Learn How to Spot Mate in 1: Scandinavian Defense
This puzzle comes from the Scandinavian Defense and shows how a seemingly active middlegame can collapse instantly when the king is boxed in. The key idea is a direct mating net: the attacking side uses queen coordination and the enemy king’s limited escape squares to deliver a forced finish. Even with material on the board, king safety can outweigh everything else when the back rank and nearby files are under control.
