Learn How to Spot Mate in 1: Queen Sacrifice
This Vienna Game middlegame puzzle is a classic example of a mating net built around king safety. White’s pieces are coordinated to exploit the exposed black king, and the key idea is to recognize when the opponent’s king has no safe squares, no useful interpositions, and no way to capture the attacking piece. In positions like this, a queen sacrifice can be the cleanest finish because the attack is already overwhelming and the final move is forced.
