About the Pterodactyl Defense
An offbeat system with ...g6, ...Bg7, ...c5 and an early ...Qa5. Black hits the dark squares and the c3 knight.
The g7 bishop and the queen on a5 both pressure c3.
Black sometimes gives up the bishop with ...Bxc3+ to damage White's pawns.
Without the dark-squared bishop, Black's king can be weak, so be careful.
