Nimzo Larsen Attack Clearance in Chess

The Nimzo Larsen Attack Clearance is a tactical motif where White clears a key line or square so an attacking piece can act with tempo in the Nimzo-Larsen Attack. A defining feature is the early kingside pressure after moves like 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.b3, where White often needs to remove a blocker to unleash an attack. The “clearance” happens before the decisive strike, so the opponent’s pieces can’t interpose effectively.
