Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Indian Defense and shows how a discovered attack can turn a strong-looking position into a winning tactical sequence. White’s pieces are active, but the key idea is that one forcing check can expose loose coordination and create a direct threat against the queen and bishop. The position rewards calculation, because the best continuation is not a quiet improving move but a forcing tactical refutation that wins material and leaves Black with the better game.
