Learn How to Win a Crushing Discovered Attack: Petrov Defense
This Petrov Defense puzzle shows how a seemingly active queen can become a tactical target when the position opens up. The key idea is a discovered attack: one piece moves with tempo, exposing a stronger line of attack behind it. Here, the kingside is vulnerable, and Black can use forcing moves to create a decisive material gain while keeping White’s queen under pressure. In classical chess, these short tactical sequences often decide the middlegame immediately.
