Every move imitates the ability of the piece moved before, except the
first move for nothing is before it. What if time is circular, in that
spirit I propose the following variant:
As a first move, any piece can be moved with any power, however this
implies the last move must be made with a piece with such power, and
any move during the game that would make such a ending impossible is
declared illeagal.
