Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a queenside strike. One piece is pinned or overloaded, so a forcing capture creates check and exposes a second tactical target. The key idea is that the checking move is not just about forcing the king to react; it also opens the line for a stronger follow-up that wins material. In practical classical chess, these patterns often decide games because the defender cannot address both threats at once.
