Bowdler Attack Puzzle (Rated 979): Fork — Win Material

A fork is a tactical move that attacks two or more targets at once, often combining a check with an attack on a valuable piece. In this middlegame position, Black uses an active knight jump to exploit White’s weakened king zone and overloaded defenders. The key idea is that a forcing check changes the opponent’s priorities, creating a second threat that cannot be handled cleanly. Although White has extra material, Black’s coordination and piece activity produce a decisive material gain.
