Learn How to Spot Mate in 1: Queenside Attack
This middlegame puzzle comes from the Scotch Game and shows how a queenside attack can end the game instantly when the enemy king is boxed in. The key idea is that active pieces, open files, and a vulnerable back rank can combine into a forced mating net. Even when one side is materially ahead, a single tactical oversight can allow a direct finish. Always check for checks first, especially when the queen and rook coordinate on the same file or diagonal.
