Learn How to Spot Killbox Mate: Mated in 7
This puzzle is a classic mating attack built around an exposed king and a tightly controlled escape zone. Even though material may look balanced or even favorable for one side, the real story is king safety: the defending king has too few squares, and every forcing move narrows the box further. In chess endgame and classical chess studies alike, these patterns often come from checks, rook activity, and queen coordination rather than direct material wins.
