Pin Puzzle (Rated 1684): Win with a Long Pin — Endgame Tactics

This chess endgame shows how a long pin can turn a seemingly active enemy piece into a tactical liability. When a piece is tied to the king or a more valuable target, even a small forcing move can create a decisive sequence. Here, the key idea is not just winning material, but using pressure on the king zone to overload defenders and expose a hidden tactic. In classical chess, these motifs often decide simplified positions.
