Fork Puzzle (Rated 1247): Win with a Long Fork — Chess Endgame Puzzle

This chess endgame puzzle is all about a long knight fork that wins material by forcing the king into a bad square. In simplified positions, active pieces matter more than pawn count, and a single check can completely change the evaluation. Here, the attacking side uses tempo-gaining checks to drive the king away from safety, then lands on a powerful outpost that attacks multiple targets at once. It is a classic example of how classical chess endgame technique can turn a slight edge into a decisive one.
