Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack where one piece is sacrificed or moved to open a stronger line for another attacker. The key idea is that the king’s shelter is already weakened, so a forcing move can expose the defender and create a direct tactical refutation. In positions like this, active pieces and king safety matter more than raw material, especially when a queen and bishop coordinate against the enemy king.
