Scandinavian Defense Pin Beginner Puzzle (Rated 1464): Spot a Mate in 1 — Pin Tactic

This puzzle is a classic middlegame mating pattern where the key idea is an absolute pin that strips the king of its escape squares. When a defender is pinned to the king, even a seemingly ordinary queen move can become decisive because the pinned piece cannot capture or block. The position also shows how king safety can outweigh material: once the attacking pieces coordinate on the kingside, the defense collapses immediately.
