"description": "Pilot tournament for fast correspondence series as part of parent group (OGS Teaching Ladder). Feel free to pause your games if you and your opponent are on different time zones, but don't take too long, and try to make use of conditional moves.\n\nYou can also ask me or a mod to mess around with your scores (make unfinishable games draws, etc), through PM. I'm not sure of the extent of my powers, but I will try to help as much as I can.\n\nAssuming full use of time over 250 moves, you will be required to make 10 moves every day, and so will your opponent. The tournament is projected to end within 60 days.\n\nHave fun, keep a malkovich log if you like, and try to review your games!",
