Life Master
From Wikipedia, the free encyclopedia
Life Master is a chess title awarded by the United States Chess Federation. To be awarded this title, one must hold a master's rating of over 2200 for at least 300 tournament chess games.
During the first half of the 1990s, the USCF also awarded a "Life Master" title on the basis of a different and more complex system. This "class norm" system was later discontinued, and players who had or were subsequently granted the title on the 300-game basis were renamed "Original Life Masters." In practice, the distinction is rarely made.
