Learn How to Exploit a Discovered Attack: Tactical Gain
This middlegame puzzle from the Vienna Game shows how a discovered attack can turn an active position into a decisive tactical gain. White’s pieces are already aimed at the black king, but Black’s trigger move creates a new line of force that exposes a key defender. The idea is to use a forcing sequence that wins material by attacking along a file while the opponent’s pieces are overloaded and pinned. It is a classic example of tactical coordination over raw material.
