Queens Gambit Declined Intermezzo Beginner Puzzle (Rated 1020): Win with an Intermezzo — Crushing Tactical Refutation

This middlegame puzzle shows a classic intermezzo idea in the Queen's Gambit Declined: instead of recapturing immediately, the stronger side inserts a forcing check that changes the evaluation. The key is that the opponent’s queen and rook coordination is loose, while the king is exposed to tactical pressure. Once the forcing move lands, White’s active queen becomes vulnerable and the position collapses into a winning material sequence.
