Dominguez is a five-time Cuban national champion, who switched federations to the United States in December, 2018. This super grandmaster’s career features stunning results like that of the victory in Barcelona. He won the Magistral Ciutat de Barcelona tournament, with a performance rating over 2900. Two years later, he won the Capablanca Memorial Tournament, and then became the 2008 World Blitz Champion ahead of top grandmasters like Peter Svidler and Alexander Grischuk.
He went on to win the FIDE Grand Prix in Thessaloniki, Greece while earning thirty rating points in the process. Most recently, Dominguez was part of the team that helped prepare Fabiano Caruana for the 2018 Candidates tournament and then the World Championship match that followed. Dominguez narrowly missed winning the first U.S. Championship in which he appeared last year, finishing just a half point behind Hikaru Nakamura.
