The Pterodactyl Defense is a unique and aggressive opening that aims to disrupt the opponent's plans by fianchettoing the king's bishop and sacrificing a bishop for a queen-side attack. The opening begins with a pawn move to d4, followed by g6, allowing Black to fianchetto their dark-squared bishop. White responds with c4, establishing control over the center and preparing for a potential queen-side expansion. Black continues with Bg7, developing their bishop to a strong diagonal. White plays Nc3, developing a knight and preparing to castle. Black then plays c5, challenging White's central pawn and aiming to undermine their pawn structure.
