Learn How to Use an Intermezzo: Decisive Material Gain
This middlegame puzzle is a classic example of an intermezzo, also called a zwischenzug, where the strongest move is not the obvious recapture. Instead of immediately resolving the tension, White uses a forcing check to improve the position and expose the enemy queen and king at the same time. The key idea is tactical refutation: when a piece is overloaded or poorly placed, a forcing move can turn a normal-looking position into a winning material sequence.
