Fork Puzzle (Rated 1110): Win with a Fork — Chess Endgame Puzzle

This puzzle shows how a small tactical shot can decide a seemingly balanced chess endgame or middlegame. White’s queen activity is the key: the enemy king is slightly exposed, and a loose rook on the edge can be targeted at the same time. In classical chess, these positions reward active pieces and accurate calculation over material count. The winning idea is a forcing move that creates a fork, checks the king, and wins a major piece.
