Russian Game Discovered Attack Puzzle (Rated 854): Discover Attack — Decisive Material Gain

This middlegame puzzle is a classic example of a discovered attack combined with a queenside tactical breakthrough. White’s pieces are coordinated to exploit a pinned defender and an overloaded queen, creating a forcing sequence that wins material decisively. The key idea is that one piece can move with tempo, uncovering a stronger attack behind it while also removing a critical defender. In positions like this, tactical geometry matters more than raw material count.
