Fork Advanced Puzzle (Rated 723): Fork — Win Material
A fork is a tactical move that attacks two or more valuable targets at once. In this chess endgame, Black’s active king exploits White’s poorly coordinated pieces, creating pressure against both the rook and bishop. The key idea is not a mating attack, but a decisive material gain caused by a double attack. When a queen supports the position from behind, even a centralized king can become a powerful tactical piece.
