Becoming a CM in chess!
The CM title is awarded to players who achieve an established classical FIDE rating of 2200, although the title is also given to players who perform well at continental or national events. As of 2020 there are roughly 1,700 active candidate masters—a small percentage of the millions of chess players worldwide.
