Learn How to Back Rank Mate: One-Move Finish
This puzzle is a classic back rank mate pattern in a middlegame setting. The key idea is that the enemy king has very limited escape squares because its own pawns and pieces restrict flight, while a rook on an open file can deliver the final blow. Even though material may look imbalanced, tactical factors matter more than the static count when the king is boxed in and a major piece is hanging.
