Learn How to Use an Intermezzo: Decisive Material Gain
This puzzle comes from the Ponziani Opening and shows a classic tactical refutation based on an intermezzo. Black uses a forcing check to exploit loose white pieces and turn a tactical sequence into decisive material gain. The key idea is that the position is not about slow development anymore: it is about immediate calculation, king safety, and punishing hanging pieces before they can coordinate. In classical chess, these moments often decide the game on the spot.
