Fork Puzzle (Rated 865): Win with a Fork — Chess Endgame Puzzle

This chess endgame puzzle is a classic example of how a single tactical motif can outweigh material. White’s active rook and knight coordinate to create a forcing sequence that wins a key defender and leaves Black’s heavy piece trapped. In practical classical chess, these positions reward accurate calculation over greed: the side with better piece activity can often turn a material deficit into a decisive advantage through a fork, check, and simplification.
