If a Queen is captured during one cycle, is it allowed to re-appear during
another? Or must it only be recovered through promotion?
I would think that its capture would remove its potential from the field,
and therefore it can only be recovered through promotion. This would also
be applicable to the other potentials.
An observation: as long as a piece remains undefined, each quantum will
hold its potential. So at the initial position, it is possible each
quantum expresses the power of an Amazon until it is actually moved.
