Fork Puzzle (Rated 1231): Win with a Fork — Endgame Tactics

This puzzle shows how a quiet-looking chess endgame can hide a forcing tactical shot. White’s queen activity is the key: it creates a direct check that also exposes a loose rook and an unsafe king. In classical chess, these moments often decide the game immediately because reduced material makes every tempo count. The idea is not just to check the king, but to use the check as a fork that wins a major piece and converts a winning advantage.
