Learn How to Win a Queen: Discovered Attack
This puzzle shows a classic discovered attack in the middlegame, where one forcing move opens a line and exposes a more valuable target behind it. The key idea is that the first move is not the final threat by itself; it removes a defender and creates a direct tactical problem for the opponent. Here, king safety is already compromised, so the attack works because the enemy queen and king become vulnerable at the same time, leading to a decisive material gain.
