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.
Since the USCF Policy Board changed its rules to award the Life Master title to anyone who had ever held the master title for even one game, the Life Master title is now known as the OLM Title, which stands for "Original Life Master".
