Grand Prix Attack Puzzle (Rated 974): Win Material — Fork Tactic
This middlegame puzzle is a classic example of a tactical fork that wins material by forcing the king into a bad square and then picking up a loose piece. Black’s active knight jumps create immediate threats against the white king and the queen’s coordination, turning a balanced material count into a decisive advantage. The key idea is that a forcing check can be stronger than a direct capture when it exposes multiple weaknesses at once. Look for pieces that are overloaded, undefended, or trapped.
