Piececlopedia: Chameleon

Historical notes

The 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.

Movement

The 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 diagram

In 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.









Remarks

A 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.
