[Retros] Castling temporarily changed and repetition of position

[Rol, Guus]

Did anybody ever notice that a miniature copy of the castling issue
exists for the e.p. issue? It is possible to have a situation where the
'permanent' e.p. right exists, which is however 'temporarily'
unavailable since it will put the player in selfcheck. Clearly the
designations 'permanent' and 'temporarily' are misleading here - which
is why I prefer a different terminology - but the underlying question is
real. Strict application of 9.2 tells us that repeating a position with
an e.p. right that is non-executable is different from repeating a
position with an e.p. right that is executable. But if you substitute
"castling right" for "e.p. right" in the previous sentence then the two
scenarios are considered equivalent. Peculiar, to say the least!

Guus Rol.

I agree. The permanent right to castle has changed.
But the temporary right will not change with positions where pieces are
on the same squares with same mobility.

That would be better.

If only this was the case...

Wow! That sounds strange... I can understand they don't want to consider
composition related issues (forced mate when the flag fall...), that
will never happen in "real" play. But if M. Gijssen proposed it and it
was refused, maybe it's because of political problems, the lobbying you
speak of, and that's sad.

What is that?
