Learn How to Intermezzo: Crushing Tactical Refutation
This puzzle shows a classic middlegame intermezzo, where a forcing tactical move changes the order of operations and wins material. The key idea is that the opponent’s queen is exposed on the same diagonal as a vulnerable piece, so a check can be used to create a tempo before recapturing the queen. In practical classical chess, these tactical refutations often appear when the king is still in the center and piece coordination is loose.
