Learn How to Back Rank Mate: Rook Tactics
This middlegame puzzle is a classic back rank mate pattern. The key idea is that the enemy king has too little room to escape because its own pieces and pawns block the flight squares. When a rook can invade the back rank with support from active pieces, the position can end immediately. Even in a materially imbalanced game, king safety can outweigh everything else when the defender is boxed in and the final rank is vulnerable.
