Learn How to Killbox Mate: Mate in 2
This puzzle is a classic killbox mate pattern in a sharp middlegame-to-endgame setting. The key idea is to use the open file and the exposed king to force a sequence of checks that leaves the defender with no useful squares. Even though material is roughly balanced on the board, king safety is the deciding factor. In classical chess, these short tactical finishes often come from active rooks coordinating against a weakened king zone.
