What is the ACO?
The Amateur Chess Organization is the organization for amateur chess players up to 2400 rating points.

For whom has the ACO been founded?
99% of all chess players have got less than 2400 rating points and do not earn a living from chess. The ACO has been founded for this biggest group of chess players, the amateurs.

Why has the ACO been founded?
As the vast majority of chess players are amateurs and as there has been no chess organization in the past that exclusively represents the interests of amateur chess players, the establishment of the ACO was a necessary consequence.
