What is Greek Gift Sacrifice?

The Greek Gift Sacrifice is a term used in chess referring to a scenario where a player sacrifices their bishop by placing it on the opponent's h7 or h2 square, typically leading to a severe weakening of the opponent's kingside. Named after the classical legend of the Trojan Horse, it's generally part of a larger strategy to gain a significant advantage in position or to set up a potential checkmate. The sacrifice often results in the opportunity for the attacking player to perform a successful checkmate by utilizing their other pieces effectively.
