when you regard the type of my arguing to be in a religious style, then there
should be something wrong with it. That would be not at all the effect I intend
to raise.

You call the FRC castling illogical and unnatural, and you are speaking from
'original' squares, but whithout giving some reasons for that.

One part of the idea of FRC seems to be to have a lot of different starting
positions, which all should have equal importance and originality. Therefore
there are no 'original' squares for king and rook anymore. If you will share
that point of view there is only the decision left whether to support castling
or not.

Pure Shuffle Chess refuses castling, it is strict in that point but by that it
establishes itself as a chess variant which stays not compatible with the
traditional chess game then.

FRC has the goal to be an upper set of chess including traditional chess
consistantly as one of its 960 starting positions. Therefore it has to support
castling in a way that is compatible with common practice. There are some
concurrent proposals on how to perform castling: the cited two-step castling,
which is not possible with the king at files 'b' or 'h', the alternative of
finding the center frontiere between K and R (near to K when odd distance) and
jumping left and right to the neighboured fields, and finally targeting always
the established constellation known from normal chess.

All those three approaches seem to be compatible with classic chess for the
first view. But only the last one is generic asymmetric, which alone will have
mirrored starting positions lead to different games. Traditional chess alwas has
had an asymmetric nature.

That all written above has nothing to do with religion. But I regard this to be
strong arguments for the FRC to be the more consistantly defined upperset for
traditional chess.

And still I am missing arguments from yours which are as strong as the one
described here. You call FRC castling rules 'illocical' and 'unnatural', but so
they finally are not. It always will remain also a decision of taste, to accept
them or not. But having the choice between Fischer Random Chess or Shuffle Chess
my well thought selection always will be FRC.

Regards, Reinhard
