Passed Pawn Puzzle (Rated 972): Win Material — Pin
This middlegame puzzle is built around a tactical refutation of an overextended attack. Black appears to have dangerous pressure near the white king, but the attacking queen has moved into a vulnerable square. White can exploit the coordination of the queen, bishop, and rook by removing the most valuable attacker first. The resulting sequence transforms a material deficit into a decisive advantage, while the pinned knight and exposed rook show how tactical geometry can outweigh apparent king-side threats.
