Ruy Lopez Mate In 1 Beginner Puzzle (Rated 1012): Spot Mate in 1 — King Safety

This middlegame puzzle is a classic example of king safety deciding the game instantly. White’s pieces are already coordinated around the black king, and the key idea is that the enemy king has very few safe squares because its own pieces and pawns limit escape. In positions like this, the strongest move is often a forcing check that ends the game immediately. Training these patterns helps you recognize when a mating net is already in place.
