Learn How to Use an Intermezzo: Winning Material
This puzzle shows a classic intermezzo idea in the Queen's Pawn Game, where a forcing check changes the move order and wins material. Instead of recapturing immediately, Black uses a tactical in-between move to exploit the exposed white king and the loose queen on d4. The position is a good example of how opening play can turn into a decisive tactical refutation when development is incomplete and king safety is compromised.
