Fork Puzzle (Rated 1290): Win with a Fork — Chess Endgame Puzzle

This chess endgame puzzle shows how a single tactical idea can decide a seemingly calm position. The key is a fork: one piece creates a direct check while also attacking an important target, forcing the opponent into a narrow defensive path. In practical classical chess, these moments often appear when active pieces and passed pawns combine to overload the enemy king and rook. The side with the more active knight can turn a small advantage into a winning material gain.
