Queen's Pawn Game
Overview
Queen's Pawn Game is a top-level opening within the Flank Openings family, catalogued as ECO A40 — a starting point from which dozens of named sub-variations branch out.
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 1 ply and takes 1. d4 to reach the canonical position.
The line has 14 documented children — Australian Defense, Benoni Defense: Old Benoni, Borg Defense: Borg Gambit, and others being widely played.
Across every depth of the tree this branch holds 318 documented sub-variations, reflecting decades of analytical work.
