Fork Advanced Puzzle (Rated 698): Fork — Win Material

A fork is a tactical attack in which one piece creates simultaneous threats against two or more targets. In this middlegame position, Black’s queen can exploit the alignment of the white king and rook, turning active piece placement into a decisive material gain. The key idea is to value forcing moves first: checks restrict the opponent’s replies while increasing the chance of attacking an additional valuable piece. Even when one side is materially behind, tactical coordination can outweigh static advantages.
