Learn How to Spot a Mate in 2: Discovered Check
This middlegame puzzle comes from the Queen's Gambit Declined Exchange Variation and shows how a discovered check can create a forcing mating net. White’s pieces are already active, and the black king has limited room once the checking piece appears. The key idea is to use a forcing move that also opens a line for another attacker, turning a tactical check into a direct mate threat. Patterns like double check and bishop-and-knight coordination are especially important here.
