King's Indian Defense Fianchetto Variation Puzzle (Rated 1273): Crush Kingside Attack — Fianchetto Tactic
This middlegame puzzle comes from a King’s Indian Defense fianchetto structure where Black’s active pieces create a direct tactical shot against White’s kingside setup. The key idea is to use forcing moves to overload the defender and open lines around the white king and queen. Black’s knight jump creates a discovered attack and a major material swing, turning a balanced-looking position into a decisive advantage through piece activity and tactical pressure.
