Learn How to Win Material: Discovered Attack
This puzzle comes from the Four Knights Game and shows a classic tactical refutation in the middlegame. White’s pieces look active, but the king is still in the center and one key bishop is overextended. Black can use a forcing tactical sequence to exploit the pinned and overloaded pieces, turning a quiet-looking position into a decisive material win. The idea is not a mating attack, but a clean winning combination based on discovered attack and removal of a defender.
