Philidor Defense Exchange Variation Beginner Puzzle (Rated 1057): Exploit a Discovered Attack — Decisive Material Gain

This middlegame puzzle comes from the Philidor Defense and shows how a discovered attack can decide the game by winning major material. White’s pieces are lined up so that one move creates a direct tactical threat against the enemy queen while also forcing the king to respond. The key idea is that a seemingly quiet bishop move opens a hidden line, turning piece activity into a concrete gain. In classical chess, these tactical shots often outweigh static material deficits.
