Sacrifice Puzzle (Rated 1375): Spot Back Rank Mate — Mate in 3

This puzzle is a classic back rank mate pattern hidden inside a sharp middlegame. White’s heavy pieces coordinate to attack the enemy king, which is stuck with limited escape squares and vulnerable back-rank coverage. The key idea is that a forcing queen move can create a direct checking net while also luring a defender away from the critical file. In practical classical chess, these motifs often appear when king safety matters more than material.
