Learn How to Win Material: Discovered Attack
This middlegame puzzle shows how a tactical shot can turn a stable-looking English Opening into a decisive material win. Black’s active pieces coordinate against White’s king and the e1-rook, creating a forcing sequence based on a discovered attack and a vulnerable back rank. The key idea is that one piece can be sacrificed or exchanged to open lines, expose the king, and remove the defender of a major piece. In sharp positions, activity can outweigh static material only if the follow-up is concrete.
