French Defense Steiner Variation Mate In 1 Beginner Puzzle (Rated 1078): Spot Mate in 1 — Queen Trap
This middlegame puzzle is a classic example of a forced mating net built around king safety. White’s pieces are already aimed at the enemy king, and the position contains several tactical clues: exposed king cover, overloaded defenders, and a vulnerable back rank around the black monarch. In positions like this, the strongest move is often a direct check that ends the game immediately rather than winning material. The key is to look for the move that removes every escape square at once.
