What is Philidor Sacrifice?

The Philidor Sacrifice is a chess tactic named after François-André Danican Philidor. It refers to a tactic that encompasses a bishop sacrifice at h7, often followed by Ng5+ and Qh5, creating a powerful attack against black's castled king position. This typically involves the queen and knight coordinating to create an aggressive and sometimes game-winning attack. The Philidor Sacrifice is designed to expose and exploit weaknesses in the opponent's position, often leading to faster checkmate or material advantage.
