Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Alekhine Defense and shows how a tactical idea can outweigh static material. White’s queen is active, but Black has a powerful forcing sequence based on a discovered attack and a skewer against the queen. The key lesson is that active pieces and king safety can turn a seemingly worse material balance into a winning combination. In classical chess, tactics often decide whether an advantage is real or only temporary.
