Learn How to Trap a Piece: Philidor Defense Tactic
This Philidor Defense puzzle shows a classic opening trap where a seemingly active piece becomes overloaded and vulnerable to tactical refutation. The position is a middlegame, but the idea is very much about opening theory: one side has overextended the queen and created a target that can be attacked by a lower-value piece. The key lesson is that forcing moves can turn a normal-looking development sequence into decisive material gain by exposing a hanging piece and limiting counterplay.
