Learn How to Use an Intermezzo: Tactical Refutation
This puzzle shows a classic middlegame intermezzo: instead of recapturing immediately, the stronger side uses a forcing tactical move to change the order of events. The key idea is that the opponent’s queen is exposed and the king is still vulnerable, so a direct check can create a decisive material gain. In classical chess, these forcing sequences often decide the game before the position can simplify into a chess endgame.
