Learn How to Spot: Back Rank Mate
This puzzle is a classic example of a back rank mate pattern in a sharp middlegame-to-endgame setting. The key idea is that the enemy king has very limited escape squares because its own pawns and pieces restrict movement. When the defending side is boxed in like this, a single forcing move can end the game immediately. Recognizing the king’s lack of luft and the alignment of heavy pieces is often enough to find the winning tactic.
