Learn How to Use a Discovered Attack: Tactical Refutation
This middlegame puzzle is a classic example of a discovered attack, where one piece’s move opens a line for another to strike with tempo. The key idea is that the apparent threat is only the trigger; once the line is opened, the opponent’s king becomes vulnerable and a major piece can be won. In classical chess, these tactical refutations often appear when active pieces coordinate against an exposed king and loose defenders.
