Pterodactyl Defense: Eastern, Anhanguera
Overview
Pterodactyl Defense: Eastern, Anhanguera is a named branch in the Semi-Open Games group of chess theory, classified under ECO B06.
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.
The line arises from 7 plies — specifically the moves 1. e4 g6 2. d4 Bg7 3. Nc3 c5 4. Be3.
In the opening tree, this line branches off from Modern Defense: Modern Pterodactyl, part of the broader King's Pawn Game system.
