=Editions=  =Hardware Limit= In 2009, ICGA president David Levy surprised potential participants of the WCCC 2009 with an disputed short term decision, an [|8-cores] hardware limit, a topic heavily discussed in various CC forums. As a consequence, the ICGA initiated an opinion formation related to that issue with respect to future World Computer Chess Championships.  =World Chess Software Championship= In September 2009, the ICGA announced following decision :
