Pin Puzzle (Rated 1245): Win with a Pin — Endgame Tactics

This chess endgame puzzle shows how a single tactical idea can outweigh material. White’s pieces look active, but Black has a forcing resource that creates a pin-based threat and a tactical fork against the king and queen. In classical chess, these moments often decide the game because the king’s limited mobility makes every tempo matter. The key lesson is to look for checks first, then examine whether a pinned piece can be exploited to win material or force a decisive simplification.
