Learn How to Spot a Mate in 3: Queen Trap
This middlegame puzzle is a classic forcing sequence built around king safety and a vulnerable back rank. White’s material edge looks comfortable, but the exposed king and loose coordination create a tactical window for Black. The key idea is to use a forcing queen check that drags the king into a mating net. Once the king is forced to step aside, the follow-up checks become unavoidable and the final position is a clean checkmate.
