Gregory Alexander, a resident of Everett, Wash., used a username and password belonging to Randall Hough, a member of the United States Chess Federation's Board of Directors, according to the U.S. Attorney's Office.
Alexander accessed Hough's private e-mail account on 34 different occasions between November 2007 and June 2008 to obtain information from it, according to the U.S. Attorney's Office.
Alexander is the webmaster of www.chessdiscussion.com, a Web site with a forum for chess players to talk about the game.
Alexander was arrested in San Francisco and made his initial appearance in federal court in San Jose Friday to face charges of computer fraud and aggravated identity theft.
He is currently out of custody on a $100,000 personal recognizance bond, and is scheduled to be in court again at 9 a.m. on Aug. 3, according to the U.S. Attorney's Office.
