Pin Puzzle (Rated 1595): Win with a Pin — Endgame Masterclass

This chess endgame shows how a pin can become more than a tactical detail: it can decide the whole game. When a rook or other key defender is pinned to the king, the defender loses freedom, and the attacker can force simplification on favorable terms. In classical chess, these positions often look quiet, but the strongest move is usually the one that increases pressure on the king and removes the main defender at the same time.
