Botez Gambit Puzzle (Rated 914): Spot Mate in 3 — Back Rank Mate

This middlegame puzzle is a classic king-safety finish: the attacking side uses a forcing queen sacrifice to drag the enemy king into a mating net. The key idea is that the defender’s pieces and pawns leave the back rank vulnerable, so checks become decisive when every escape square is covered. Even though material is down, active pieces and coordination matter more than count when the king is boxed in.
