The Nimzowitsch–Larsen Attack (also known as Larsen's Opening and Queen's Fianchetto Opening) is a chess opening that begins with the move:
- 1.b3
Frequently, it is reached by transposition, particularly with the move order 1.Nf3 and then 2.b3, as 1.Nf3 prevents Black from playing 1...e5. It is considered a flank opening. The move b3 prepares White's queen's bishop for fianchettoing with Bb2, where it will help control the central squares in hypermodern fashion and put pressure on Black's kingside.
The opening appears within codes A01–A06 in the Encyclopaedia of Chess Openings, with independent lines (such as allowing 1...e5 by not playing 1.Nf3) falling under A01.
