As they say: 'Assuming makes an ass out of you and me'.

Regulations allow this wether you like it or not. The same can happen to Diep,
XiniX or any of the other participants. In the past several clones have been
identified this way (bionic, deep<9> and Djenghis come to mind) so why not? Of
course, such accusations are never a positive thing, but if the work is original
there should be no problem proving it.

So what's this with you and 'Voyager' that vincent mentions in
http://www.talkchess.com/forums/1/message.html?321224 ? The only reference I
could find is
http://lists.debian.org/debian-devel/1999/debian-devel-199905/msg00127.html

"These
persons are downloading the source *** maybe *** changing two or three
lines, recompiling the source, giving it a different name like "voyager"
or "bionic impakt", and then entering the resulting executable in chess
competitions."
A search on "voyager Vidanovic" the CCC search engine only turned up one result
containing:
"My opinion was not right. But I am not a programmer and I have not see it.
Look,
we spent hours of time for test Voyager and I am very disappointed about
Gabriele Müller (also Prof. Djordje Vidanovic and other persons)."

What's so bad about verifying wether a new program is a clone or not? I hope
your opinion and actions on this matter have nothing to do with this 'voyager'
program. Since this is Ruffian's first real-life tournament it doesn't seem odd
that some people still have doubts and would like to be convinced before playing
it in the tournament.

OTOH, FYI it doesn't in mine. No ?, ! or even the move itself.
"OTOH," just a reminder, you stated that it exists in all Diep 2.x in at least
two forums. This seems odd, very odd.

I suppose no one could have tinkered with it prior to sending it to you. Perhaps
Santa Claus is involved.

I agree, after verifying the program is original should there be any doubt
thereof.

I haven't seen any public complaints from both Vincent and Tony regarding "a
clone named ruffian" participating in the dutch championship. OTOH, you did drag
this 'vendetta' with Diepeveen into CCC and at least one other forum. Why not
follow their example and keep it where it belongs, in email f.i.
