Learn How to Win Material: Discovered Attack
This middlegame puzzle shows a classic discovered attack idea: one piece moves with tempo, uncovering a stronger line of attack behind it. The position is especially sharp because the king is still in the center and both sides have active pieces aimed at loose targets. In classical chess, these tactical refutations often arise when a pinned or overloaded defender cannot meet every threat at once, leading to decisive material gain rather than a slow positional edge.
