Learn How to Spot Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a forced mating pattern where the attacking side uses queen activity and king safety to end the game immediately. The key idea is that the defending king has no safe flight squares and the surrounding pieces cannot help in time. In positions like this, look for checks first, then ask whether the king can capture, block, or escape. When all three defenses fail, the mating net is complete.
