Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic tactical refutation where one active queen move exposes loose pieces and wins decisive material. The key idea is to notice when an enemy queen, rook, or knight is overworked and when a capture can create a forcing sequence. Here, the position rewards calculation over general strategy: the best continuation uses a forcing capture, then a recapture, and finally a rook check that takes advantage of the open file and the exposed king.
