Learn How to Use an Intermezzo: Tactical Refutation
This puzzle shows a classic intermezzo idea in the Catalan Opening: instead of recapturing or retreating immediately, White uses a forcing check to expose the opponent’s king and queen coordination. The key point is that the position is tactically overloaded, with Black’s queen on d4 creating pressure but also becoming vulnerable to a direct refutation. In practical classical chess, these moments often decide the game because one forcing move can turn a messy middlegame into a winning material sequence.
