Russian Game Modern Attack Puzzle (Rated 1485): Win a Pin — Decisive Material Gain

This middlegame puzzle is a classic example of a crushing pin turning into a decisive material win. White’s active rook and queen coordinate against the black king, and the pinned queen creates a tactical weakness that cannot be ignored. The key idea is that when a high-value piece is tied to king defense, a forcing capture can open the position and win material immediately. The position rewards accurate calculation and recognition of overloaded defenders.
