Learn How to Mate in 2: Queen and Knight
This middlegame puzzle is a classic example of forcing play: the attacking side uses a queen and knight to create an immediate mating net. The key idea is that the enemy king has limited flight squares, while one well-placed checking move can drag it onto a vulnerable square. In positions like this, material count matters less than king safety, piece coordination, and the ability to force responses. The attack works because the defender’s pieces are overloaded and the king is exposed.
