Fabien,

that is only partially right.

X-FEN is not part of the UCI PROTOCOL. But FEN is. Thus the newly extension
for FRC is self contradicting and could not be a STANDARD. There is still some
work to do. It does not make sense, that there are positions, which by that
UCI extension should be encoded differently than if seen from the traditional
point of view. An example are the 18 so called Pseudo-FRC starting arrays and
all thinkable follow-up positions.

Regards, Reinhard.
