Learn How to Mate in 2: Back Rank Mate
This chess endgame puzzle is a classic example of a forcing back rank mate. The key idea is to use a rook sacrifice or clearance move to drag the defending king onto a vulnerable square, where the second rook can deliver the final checkmate. Even though the material balance is unfavorable, tactical coordination and king restriction matter more than raw material. In classical chess, these patterns often appear when the enemy king has limited flight squares and its own pieces block escape routes.
