Hanging Piece Puzzle (Rated 1078): Spot Mate in 1 — French Defense Exchange

This puzzle is a classic middlegame tactical finish from the French Defense Exchange Variation, where material balance and king safety are completely out of sync. White’s queen and pieces look active, but the position contains a hidden tactical weakness around the king’s back rank and the open e-file. In classical chess, these positions reward forcing moves that exploit hanging pieces, pins, and overloaded defenders before the opponent can respond.
