Pterodactyl Defense: Fianchetto, Queen Pteranodon
Overview
Pterodactyl Defense: Fianchetto, Queen Pteranodon is a specific line in the Flank Openings family (ECO A40), arising from a recognised theoretical position.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
It is reached after 10 plies of play, with the move sequence 1. d4 g6 2. c4 Bg7 3. Nc3 c5 4. d5 Bxc3+ 5. bxc3 Qa5.
The line refines Queen's Pawn Game: Modern Defense, which traces back to the root opening Queen's Pawn Game.
