Learn How to Discover Attack: Winning Material
This middlegame puzzle is a classic discovered attack idea: one piece moves with tempo, uncovering a stronger line of attack from a rook or bishop behind it. The key is that the opponent’s king and queen are both vulnerable, and a seemingly active defensive resource actually fails because the hidden attacker becomes decisive. In positions like this, tactical motifs such as pins, skewers, and loose pieces often combine to create a winning material gain.
