Fork Puzzle (Rated 816): Win With a Fork — Endgame Tactics

This chess endgame puzzle shows how a single tactical idea can outweigh material and activity. Even in classical chess, the side with the extra rook or better structure can lose if the king becomes vulnerable to a fork. The key is to notice when an enemy piece can attack two valuable targets at once, especially when one target is the king. In simplified positions, forcing moves often decide everything because there are fewer defensive resources left.
