Learn How to Mate in 2: Back Rank Mate
This chess endgame puzzle shows how a rook can create a forced mating net when the enemy king is boxed in by its own pieces and pawns. The key idea is not material gain, but coordination: one rook gives a forcing check while the other delivers the final blow on the open file. In classical chess, these patterns often appear when the king has limited flight squares and the back rank is vulnerable.
