Learn How to Use an Intermezzo: Decisive Material Gain
This middlegame puzzle comes from the Philidor Defense and shows how a forcing tactical idea can override static material concerns. White has an advanced pawn and active pieces, but the key is the exposed bishop and the vulnerable king zone. The winning idea uses a forcing check to disrupt coordination, then a follow-up capture that wins material. It is a classic example of a tactical refutation where activity and king safety matter more than the raw material count.
