Learn How to Spot Opera Mate: Mate in 3
This puzzle is a classic opera mate-style finish where the attacking side uses forcing checks to drive the enemy king into a boxed-in position. Even though the material balance is heavily against White, the active rook and bishop create a mating net through the back rank and the open f-file. The key idea is an x-ray attack: one piece attacks through another, so the defender’s pieces become overloaded and unable to stop the final mating sequence.
