Decoy (chess)

In chess, a decoy is a tactic that lures an enemy man off its square and away from its defensive role.^[1] Typically this means away from a square on which it defends another piece or threat. The tactic is also called a deflection. Usually the piece is decoyed to a particular square via the sacrifice of a piece on that square. A piece so sacrificed is called a decoy. When the piece decoyed or deflected is the king, the tactic is known as attraction. In general in the middlegame, the sacrifice of a decoy piece is called a diversionary sacrifice.^[2]
