Queen's Gambit Declined Puzzle (Rated 993): Win Material — Fork Tactic

This chess endgame puzzle shows how a single forcing move can transform an equal-looking position into a winning material advantage. The key idea is a rook-based fork that attacks the enemy king and a valuable piece at the same time, creating immediate pressure and forcing a response. In classical chess, these tactical shots often appear when the king is active but exposed, and when pieces are lined up on open files or weak squares. The result is a clean conversion of activity into material gain.
