Back Rank Mate In 2 Puzzle: Back Rank Mate — Deflection
A back rank mate often begins when the defending king has little room because its own pieces or pawns block escape squares. In this position, White’s rook can invade the open d-file with check, forcing Black’s bishop to act as the only practical defender. That bishop is overloaded: it must address the checking rook, yet moving it allows White’s queen to enter with decisive force. The pattern combines deflection, a pin, and coordinated rook-and-queen pressure.
