Learn How to Spot an Intermezzo: Tactical Refutation
This puzzle is a classic intermezzo idea in the middlegame: instead of recapturing immediately, White inserts a forcing move that changes the tactical picture. The key is that the opponent’s last move created a loose piece and a vulnerable back rank/king coordination issue, so a direct exchange sequence becomes stronger than it first appears. In practical terms, White uses a forcing queen move to win material and expose the opponent’s pieces to a clean tactical refutation.
