The Association of Chess Professionals (ACP) was founded in 2003 to represent professional chess players in discussions with FIDE and other chess organizers. Its motto was 'Injustice done to one is a threat to all'.
The ACP's first elected officers were Joel Lautier (President), Bartlomiej Macieja (Secretary), and Almira Skripchenko (Treasurer). In 2004, it organized the ACP Tour, which it described as 'a tournament circuit to regroup all important tournaments in the world, during a one-year chess season. Players taking part in these events gain points according to a ranking system'.
