Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a forcing check. One piece steps aside to open a line, exposing the enemy king and creating a direct tactical threat against the back rank and the queen’s defenses. The key idea is that the opponent’s pieces are overloaded: one defender is trying to cover multiple weaknesses at once, so a single forcing move can collapse the position and win major material.
