Learn How to Spot a Mate in 2: Discovered Check

This Ruy Lopez middlegame puzzle shows how a discovered check can turn a strong piece into a mating net. White’s active knight and bishop coordination create immediate pressure around the black king, especially when the defender’s king shelter is weakened. The key idea is that one forcing move can open lines, expose the king, and make every escape square disappear. In tactical positions like this, material count matters less than king safety and piece activity.
