Learn How to Use an Intermezzo: Tactical Refutation
This puzzle shows a classic intermezzo: instead of recapturing immediately, the stronger side inserts a forcing tactical move that changes the evaluation at once. In the Queen's Gambit Declined, these moments often arise when a queen is overworked or a key piece is pinned to a valuable target. The idea is not flashy checkmate, but decisive material gain and a cleaner position. In classical chess, spotting the forcing move first is often the difference between advantage and disaster.
