Learn How to Exploit a Discovered Attack: Tactical Refutation
This middlegame puzzle comes from the Queen's Pawn Game, Colle System, where one tactical shot turns a stable-looking position into a decisive material win.

In positions like this, the opponent’s king safety and piece coordination matter more than simple material count, especially when a pinned defender can’t respond normally.
