Learn How to Spot Mate in 4: Queen Sacrifice
This middlegame puzzle is a classic example of forcing play against a weakened king. White’s queen and rooks coordinate to exploit the exposed king zone, where checks become more important than material. The key idea is a queen sacrifice that drags a defender away and opens the line for a rook invasion. Once the king is forced into a cramped defensive setup, the attack becomes a direct mating net rather than a simple material win.
