Nimzo-Larsen Attack: all variations and ECO codes

18 named lines across 2 ECO codes (A01–A06). Source: the CC0-licensed lichess.org opening database.

The idea

White fianchettoes the queen’s bishop before touching a single central pawn, aiming the diagonal at e5 or g7 from the very first move. Like the English Opening, it stays deliberately flexible about the center for as long as possible rather than committing to a fixed structure early.
