Learn How to Kill Box Mate: Mate in 2
This middlegame puzzle shows a classic kill box mate pattern: the enemy king is boxed in by its own pieces and the checking side uses a forcing rook sacrifice to seal the escape squares. The position is a strong example of king safety overriding material, since White is already ahead but must still find the only forcing sequence. In classical chess, these motifs often appear when open files and active rooks combine against a cramped king.
