Premium Chess
Premium Chess is a commercial Internet chess server that specializes in platforms for chess federations. It is composed of one commercial playing platform, Premium Chess online arena, the commercial chess playing platforms of the World Chess Federation, FIDE, and three national chess federations (Italy, Brazil and the Czech Republic). FIDE and the three national chess federations award official online federation chess ratings for bullet, blitz and rapid games played between two full members on their respective online platforms. All other games are unrated or for unofficial server ratings. Premium Chess features an automatic anti-cheating system, AceGuard, that monitors all games played by full members. In his announcement for the beta version of FIDE Online Arena, FIDE President Kirsan Ilyumzhinov stated that the awarding of official FIDE ratings for online chess had not been possible before the introduction of this system because of the previous difficulty in detecting cheating. Premium Chess uses a Java-based application and activities include individual challenge games, challenge game matches, Sit & Go tournaments, scheduled tournaments, training facilities, simultaneous exhibitions and master challenges.
