Learn How to Spot a Zwischenzug: Tactical Refutation
This puzzle shows a classic middlegame tactical refutation in the Queen's Gambit Declined. The key idea is an intermezzo, or zwischenzug, where the side to move uses a forcing capture to change the order of events and win material. Instead of reacting passively, Black exploits a tactical motif against the white queen and the loose pieces around it. The position is a good example of how one active move can turn a slightly better position into a decisive material gain.
