Learn How to Mate in 2: Back Rank Mate
This puzzle is a classic forcing finish in the chess endgame, where active pieces outweigh raw material. White’s queen and rook coordinate to create a mating net around the enemy king, and the key idea is to use a forcing check that drags the king into a worse square. In positions like this, king safety matters more than material, and a single tactical shot can end the game immediately. It’s a great example of how classical chess tactics punish loose back-rank and king-side weaknesses.
