Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Scotch Game, Schmidt Variation, where active piece placement creates a tactical shot against the king and queen-side coordination. The key idea is a discovered attack: one piece moves with tempo, opening a line for another attacker while also forcing the opponent’s king to respond. In positions like this, king safety matters more than raw material count, because a single tactical sequence can convert activity into a decisive material gain.
