Mate Threat Puzzle (Rated 600): Exploit Back Rank Mate — Chess Puzzle with Theory & Hints

This middlegame puzzle is built around king safety and a loose piece on the e5 square. Black’s queen activity creates a tactical shot that wins material by exploiting a skewer-like alignment and the exposed white king’s position. Even though White has active rooks and a passed pawn, the tactical reality is more urgent: the queen can capture on e5 and leave White’s coordination in trouble. It is a classic example of how one forcing move can outweigh long-term advantages.
