Openings Against D4 Puzzle (Rated 1103): Pin — Winning Tactic

This King’s Indian Defense puzzle illustrates how a pin can turn an apparently active position into a tactical liability. Black’s bishop is tied to the queen, while White’s king remains in the center and several pieces lack mobility. The key idea is to increase pressure with a forcing move, exploit the exposed king, and use the pin to attack a hanging piece. The result is a decisive material gain and a strong practical advantage in the middlegame.
