Learn How to Spot Mate in 1: Sicilian Defense
This middlegame puzzle comes from the Old Sicilian and shows how quickly an exposed king can be punished when the queen and enemy king line up on the same diagonal or file.

The key lesson is to always scan for forcing checks before considering material grabs, especially when the opponent’s king is still in the center and your queen has access to the king zone.
