Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack: one piece moves with tempo, uncovering a stronger line for another piece behind it. The position also features a pinned piece and an exposed enemy king, so the tactical idea is not just to attack a rook, but to do so with check and gain. In practical chess, these motifs often decide games because the opponent cannot respond to every threat at once.
