The soviet-born american grandmaster Gata Kamsky is by now the strongest player to confirm his presence in the tournament. Nevertheless he was the runner-up of the World Championship on 1996 and has been USA champion five times (1991, 2010, 2011, 2013 and 2014). Kamsky is still ranked inside the world's top-100 and right now his FIDE ELO is 2673 in classic chess —his maximum was 2763—. It will be interesting to see if we will be able to add the "Ciutat de Barcelona" to his collection of achievements.
