Learn How to Win with an Intermezzo: Tactical Refutation
This puzzle shows a classic intermezzo in the opening: instead of reacting passively to the opponent’s threat, White uses a forcing move that creates check and changes the order of events. The key idea is tactical refutation, where a seemingly active queen invasion is punished because the opponent’s queen becomes vulnerable and the position collapses tactically. In classical chess, these moments often decide the middlegame before development is complete.
