Learn How to Win Material: Discovered Attack
This classical chess puzzle comes from the Italian Game and shows how a discovered attack can turn a middlegame into a decisive material win. White’s active pieces coordinate against the black king and the loose back-rank setup, creating a forcing tactical sequence. The key idea is that one checking move also opens a second threat on a major piece, so the defender is pulled in two directions at once. That combination of check and attack is what makes the tactic crushing.
