Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a forcing fork. White’s active pieces coordinate against an exposed black king and loose back-rank defenders, creating a tactical sequence that wins material. The key idea is that one piece steps aside to reveal a stronger line of attack, while another piece jumps in with check and a fork. In practical classical chess, these patterns often decide long middlegame battles before any endgame is reached.
