Learn How to Spot a Mate in 2: Greco's Mate
This puzzle is a classic mating net built around forcing checks and a rapid queen invasion. The key idea is to use a knight sacrifice to drag a defender away from the king’s shelter, then follow with a queen check that cannot be met by capture or escape. Patterns like this often appear in the middlegame when the king is exposed and the opponent’s pieces are overloaded or poorly coordinated.
