Learn How to Mate in 3: Queen Trap
This middlegame puzzle is a classic example of forcing play: the attack begins with a checking move that drags the enemy king into a narrow defensive path. The key idea is not raw material, but coordination. White’s queen and rook work together to create a mating net, while the black queen becomes overloaded and unable to defend everything at once. Patterns like pin, skewer, and removal of the defender are all present in the background.
