Learn How to Win Material: Discovered Attack
This middlegame puzzle shows how a forcing check can create a discovered attack and win major material. White’s active pieces are aimed at the black king, while Black’s back rank and loose queen-side pieces are under pressure. The key idea is that one tactical move can do two jobs at once: check the king and uncover a second threat against a valuable target. In classical chess, these double-purpose moves often decide the game immediately.
