Learn How to Spot Mate in 1: Queen Sac
This middlegame puzzle is a classic king-safety lesson: one side’s pieces are coordinated around the enemy king, and a single forcing move ends the game immediately. The key idea is that the queen can deliver checkmate by landing on a square where it cannot be captured, blocked, or escaped from. In positions like this, material count matters far less than the vulnerability of the king and the control of nearby escape squares.
