Learn How to Spot a Discovered Attack: Mate in 2
This middlegame puzzle shows how a discovered attack can create a mating net when the enemy king is boxed in by its own pieces. White’s knight jump is not just a check; it also clears a line for the queen to strike the kingside. Black’s king safety is already fragile, so one forcing move can overload the defense and leave the h7 square vulnerable. The key idea is that a tactical check can also be a clearance move for a second threat.
