Learn How to Use an Intermezzo: Decisive Material Gain
This middlegame puzzle shows a classic intermezzo idea: instead of recapturing or retreating immediately, White inserts a forcing check that changes the whole tactical picture. The position is rich in hanging pieces, pins, and overloaded defenders, so the first forcing move wins time and exposes Black’s coordination. In practical classical chess, these tactical shots often decide the game by turning a material deficit into a winning attack or a clean material gain.
