Learn How to Fork: Decisive Material Gain
This middlegame puzzle comes from the Philidor Defense, where White’s active queen creates a tactical fork against the king and a loose rook. The key idea is that a forcing check can also improve the position by attacking multiple valuable targets at once. In classical chess, this kind of tactic often appears when one side has lead in development, a vulnerable king, and an undefended piece that can’t be easily protected.
