Learn How to Win Material: Discovered Attack
This puzzle is a classic discovered attack pattern in a sharp middlegame. White can use a forcing capture to expose the enemy king and open a line for the rook, turning a defended-looking position into a decisive material win. The key idea is that one piece is doing two jobs at once: it gives check while also removing a defender and creating a direct attack on a valuable target. These tactical motifs often decide classical chess games when the king is slightly exposed.
