Learn How to Win Material: Tactical Refutation
This puzzle comes from the Ruy Lopez, Cozio Defense and shows how a long opening can suddenly turn into a tactical refutation. White’s active knight and pressure around the black king create a forcing sequence that punishes loose pieces and an exposed king. The key idea is not a flashy mate, but decisive material gain through forcing captures and checks. In classical chess, these moments often decide the game before the endgame ever begins.
