Learn How to Win the Pin: Decisive Material Gain
This middlegame puzzle is built around a powerful pin on the queen that turns a tactical idea into a winning material sequence. The key is that one piece becomes overloaded: it must protect the king’s safety and also defend a valuable piece. When the pinned piece is forced to capture, the follow-up wins the queen’s support structure and leaves the opponent with no good recapture. These are classic classical chess themes: pin, removal of the defender, and a forcing exchange that decides the position.
