Sacrifice Puzzle (Rated 1407): Deflect — Mate in 3

This puzzle is a classic mate in 3 built around deflection and a forcing sacrifice. The key idea is to drag a key defender away from its post so the remaining pieces can invade the king’s shelter. Even though the position looks like a normal middlegame, the tactical pattern is much more important than material. Once the defender is pulled off the critical square, the attack becomes a direct mating net with no useful escape squares.
