Pterodactyl Defense: Central, Benoni Beefeater Pterodactyl
Overview
Pterodactyl Defense: Central, Benoni Beefeater Pterodactyl 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.
The line arises from 12 plies — specifically the moves 1. d4 g6 2. c4 Bg7 3. Nc3 c5 4. d5 d6 5. e4 Bxc3+ 6. bxc3 Qa5.
The line refines Queen's Pawn Game: Modern Defense, which traces back to the root opening Queen's Pawn Game.
