You may recall that German GM Falko Bindrich was caught last fall having a smart phone and making many trips to the restroom during his game in a Bundesliga match. Now the German Chess Federation has banned him from tournaments and any other sort of official chess participation for the next two years. He has appealed against the severity of the punishment, though without protesting the original forfeiture.
