Learn How to Use an Intermezzo: Tactical Refutation

This puzzle shows a classic middlegame intermezzo: instead of recapturing immediately, the stronger side inserts a forcing check that changes the move order and wins material. The key idea is tactical refutation, where a seemingly active queen move is punished because the opponent’s pieces are loose and the king is still in the center. In classical chess, these moments often decide the game by turning activity into a decisive material gain.
