Learn How to Intermezzo: Decisive Material Gain
This puzzle is a classic intermezzo idea inside the Ruy Lopez Exchange Variation. White does not simply recapture or trade pieces in the most obvious way; instead, the position rewards a forcing tactical sequence that wins material by exploiting loose pieces and an exposed king. The key is to notice that Black’s coordination is fragile, so a forcing capture can create a check, remove a defender, and leave a major piece hanging.
