Learn How to Spot Mate in 1: Rook Tactics
This puzzle is a classic middlegame mating pattern where a rook on an open file creates an immediate finish. The key idea is that the enemy king has limited escape squares, while a loose piece near the king makes the final blow possible. In positions like this, always scan for forcing moves first: checks, captures, and threats. When a rook can invade the back rank or a key file with tempo, a seemingly normal position can become a direct mate in 1.
