Sebastien Feller (born 11 March 1991) is a French-born chess Grandmaster.
Sebastien Feller was born in Thionville, France on March 11, 1991.
Feller achieved both his International Master and Grandmaster titles in 2007 at age 17. He won the French Junior Championship 2007 and was vice-champion of the European U16 Championships 2007. He played as the 1st reserve for France in the European Team Championships 2009 held in Novi Sad, Serbia scoring +4 =4 -1. He was also French Blitz Champion 2010 and winner of the Paris championship in July 2010. In 2010, he represented France in the 39th Chess Olympiad in Khanty-Mansiysk, Russia but was found guilty of cheating by the French Chess Federation (FFE).
In October 2010, Feller scored 6/9 (+5 =2 -2) during the 39th Chess Olympiad and won the Gold medal for best individual performance on board 5. However, the French Chess Federation accused Feller, along with French players GM Arnaud Hauchard and IM Cyril Marzolo, of cheating during the Olympiad. While Feller was in the playing hall, Marzolo was in France where he checked the best moves on the computer. Marzolo then allegedly sent the move in coded pairs of numbers by SMS to Hauchard. Once Hauchard had the suggested move, he would position himself in the hall behind one of the other players’ tables in a predefined coded system, where each table represented a move to play. The French Chess Federation claims, in all, 200 text messages were sent during the tournament. The scam was supposedly uncovered by Joanna Pomian, the federation's vice-president.
Feller has released a statement (in French) in defense of himself:
Official Statement of GM Sebastien Feller (translated)
The French Chess Federation has taken disciplinary measures against the three players. These measures were later revoked by a French civil court due to technicalities. In July 2012 the FIDE Ethic Commission sanctioned all three players and ruled "Mr. Sébastien FELLER has to be sanctioned with the exclusion from the participation in all FIDE tournaments, as a player or as a member of a national delegation, for a period of 2 (two) years and 9 (nine) months, starting from the 1st of August 2012".
