Queen's Gambit Declined Rook Fork Chess Puzzles

The Queen's Gambit Declined Rook Fork is a tactical motif that appears in Queen's Gambit Declined structures when a rook can attack two valuable targets at once, usually the king and queen, or the king and a loose piece. It often arises after the central tension from moves like ...e6 and ...d5 has settled and one side's back rank or 7th-rank pieces become vulnerable. For an intermediate player, the key feature is a rook landing on a checking square that simultaneously creates a fork.
