A variant on Andernach chess is anti-Andernach, in which pieces except kings change colour after non-captures, but stay the same colour after a capture. There is also super-Andernach in which all pieces except kings change colour after every move, whether a capture or not. Super-Andernach was introduced by John Rice in ''The Problemist Supplement'' in March 2006.
