Mate In 2 Puzzle (Rated 750): Spot Back Rank Mate — Mate in 2

This puzzle is a classic back rank mate pattern in a middlegame setting. White’s heavy pieces coordinate to exploit a cramped king and a vulnerable first rank, where the defender’s own pieces and pawns block escape squares. The key idea is not raw material, but forcing the enemy king into a box where every flight square is covered. In classical chess, these motifs often appear after a forcing check that drags a defender away from the critical square.
