MTEL MASTERS
Super tournament organised between 2005 and 2009 in Sofia, Bulgaria, sponsored by the national telecom company MTEL.
One particuliarity of the rules is that the players should not offer draws directly to their opponents. Draw-offers will be allowed only through the Chief-Arbiter in three cases: a triple-repetition of the position, a perpetual check and in theoretically drawn positions.
The winners were: 2005 Veselin Topalov, 2006 Veselin Topalov, 2007 Veselin Topalov, 2008 Vassily Ivanchuk and 2009 Alexey Shirov.
