Learn How to Spot Mate in 2: Mating Net
This middlegame puzzle is a classic mating net: the attacking queen coordinates with nearby pieces to trap the king and remove escape squares.

In positions like this, king safety matters more than the static evaluation, and a seemingly active queen can become overloaded when it must defend too many threats at once.
