Learn How to Spot Smothered Mate: Ruy Lopez Puzzle
This puzzle comes from the Ruy Lopez Berlin Defense and shows how a seemingly active position can hide a forced mating net. The key idea is smothered mate: the king is boxed in by its own pieces and has no flight squares, so a single tactical blow ends the game immediately. Even in a middlegame with material imbalance, king safety can outweigh everything else when the defender’s pieces block escape and key squares are overloaded.
