Learn How to Mate in 2: Philidor Defense
This Philidor Defense puzzle is a classic middlegame tactical shot where active pieces punish an exposed king. White’s forces are coordinated around the enemy king, and the position is ripe for a forcing sequence that begins with check. The key idea is to use a queen sacrifice or queen invasion to drag the king into a vulnerable square, then finish with a knight move that creates a decisive fork mate. It’s a strong example of how piece activity can outweigh material.
