'''Cancellation of Suspension'''
During the 2003 World Computer Chess Championship in Graz, it was unfortunately necessary for the ICGA to disqualify one of the participants, Fritz Reul, and to impose a suspension on him from taking part in ICGA events. This was because Mr. Reul did not respond positively to a request by the tournament committee to submit his program code for inspection, as required by the ICGA tournament rules.
We are now pleased to announce that Mr Reul has since submitted his program code to the scrutiny of an expert approved by the ICGA tournament committee and that this expert has declared Mr. Reul’s code to be completely above board, with no sign of any copying of code from other known programs. Furthermore Mr. Reul has submitted to the ICGA an apology for what happened in 2003 (see above). The ICGA tournament committee has therefore decided unanimously to lift the suspension on Mr. Reul with immediate effect and to welcome him back for participation in future ICGA events.

==DOCCC 2006==
Reul's new program [[Loop (Program)|Loop]] (32-bit) played the [[DOCCC 2006|26th DOCCC 2006]] in Leiden, represented by [[:Category:Opening Book Author|Opening Book Author]] [[Clemens Keck]], and surprised as runner up behind [[Rybka]] and ahead of [[Hiarcs]].
==WCCC 2007==
Another success was the participation of Loop Amsterdam (64-bit) during the [[WCCC 2007]], also represented by [[Clemens Keck]]. Loop became third behind behind the later disqualified [[Rybka]] and [[Zappa]], ahead of [[Shredder]] and [[GridChess]].
