Fork Advanced Puzzle (Rated 1474): Fork — Win Material

A fork is a tactical move that attacks two or more valuable targets at once, often involving a king, rook, queen, or another minor piece. In this chess endgame, Black must recognize that active white pieces create immediate tactical pressure around the king and rook. The best defensive idea uses a knight to create a double attack while also challenging White’s coordination. This is a useful example of how tactical awareness can outweigh material advantages and turn a difficult position into a manageable one.
