Pterodactyl Defense Fianchetto (1.d4 g6 2.c4 Bg7 3.Nc3 c5 4.d5 Qa5) Chess Puzzles

The “pterodactyl defense fianchetto” is a Pterodactyl Defense line where Black commits to a kingside fianchetto—most characteristically by developing the bishop to g7 after the Pterodactyl-style pawn/knight setup. For an intermediate player, the defining feature is that Black’s dark-squared bishop on g7 becomes the long-range piece that pressures the center and often supports a later ...e5 or ...d5 break depending on White’s setup.
