Learn How to Use an Intermezzo: Tactical Refutation
This middlegame puzzle is a classic example of an intermezzo, where the best reply is not the most obvious capture but a forcing tactical move that changes the evaluation immediately. The key idea is that one side has a hanging piece and an undefended target, so a direct material win becomes possible by first creating a stronger threat. In practical classical chess, these moments often decide the game because a single tempo can turn a small edge into a decisive advantage.
