Nimzowitsch-Larsen Attack
1.b3 develops the queen's bishop before a single central pawn — Nimzowitsch's hypermodern dream and Larsen's fighting weapon. The Bb2 stares down the longest diagonal, and every Black central commit becomes a target.
If you want an opening that fights from the very first moves, Nimzowitsch-Larsen Attack is a superb candidate — principled, sharp and endlessly instructive.
After 3.c4 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated.

Plans & pawn structures
- 1The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
- 2Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.
- 3Develop with a purpose: connect the pieces to a concrete plan (a break, a target square, an outpost) instead of making automatic moves.
Typical middlegame structures
The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. No files have opened yet, so this is a manoeuvring struggle: improve your pieces and prepare the pawn break that will open the position on your terms.
Traps & tactical motifs
Every sharp opening has its traps — study the forcing lines around the centre and the f7/f2 squares before playing this in rated games.
Watch the typical motifs: pins against the pinned piece, knight forks after the natural captures, and queen sorties to a2/g2-style squares.
How to Play Against the Nimzowitsch-Larsen Attack
- As Black, strike at the fluid centre immediately with your own central pawn or piece pressure, before the opponent locks it into a shape that favours them.

These openings arrive at the very same board position by a different move order — a transposition. Knowing them lets you steer between systems and recognise when your opponent has walked into familiar territory.
Masters & history
Study plan & who it's for
Comfortable territory for anyone past the beginner stage. A handful of key lines is enough to reach good middlegames, so White players between 800 and 1800 get excellent value here.
Play through the main line above until the piece setup feels natural.
Learn the two or three critical pawn breaks for both sides.
