Learn How to Spot Mate in 1: Back Rank Mate
This puzzle is a classic mating pattern where the attacking side uses active piece placement to finish the game immediately. The key idea is that the enemy king has limited escape squares, and a well-placed queen can exploit the cramped back rank. Even though the position is not about long-term endgame technique, it still rewards endgame awareness: when the king is boxed in and the pieces are passive, tactical finishes often appear at once.
