Learn How to Spot a Mate in 4: Queen Sacrifice
This middlegame puzzle is a classic example of a forcing mating net built around king safety, pins, and a queen sacrifice. White’s pieces are already coordinated against the exposed king, and the key idea is to remove the main defender while keeping the enemy king boxed in. Once the first forcing move lands, every reply is constrained by checks, discovered threats, and the geometry of the back rank. It is a strong lesson in how tactical pressure can outweigh material.
