Fencer: Not precisely. Three years ago, they started to introduce it, but at that time, only Exchess set 1 was available and the amazon. (Exchess is only used for the name of the sets of real pieces). The organization of Corus Chess Tournament only agreed to introduce the game with the four pieces Amazon, Empress Princess, Veteran. Now three sets are available and still the organization of Corus does not want to change that. But to get more people interested, it is better to start with a small number of "simple" pieces.

Simultaneously, I started a tournament by correspondence via e-mail which have no limitations, only that there is an advice to use only the real available pieces.

All games are mentioned Superchess (or in Dutch Superschaak).

May be there is a possibility to create the corus variant (with the four pieces) first. You do not have the problem that players have to agree which pieces will be used.

Later, it is perhaps an idea to extend the possibilities, but then you need agreements of both players. For example I am playing a game with 6 different pieces: Veteran (N+K), Duchess (R+K), Counsellor (B+K), Herald (some type of limited bishop), Spy (really strange piece), Spy-catcher (even more strange) and emperor (King with extra possibilities). I am playing this game with karel12 (also playing here).
