Learn How to Spot Intermezzo: Decisive Material Gain

This puzzle comes from a Queen's Pawn Game structure where the key idea is an intermezzo: a forcing move that changes the order of captures and creates a decisive material gain. In practical classical chess, these tactics often appear when a queen, bishop, or knight is left loose and the opponent can exploit a check or a pin before recapturing. The position rewards calculation, not long-term strategy, because the tactic immediately shifts the evaluation in Black's favor.
