Fork Puzzle (Rated 983): Win Material — Fork
This chess endgame demonstrates how a well-placed knight can create a powerful fork against two valuable pieces. The key idea is to recognize when an attacked piece is not the only problem: a forcing knight jump may attack a rook and bishop at once, producing a direct material gain. Such tactics often arise when pieces are active but insufficiently defended. In endgames, winning even a small amount of material can be decisive because there are fewer pieces available to create counterplay.
