Pterodactyl Defense: Central, Benoni Quetzalcoatlus
Overview
Pterodactyl Defense: Central, Benoni Quetzalcoatlus is a specific line in the Semi-Open Games family (ECO B06), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 10 plies and takes 1. e4 g6 2. d4 Bg7 3. c4 c5 4. d5 d6 5. Nc3 Qa5 to reach the canonical position.
The line refines Modern Defense, which traces back to the root opening King's Pawn Game.
