Learn How to Spot Back Rank Mate: Mate in 3
This Ruy Lopez Exchange Variation puzzle shows how a seemingly active middlegame can hide a forced mating net. White’s king safety is the key imbalance: the king is boxed in, the f-pawn shield is weakened, and the heavy pieces are lined up to exploit the back rank. The winning idea is a forcing queen sacrifice that drags the king into a mating corridor, where rook coordination finishes the attack. It is a classic example of a tactical attack overriding material count.
