French Defense Deflection Puzzle (Rated 1139): Deflect — Mate in 2

This middlegame puzzle is a classic example of a kingside attack where the defender is overloaded and the king’s shelter is fragile. White’s active rook and bishop coordination create a forcing tactical sequence that uses deflection to pull a key defender away from the back rank. Once that defender is removed from its post, the remaining line to the king opens immediately, turning a material imbalance into a direct mating net.
