Nimzo-Larsen Attack report from your own games

The Nimzo-Larsen Attack begins with 1.b3, immediately preparing to fianchetto the queen's bishop to b2, where it will control the long a1-h8 diagonal. The opening is named after Aron Nimzowitsch, who developed the hypermodern philosophy behind it, and Bent Larsen, who used it extensively in elite competition in the 1960s-70s. Rather than occupying the center with pawns immediately, White uses the b2 bishop and flexible pawn structure to fight for central control from the flanks.

After 1.b3 Bb2, White's plan depends on Black's response. The typical setup involves Nf3, e3, and eventually d4 or d3 with a fianchettoed bishop creating pressure along the long diagonal. The b2 bishop eyes the e5 and d4 squares and supports f2-f4 in attacking setups. White keeps the center flexible, avoiding commitments until Black reveals their setup. Against e5 or e6, White often plays e4; against d5, White may use c4 to challenge. The hypermodern strategy is to undermine the center rather than occupy it.

Bent Larsen was one of the most creative players of his era and used 1.b3 regularly at the highest level, including in his match against World Champion Boris Spassky. Larsen valued the practical advantages: opponents were forced out of preparation immediately, the position demanded original thinking rather than memorized theory, and the resulting middlegames rewarded understanding over rote knowledge. His famous loss to Spassky in the 1970 Match of the Century (10 wins in a row for Spassky) did not diminish the opening's credibility — it was Spassky's exceptional form, not a flaw in 1.b3.

A common practical trap arises against 1.b3 e5 2.Bb2 Nc6 3.e3 if Black plays 3...d5 4.Bb5 Bd7?? (a routine developing move). White plays 5.Nf3 and if 5...f6?? trying to support e5, White responds 6.Bxc6! Bxc6 7.Nxe5! fxe5 8.Qh5+, winning the pawn and creating a devastating attack. The aggressive potential of the Bb2-Nf3 combination creates threats that look innocuous but punish passive play severely — a hallmark of Nimzowitsch's original hypermodern philosophy.
