Learn How to Use an Intermezzo: Tactical Refutation
This puzzle shows a classic intermezzo idea in the Sicilian Defense, where a forcing check changes the move order before the opponent can recapture or consolidate. The key is that the position is already tactically loaded: the black queen is overextended, the king is still vulnerable, and a direct capture on the queen comes with tempo. In classical chess, these forcing sequences often decide middlegames by turning a threatened piece into a winning tactical refutation rather than a simple trade.
