Gaioz Nigalidze, famously caught using a mobile phone to assist his play in the 2015 Dubai Open has been banned from all FIDE controlled chess for 3 years, and has been stripped of his GM title. The decision by the FIDE Ethics Commission is the first case heard under the new FIDE Anti-Cheating Regulations, that were adopted late last year.
As a first (proven) offence the 3 year penalty is the maximum under the guidelines, although the loss of title is probably a little bit more surprising to anyone unfamiliar with the new regulations. It is included in the list of punishments, although Nigalidze was a little lucky that the Ethics Commission felt he co-operated with the investigation, as he has kept his IM title (which could have been stripped as well).
As the first major case, this will of course provoke a degree of discussion on the appropriateness or effectiveness of the punishment. I suspect for top level players the loss of title is likely to be the greater deterrent, along with the ensuing bad publicity. For lower ranked players (those without titles), it is the length of suspension that will obviously hurt.
