Learn How to Spot an Intermezzo: Tactical Refutation
This puzzle shows a classic middlegame intermezzo: instead of recapturing immediately, Black inserts a forcing check that changes the whole position. The key idea is tactical refutation through tempo, where a seemingly active white queen becomes vulnerable once the board is opened. In classical chess, these moments often decide the game because king safety, piece coordination, and material balance all interact at once. The position rewards calculation over general plans.
