Grandmaster (chess)

The title Grandmaster is awarded to chess players by the world chess organization FIDE. Apart from World Champion, Grandmaster is the highest title a chess player can attain.

Once achieved, the title is held for life. In chess literature it is usually abbreviated to GM. (Other titles are also often abbreviated: FM for FIDE Master, IM for International Master, and CM for Candidate Master.) The abbreviation IGM for International Grandmaster is also sometimes used, particularly in older literature.

Grandmaster, International Master, and FIDE Master are open to both men and women. In 1978, Women's World Champion Nona Gaprindashvili became the first woman to receive the GM title, by a special decision of FIDE. The first woman to qualify for the title through achievement in tournament play was Susan Polgar in 1991. Since about 2000, most of the top 10 women have held the GM title.

A separate gender-segregated title, Woman Grandmaster (WGM), is also available. It is awarded to women who attain a level of skill between that of a FIDE Master and an International Master.
