Ralph Betza 1993. In this co-chess variant, you must move any non-royal unit on a cosquare to another vacant square.
I have not yet implemented the option to plan "illegal" moves which generate cosquares and transportations to get the king out of check.
I have allowed the machine, though not the human player, to forego moving units on cosquares.
This is supposed to be the favorite form of cochess.
These are simple illustrations rather than strong opponents.
