Learn How to Spot Mate in 1: Kill Box Mate
This middlegame puzzle is a classic example of a mating net where king safety matters more than material. White’s pieces coordinate to restrict the enemy king’s escape squares, and the key idea is that a seemingly active defending piece can actually be overloaded or pinned. In positions like this, always ask whether the king has any legal flight squares, whether a rook or queen can deliver a forcing check, and whether the defender is tied to another duty. The tactical finish is immediate once the king is boxed in.
