Learn How to Crush with a Discovered Attack: Philidor Defense

This puzzle shows a classic middlegame tactical refutation in the Philidor Defense. White’s queen has overextended, and Black can exploit the exposed king by using a bishop sacrifice to open lines and force a king capture. The key idea is that a piece can be offered to remove a defender and create a discovered attack on the queen, turning a seemingly active white position into a decisive material win. It is a sharp example of kingside attack and tactical punishment.
