"description": "☆ The default tournament pairing method is Strength, to ensure matches remain competitive the entire contest.\n \n☆ This is a ‘Fast Correspondence Tournament’. Please, avoid delaying your games using the vacation feature or pause. If that’s the case, the tournament director may call the game for your opponent (always with previous notice).\n \n☆ Does NOT pause on the weekend.\n \n☆ If this sounds like a good time to you, please join us!\n\n<HR><BR>\nTournaments are a great way to find people who are more competitive than your average opponent. A big part of improving your own skills is by having them tested by capable adversaries.
