English, 1...Nf6 (Anglo-Indian defense)

The Anglo-Indian Defence arises after 1.c4 Nf6. ECO code: A15.

Overview

With 1...Nf6, Black responds to the English Opening flexibly, keeping options open for various pawn structures. This move can transpose into the Queen\'s Indian Defence, Nimzo-Indian Defence, King\'s Indian Defence, or Grünfeld Defence after a subsequent d4 by White.

Strategic Themes & Plans

Black develops a piece and waits to see White's intentions before committing to a pawn structure. The position is one of the most important crossroads in opening theory, with the game's character entirely dependent on subsequent moves by both players.
