Skewer Puzzle (Rated 1238): Spot a Pin — Rook Gain
This middlegame puzzle highlights how a pin can turn a seemingly active position into a material-winning opportunity. Black’s queen restricts the bishop while also creating pressure against a rook that has no safe retreat. White has extra material, but piece activity and king safety matter more in the moment. The key idea is to recognize that the trapped rook cannot escape and that the pin prevents a useful defensive resource. Strong tactical play often begins with identifying overloaded and immobilized pieces.
