Learn How to Win Material: Philidor Defense
This puzzle is a classic middlegame kingside attack where king safety outweighs material. White’s pieces look active, but the king is exposed and the defensive pieces are overloaded. When the enemy king is stuck in the center or short on shelter, forcing moves often become decisive. The key idea is to use checks and threats to drag the king into a worse square, then remove the defender of the final mating net.
