Learn How to Spot a Back Rank Mate: Mate in 3
This chess puzzle is a classic example of a back rank mate pattern in the middlegame, where the enemy king is boxed in by its own pawns and pieces. Even when one side is materially ahead, the game can end immediately if the king has no luft and the heavy pieces coordinate on the open file. The key idea is to use forcing checks to drag the king into a worse square, then exploit the overloaded defender and the pinned back-rank pieces.
