Peter, thank you so much for the dedication! (JV)

Definitions:

Anti-Circe: After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). R, B & S go to the square of the same colour as the capture; Ps stay on the file of capture; fairy pieces go to the promotion square of the file of capture.

Isardam: Any move, including capture of the King, is Isardam illegal if a Madrasi-type paralysis would result from it.
Madrasi: Units, other than Kings, are paralysed when they attack each other. Paralysed units cannot move, capture or give check, their only power being that of causing paralysis.

Transmuted Kings: When they are threatened, the Kings move only like the threatening unit(s).
