Learn How to Spot a Discovered Attack: Mate in 2
This middlegame puzzle is a classic example of a discovered attack turning into a mating net. One piece can move with tempo, opening a line for a stronger attacker behind it and forcing the king into a helpless position. The key idea is that the first move is not just a check, but a clearance move that exposes the king and overloads the defender. In tactical positions like this, king safety matters more than material.
