Learn How to Win Material: Tactical Refutation
This Ruy Lopez classical variation puzzle is a great example of a tactical refutation in the middlegame. Black’s counterplay works because White’s advanced pieces and central knight create targets, while a pinned pawn and loose coordination make the position tactically vulnerable. The key idea is to notice when a seemingly active setup is actually overextended, allowing Black to win material by exploiting a fork and a pin at the same time.
