Learn How to Spot an Intermezzo: Tactical Refutation
This middlegame puzzle is a classic example of an intermezzo, where a forcing move changes the order of exchanges and wins material. Instead of recapturing immediately, the stronger side inserts a check that improves the position and exposes a loose piece. The key idea is tactical refutation: when a queen or knight is hanging, a forcing move can turn a seemingly active attack into a decisive material gain.
