The Indian Variation of the Nimzowitsch-Larsen Attack arises after 1.b3 Nf6. ECO code: A01.

Overview

With 1...Nf6, Black develops a piece flexibly, keeping options open for various central pawn structures. The position can transpose into numerous systems depending on subsequent play.

Main Lines

White continues 2.Bb2, and play typically develops along one of several paths:

• 2...g6 – Leading to King\'s Indian Defence-type structures

• 2...e6 – Leading to Queen\'s Indian Defence or Nimzo-Indian Defence-type structures

• 2...d5 – Transposing toward the Classical Variation of the Nimzowitsch-Larsen Attack

Strategic Themes & Plans

The Indian Variation leads to flexible, manoeuvring positions. White maintains the core plan of long-diagonal pressure from b2 while adapting to Black's chosen structure. Both sides enjoy considerable strategic freedom in the early stages.
