Pterodactyl Defense: Sicilian, Siroccopteryx
Overview
Pterodactyl Defense: Sicilian, Siroccopteryx 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 9 plies and takes 1. e4 g6 2. d4 Bg7 3. Nc3 c5 4. Nf3 Qa5 5. Bc4 to reach the canonical position.
The line refines Modern Defense: Modern Pterodactyl, which traces back to the root opening King's Pawn Game.
