Greek gift sacrifice

In chess, the Greek gift sacrifice (or classical bishop sacrifice) is a typical sacrifice of a bishop by White playing Bxh7+ or Black playing Bxh2+.

Greek gift sacrifices, or the threat of them, occur relatively frequently in play, especially at the lower levels. One of the most famous examples of the sacrifice is found in the game Edgard Colle versus John O'Hanlon, Nice 1930. Less commonly, a Greek gift sacrifice may be the prelude to a double bishop sacrifice, as seen in the game Lasker versus Bauer, Amsterdam 1889.
