Learn How to Use an Intermezzo: Tactical Refutation
This puzzle comes from the Italian Game, Two Knights Defense, where tactics often decide the middlegame before the position simplifies. The key idea is an intermezzo: instead of reacting directly, Black inserts a forcing check that changes the move order and exposes White’s king. That tempo gain also keeps White’s bishop under pressure, turning a seemingly active piece into a tactical target and leading to decisive material gain.
