Learn How to Win Material: Tactical Refutation
This puzzle comes from the Slav Defense and shows how a seemingly active piece can become a tactical liability. White has just created pressure with a knight on c7 and a bishop on f4, but Black can answer with a forcing check that changes the evaluation immediately. The key idea is to use activity, tempo, and king exposure to convert a middlegame imbalance into a winning material sequence. In classical chess, forcing moves often override static advantages.
