Queen's Indian Accelerated
Overview
Queen's Indian Accelerated is a named branch in the Flank Openings group of chess theory, classified under ECO A50.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
It begins with 4 plies and takes 1. d4 Nf6 2. c4 b6 to reach the canonical position.
In the opening tree, this line branches off from Indian Defense: Normal Variation, part of the broader Queen's Pawn Game system.
