Learn How to Use an Intermezzo: Winning Material
This middlegame puzzle is a classic example of using an intermezzo to turn pressure into a decisive material gain. White’s pieces look active and the position seems balanced by activity, but Black has a forcing tactical resource that exploits the pinned bishop and the exposed king. The key idea is that a checking move can interrupt the natural recapture sequence, creating a stronger follow-up and winning material cleanly.
