Pterodactyl Defense: Fianchetto, Queen Benoni Pterodactyl
Overview
Pterodactyl Defense: Fianchetto, Queen Benoni Pterodactyl is a named branch in the Flank Openings group of chess theory, classified under ECO A40.
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 8 plies and takes 1. d4 g6 2. c4 Bg7 3. Nc3 c5 4. d5 Qa5 to reach the canonical position.
In the opening tree, this line branches off from Queen's Pawn Game: Modern Defense, part of the broader Queen's Pawn Game system.
