Learn How to Spot a Mate in 2: Back Rank Mate
This puzzle is a classic forcing finish built around king safety, piece coordination, and a vulnerable back rank. Even though the position is in the middlegame, the mating pattern feels like a chess endgame because there are few pieces left and every tempo matters. The key idea is to use a forcing check to drag the king into a worse square, then finish with a second decisive move that exploits the trapped king and the lack of escape squares.
