Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic discovered attack: one piece moves with tempo, uncovering a stronger line for a rook or bishop behind it. The key idea is that the opponent’s king and queen are overloaded, so a forcing check can drag the king into a worse square and expose a major piece. In positions like this, tactical accuracy matters more than material count, because the hidden attacker creates a decisive swing.
