Learn How to Spot Mate in 2: Back Rank Mate
This chess endgame puzzle is a classic forcing sequence where the attacking side uses a queen sacrifice to drag the enemy king into a mating net. The key idea is not material, but coordination: one piece gives check, the king is forced to a specific square, and a rook then delivers the final blow on the open file. In classical chess, these patterns often appear when the king has limited escape squares and the back rank is vulnerable.
