Learn How to Spot Mate in 2: Kill Box Mate
This chess puzzle is a classic kill box mate pattern: the attacking side uses a forcing check to drive the enemy king onto a restricted square, then finishes with a rook sacrifice or capture that seals every escape route. The key idea is that the king’s own pieces and nearby defenders help create the box, so the final mating net is compact and unavoidable. In practical play, this often appears in the middlegame or endgame when rooks become active on open files and the king is exposed.
