Learn How to Back Rank Mate: King Safety
This middlegame puzzle is a classic king-safety lesson: one side’s king is boxed in, the escape squares are restricted, and the heavy pieces can coordinate to deliver a forcing finish. The key idea is that a seemingly active piece can also be a tactical decoy, pulling the king into a worse square while the remaining rook or bishop completes the mating net. In classical chess, these patterns often appear when the back rank is weak and the defender has no time to create luft.
