Historical notesThe chameleon was invented by Robert Abbott for his game Ultima . The rules for Ultima were first published in 1962.
See also another piece also called Chameleon.
MovementThe chameleon moves as a chess queen, but does not capture this way, and can never move to an occupied square. When a chameleon captures, it does so by capturing in the manner of piece it is capturing. Chameleons can not capture other chameleons. (In Ultima, a chameleon can not capture an immobilizer, but can immobilize it.)
Movement diagramIn the diagram below, the chameleon (represented by the symbol for the bishop, since the game Ultima uses a chess bishop to represent the chameleon) can move to any of the circles marked with a black circle. It can also capture the rook or the bishop.
RemarksA piece can never attack the chameleon without being attacked back, but conversely, the chameleon can never attack another piece without being attacked back also. A king can never move next to an enemy chameleon.
Note from David Howe: The diagram does not seem right. The black rook is a coordinator, which the white chameleon cannot coordinate with its king. The black bishop is another chameleon, which the white chameleon cannot capture. Ah, now I get it -- they're ortho-chess pieces. Should be using Ultima pieces, otherwise the diagram is misleading.
