Learn How to Back Rank Mate: Mate in 3
This middlegame puzzle is a classic example of king safety collapsing into a forced mating net. The key idea is that the defending king has limited escape squares, while heavy pieces coordinate to exploit the back rank and nearby weak squares. Even when material is close to equal, active pieces and an exposed king can decide the game immediately. In practical classical chess, these patterns often appear after a quiet-looking position suddenly turns tactical.
