Learn How to Spot: Mate in 1
This puzzle comes from the Vienna Game and shows a classic middlegame mating pattern where the enemy king has too few safe squares and the queen can deliver a direct finish. The key idea is to recognize when king safety matters more than material. Even in a position where White is clearly better, the real win is tactical: a single forcing move ends the game immediately because the king is exposed and the defensive pieces are overloaded.
