Learn How to Kill Box Mate: Mate in 2
This puzzle is a classic kill box mate pattern: the attacking side uses a rook to force the enemy king into a cramped box, then finishes with a second rook delivering the final blow. The key idea is not material gain but coordination and restriction. Once the checking rook appears on the open file, the defending king has no useful escape squares and the response is forced. In chess endgame and classical chess positions like this, active rooks often decide everything.
