Fork Puzzle (Rated 1123): Win with a Fork — Chess Endgame Puzzle
This chess endgame is a great example of how a tactical shot can decide a seemingly quiet position. White’s rook activity is the key: the rook can invade, attack multiple targets at once, and force the defender into a passive reply. In endgames, forks are especially powerful because pieces are fewer and king activity matters more. Even when down material, active coordination can turn the position into a winning advantage.
