Pin Puzzle (Rated 1594): Win with a Pin — Exposed King Puzzle

This middlegame puzzle is a classic example of how an exposed king can turn a material deficit into a tactical win for the attacking side. The key idea is that a pinned queen and loose back-rank pieces create a forcing sequence where checks, forks, and discovered attacks work together. In classical chess, these patterns often appear when the king stays in the center and one active piece can dominate the board.
