The Dutch Computer Chess Association announced that they dont support the sanctions from the ICGA against Rybka or their programmers.


Rybka and the ICGA

Some time ago, the ICGA promulgated that Rybka had been proven to be a Fruit clone; therefore, a liftetime suspension of its programmer had been decided upon.

Moreover, all world titles had been retroactively declared invalid.


Evidently, the primary reflection within the CSVN-board was to acknowledge this suspension as such. The board has insufficient knowledge and, therefore, we chose to rely upon both the authority and the reliability of the ICGA.

At the same time, we allowed ourselves to put some question marks to issues we considered to be well within our grasp.


The decision-making

1. ICGA's decision was prepared by a group of experts; some of its members could gain benefit of the sanctions inflicted upon Rybka;

2. At the subsequent voting, 14 out of 34 persons stated that one could indeed consider Rybka to be a clone.


The evidence

1. The group of experts consisted partially of the same persons who, a few years ago, explicitly stated that Rybka was not a clone. It is indeed very remarkable that experts suddenly change their mind.

2. The version of Rybka that was examined had never been distributed. The versions of Rybka that took part in the World Championships were not examined.

3. None of the other competitors in the World Championships had been examined.


The delay

The program was known by the end of 2005. It is indeed very remarkable that, through abetment of rivalling contenders, action was taken and sanctions were implemented no earlier then 2011.


The degree of punishment

In the world of sport, the doping problem is well known. When doping rules are violated, a first time sanction of one or two years is common practice; Rybka faced a lifetime suspension straightaway.


Of course, the annoucement made by the ICGA immediately gave rise to discussions on the Internet fora.

Those who were in favour of the sanctions were severely questioned by (e.g.) Miguel A. Ballicora, George Speight and Sšren Riis. Their opposition did make an impression on us, because these people can rely upon a vast expertise in the field of chess programming, law and mathematical logic. When finally dutchman Ed Schršder, former world computer chess champion, joined the aforementioned critics of ICGA, we no longer seemed to have a choice.


As mentioned above, we had a number of questions as to the decision-making, the delay, the evidence and the degree of punishment and now, added to all that, the technical justification seemed to falter.


At this very moment, the CSVN board has the most serious doubts as to the rightfulness of ICGA's decision. Therefore, we have chosen not to abide by their sanctions against Rybka.

So it seems Rybka will participate on the 19th World Computer Chess Championship:D

Several highly renowned chess programmer, some commercial competitors of Rybka (partly the same that were sitting in the ICGA Commission of Inquiry) yesterday let the CCC publish a letter in which they explain the CSVN that they do not participate under these circumstances in their tournaments .
Open letter to the CSVN

September 21, 2011

Dear Cock de Gorter, CSVN board and CSVN members,

As past participants of the CSVN tournaments we feel that your decision to allow Rybka back in your tournaments is ill-reasoned and damaging to computer chess. Your statements regarding the decision-making are misleading and those about the evidence are all factually false:


The ICGA panel consisted of experienced computer chess specialists, some commercial, some hobbyists, and some pure academics. At the end of the investigation, not a single person in the panel said that they believed Vasik Rajlich was innocent.


Experts who have long-defended Vasik Rajlich have changed their minds because the investigation results leaves them no doubt regarding his breaking of rule 2 of the ICGA: Rybka is a without a shred of doubt a direct derivative of Crafty/Fruit and Mr. Rajlich concealed these origins from the Tournament Director. Furthermore, he has not provided any clarification for the found similarities.


All Rybka executables considered in the investigation were distributed to rating lists and/or users. Version 2.3.2a participated in the 2007 WCCC.


In the past the ICGA has investigated entries that raised suspicion and for which a complaint was filed by one of the participants. Cheaters have been caught before and Rybka is no exception.

The sanctioning of Rybka is upsetting news for all involved in computer chess. The public condemnation of a many-times World Champion and well-known representative of the field does not reflect well on the field’s image. The decision to ban Rybka was consequently not taken lightly.

However, it is unacceptable to us that you base your decision making on opinionated Internet postings and put aside the extensive expertise that the ICGA has gathered. Your lack of judgment, which is further exemplified by your recent handling of the Junior/HIARCS incident, is a sign that your once-respectable tournaments are not in good hands any more. Under the current direction we can therefore not enter your tournaments.

Old news. Was posted a month ago at various fora including here (http://immortalchess.net/forum/showpost.php?p=159062&postcount=41).
So it seems Rybka will participate on the 19th World Computer Chess Championship
Nothing to do with the WCCC. CSVN's decision is about the 31st Open Dutch Computer Chess Championship (http://www.computerschaak.nl/index.php?option=com_content&view=article&id=515%3A31e-open-nederlands-kampioenschap-computerschaak-2011-&catid=51%3Atoernooien&Itemid=28&lang=en)

Again this boycott relates to the Dutch Open and has nothing to do with the WCCC. The WCCC announcement on the ICGA website is below.
