Learn How to Win Material: Discovered Attack
This middlegame puzzle is about turning a tactical shot into a decisive material gain. White’s last move creates pressure on a queen and a loose pawn, but the deeper point is that the position contains a hidden line of force: once the most obvious capture is made, the board simplifies and a key defender disappears. In classical chess, these tactical refutations often come from active rooks and bishops working together to exploit hanging pieces and an overloaded queen.
