Learn How to Spot Mate in 1: Scandinavian Defense
This classical chess puzzle comes from the Scandinavian Defense and shows how a middlegame king can become helpless when the board is overloaded with threats. The key idea is that piece activity and king safety matter more than material when the enemy king has no safe squares. In positions like this, a single forcing move can end the game immediately because the defending pieces are too poorly placed to respond.
