Learn How to Spot Back Rank Mate: Mate in 4
This puzzle is a classic middlegame tactical finish built around king safety and a back rank mating net. White’s active pieces coordinate to overload the defender, exploit pinned pieces, and force the black king into a narrow escape route. The key idea is not raw material, but timing: once the defender is distracted, the attack becomes a forcing sequence of checks and captures that leaves the king with no safe squares. Patterns like discovered check, skewer, and removal of the defender are central here.
