Learn How to Force Mate in 3: Back Rank Mate
This chess endgame shows how a seemingly active defense can collapse when the king has no luft and the back rank is overloaded. White’s pieces work together to create a forcing sequence based on check, deflection, and a final rook invasion. The key idea is that the defender’s king and rook are tied to one another, so one tactical shot can remove the last shield. In classical chess, these mating nets often appear when heavy pieces are already aligned on open files.
