But it is not legal to claim something strongest without clear proof. I did some
research on that, the term is called "Alleinstellungswerbung" in german.

Some sites may be interesting for you and others to read (everything in german)

I may quote also some of the additional infos about Ruffian given at
http://www.playwitharena.com:

>>>>>>>>>>>>>>>>>>>>>>>>
Ruffian 2.0.0 by Per-Ola Valfridsson (Sweden) is the strongest Winboard
compatible engine in the world today. The freely available and downloadable
version of Ruffian (ver. 1.0.5) is placed first on the Winboard Engines Rating
List. Its successor, coming more than one year later, with improved features and
much higher playing strength, compared with 1.0.5.
<<<<<<<<<<<<<<<<<<<<<<<<

To hold this way of advertising you must proof it. I am quite sure that the
statement about Ruffian 2.0 is correct, but it is very hard to proof...
The next statement about v1.0.5 is really problematic - there are several
tourney results which see either Deep Sjeng or The King ahead of Ruffian 1.0.5.
I don't think I must give you a list here, e.g. I have the 4th Edition of
WBEC-Ridderkerk in mind where Deep Sjeng did end up in front of Ruffian or
tourneys of Kurt Utzinger where The King clearly ends higher rated then v1.0.5.
The problematic thing is, that when you do "Alleinstellungswerbung" and it is
unclear then the advertise must proof that you are correct, which seems to me
not possible. Because you must proof that it is way (!) ahead of the competitors
since a long time and this may not change for a long time. The word "today" does
not help in that respect. Such things are unpredictable and I am quite sure that
is the reason why no company in the computer chess business has tried it yet. I
did read many decisions at german courts where such advertisings were forbidden.

Even that is very unclear - give both engines a quad operton and let them
play... can you predict the outcome ? I can't.

Or think about the result at the Dutch Open - yes, Ruffian did win it, but with
the same amount of points as The King, a well known winboard engine. Does that
show superiority ?
Or the result of CCT5 - yes, again Ruffian wins it, but in the final result
table it was only third with lower Buchholz... again, to use
"Alleinstellungswerbung" I think this is not enough. It did win finally the
playoffs and for that fully deserve the 1st place... But again, does that show
superiority ?

>accusations of fraud against a person, by which his reputation is harmed.

Nothing was made in public - someone was just suspicious about some things and
contacted the TD... They reacted according to the rules after looking carefully
over the given facts. Anotherone did not follow the rules. So he was
disqualified because of disrespect to the rules and NOT for any fraud.

Greets, Thomas
