics.

Fischer–Larsen and Karpov–Larsen are best for advanced players. They involve elite-level counterplay, opening choices and endgame conversion. Advanced study should ask why Larsen’s risk was strategically justified.

Larsen–Kavalek is the best 1.b3 model in this replay set. It shows the bishop on b2, flank pressure and a kingside attack. Players of the Nimzo-Larsen Attack should start there.

Larsen–Spassky from Amsterdam 1964 is the key Bird’s Opening model. Larsen used 1.f4 against a future World Champion and won. It is a strong example of a rare opening becoming a serious weapon.

Fischer–Larsen is the strongest Sicilian counterattacking game in this set. Larsen survives pressure and turns the game with active pieces and passed-pawn chances. It is especially useful for players who defend actively.

Karpov–Larsen is the best surprise-opening model because Larsen used an unusual approach against the World Champion. The game shows the point of preparation: not to be weird, but to reach a playable, unfamiliar fight. It is ideal for advanced practical study.

For much of the 1960s and early 1970s, Larsen and Fischer were the strongest non-Soviet players. Fischer ultimately surpassed him, but Larsen’s tournament record and candidate runs were exceptional. Their Palma 1970 game is included because of its historical weight.

Larsen believed in surprise, practical imbalance and taking opponents out of their comfort zones. The goal was not random originality but playable complexity. Club players can learn this principle without copying every rare line.

Yes, Larsen repeatedly beat leading Soviet grandmasters and even won a Candidates playoff against Geller. His results helped prove that non-Soviet players could challenge Soviet dominance. The Geller, Spassky, Petrosian, Taimanov and Karpov games support that theme.

Larsen’s style was imaginative, unorthodox and counterattacking. He liked rook-pawn advances, flank openings and positions where he could set practical problems. His best games combine psychology, opening surprise and tactical calculation.

Yes, Larsen was also a chess author and annotator. His writing emphasized psychology, rare openings and the practical side of chess. That makes him especially relevant for players who want ideas rather than memorized theory.

The main lesson is that originality must be backed by calculation. Larsen used surprise openings to reach positions he understood, then converted imbalance into concrete threats. The diagrams highlight that process.

Larsen naturally fits a tactics and combinations course because his wins often turn surprise into forcing play. The dedicated course card near the bottom links his games to a 39.5-hour tactics course. It is placed immediately before Inguides.

Club players can copy the spirit more safely than the exact move choices. Use unusual openings when you understand the plans and typical tactics. The replay lab gives practical examples before you try them in games.

Daily chess gives time to examine unusual structures and calculate forcing lines. Larsen’s openings are good models because they ask opponents to think independently. Study one game, then try the idea in a slower game.

Study Larsen to learn how imagination, surprise and counterattack can beat even World Champions. His games are fun, practical and full of training value. Start with the Petrosian queen sacrifice, then follow Fischer, Karpov, Spassky and 1.b3.
