Learn How to Spot Intermezzo: Tactical Refutation
This puzzle shows a classic intermezzo idea in the Queen's Gambit Declined: instead of recapturing immediately, Black inserts a forcing check that changes the evaluation at once. The key is that White’s queen is active but vulnerable, and the position contains tactical tension around the king, pinned pieces, and loose material. In classical chess, these moments often decide the middlegame because a single forcing move can win the queen or leave the opponent with no good reply.
