I think you could implement something in Zillions that would work like this
game. My plan would be, program 3 players: the computer has to play first,
then the user, then a 'neutral' player. The computer's moves would take
place on an invisible 'side' board, then the human player would make a
move (not having been able to see the computer's move: you'd have to
close the panel that shows the move notations), and then the 'neutral'
player would make his move, which would always be to transfer the
computer's moves from the invisible board to the visible one. If the
transfer caused conflicts the neutral player would have to do something
complicated to resolve them. 

You could never have the computer move second, or zillions would use the
information about the human player's move.
