TL;DR

The Nimzowitsch-Larsen Attack opens with 1.b3, preparing Bb2 to control the a1-h8 diagonal. White avoids mainstream theory entirely and bets on flexible development. Loved by Larsen and Carlsen as a way to sidestep preparation and play original chess from move one.

Nimzowitsch–Larsen Attack: A Complete Guide
Nimzowitsch–Larsen Attack - Opening Moves
Summary

The Nimzowitsch-Larsen Attack arises after 1.b3 and falls under ECO code A01. This move prepares a fianchetto of the queen's bishop to b2, from where it will bear down on the central squares and aim toward Black's kingside. As a hypermodern opening, the idea is to influence the center with a piece rather than occupying it with pawns in the classical manner. This naturally allows Black to claim central space, which they usually do with 1...e5 or 1...d5, while 1...Nf6 is another common choice. The Modern Variation, 1...e5, is Black's most popular and ambitious reply, appearing in roughly 45% of games. Black typically constrains the b2 bishop's scope and builds a broad center with both the d- and e-pawns, for instance after 2. Bb2 Nc6 3. e3 d5. The Classical Variation, 1...d5 (about 27% of games), retains the possibility of fianchettoing Black's own bishop to g7 to challenge the one on b2, with White continuing 2. Bb2 or 2. Nf3. The Indian Variation, 1...Nf6 (around 15%), aims to fianchetto to g7 immediately to counter the b2 bishop, but Black must be careful: after 2. Bb2 g6, White can play 3. e4!, threatening to chase the f6 knight, and the greedy 3...Nxe4?? drops the rook to 4. Bxh8. With 46.4 million Lichess games across all rating levels, it is a well-established opening choice.
