Learn How to Spot Mate in 1: King Safety
This puzzle is a classic mate in 1 based on king safety and a tight mating net. Even in a material-heavy classical chess position, the side to move can finish the game immediately because the enemy king has very few escape squares and its own pawns block the flight route. The key idea is to look for direct checks first, then ask whether the king can capture, block, or run. When all three fail, the attack is over.
