The amazon, also known as the queen+knight compound or the dragon, is a fairy chess piece that can move like a queen or a knight. It may thus be considered the sum of all orthodox chess pieces other than the king (because it cannot castle and does not know when it is under threat via the check rule) and the pawn (because it cannot practice en passant). The amazon can force checkmate on an enemy king without the help of any other friendly piece.
Chess moves in this article use A as notation for the amazon.
