Learn How to Fork: Tactical Refutation
This middlegame puzzle is built around a tactical refutation where one active queen move creates a forcing sequence and wins material. The key idea is a fork: a single piece attack that hits multiple targets at once, often with check included to limit the opponent’s replies. Here, king safety is the dominant factor, so the attack works because the defender’s pieces are poorly coordinated and a loose piece can be picked up while the king is forced into passivity.
