FIDE titles[edit]
Main article: FIDE titles
- Grandmaster (abbreviated as GM, sometimes International Grandmaster or IGM is used) is awarded to world-class chess masters. Apart from World Champion, Grandmaster is the highest title a chess player can attain. Before FIDE will confer the title on a player, the player must have an Elo chess rating (see below) of at least 2500 at one time and three favorable results (called norms) in tournaments involving other Grandmasters, including some from countries other than the applicant's. There are also other milestones a player can achieve to attain the title, such as winning the World Junior Championship.
- International Master (abbreviated as IM). The conditions are similar to GM, but less demanding. The minimum rating for the IM title is 2400.
- FIDE Master (abbreviated as FM). The usual way for a player to qualify for the FIDE Master title is by achieving a FIDE Rating of 2300 or more.
- Candidate Master (abbreviated as CM). Similar to FM, but with a FIDE Rating of at least 2200.
All the titles listed above are open to men and women. Separate women-only titles, such as Woman Grandmaster (WGM), are also available. Beginning with Nona Gaprindashvili in 1978, many women have also earned the unsegregated GM title.[3]
