International grandmaster
Extracted from the Wikipedia article Grandmaster (chess).
Official status (1950 onwards)
In 1950 FIDE created the titles of Grandmaster (GM), International Master (IM) and Woman Master (WM, later known as Woman International Master or WIM). The grandmaster title is sometimes called "International Grandmaster" (IGM), possibly to distinguish it from similar national titles, but the shortened form is far more common today.
