Learn How to Win Material: Discovered Attack
This Vienna Game middlegame puzzle is a classic example of a discovered attack that wins material by forcing the king to react to a direct threat. White’s active pieces are aimed at the black king, while Black’s queen and minor pieces are overloaded by tactical pressure. The key idea is that one forcing move opens a line, creates a check, and simultaneously exposes a vulnerable target in the center. In classical chess, these tactical shots often decide the game immediately.
