Learn How to Use an Intermezzo: Crushing Tactical Shot
This puzzle shows a classic intermezzo idea: instead of recapturing or defending in the obvious way, Black inserts a forcing check that changes the whole position. The key is that the king is dragged into a vulnerable square, and only then can the follow-up tactic work. In practical chess, these moments often arise in the middlegame when king safety matters more than material count and one active piece can decide everything.
