Learn How to Spot Back Rank Mate: Mate in 3
This middlegame puzzle shows how a king can be trapped by its own pieces and a weakened pawn shield. The key idea is a forcing queen sacrifice that drags the enemy king into a mating net, where every escape square is covered. Even though White is materially better, the position is decided by king safety rather than material count. In classical chess, these patterns often appear when heavy pieces coordinate on open files and the back rank becomes vulnerable.
