Ruy Lopez Morphy Defense Back Rank Mate Puzzle (Rated 955): Spot Back Rank Mate — Ruy Lopez Tactic

This middlegame puzzle comes from the Ruy Lopez and shows how king safety can outweigh material. Black’s pieces are coordinated around the white king, and the key idea is a forcing queen sacrifice that drags the king into a mating net. The position highlights classic tactical motifs: back rank mate, discovered attack, pin, and skewer. Even when White is materially ahead, an exposed king and loose back-rank coordination can decide the game immediately.
