Pterodactyl Defense: Fianchetto, Rhamphorhynchus
Overview
Pterodactyl Defense: Fianchetto, Rhamphorhynchus is a variation within the Semi-Open Games family, indexed as 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 8 plies — specifically the moves 1. e4 g6 2. d4 Bg7 3. g3 c5 4. dxc5 Qa5+.
It is a variation of Modern Defense, which itself descends from the root opening King's Pawn Game.
