Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Ruy Lopez Cozio Defense and shows how a single tactical shot can overturn a large static material edge. White may look better on paper, but the king position and piece coordination are fragile. Black’s active pieces create a forcing sequence that uses check, fork ideas, and a follow-up capture to win material. In practical classical chess, these tactical refutations often matter more than the raw count of pawns and pieces.
