"description": "Friends!\nGroup member Gomagic.org on the OGC, who does not give his name, holds the June tournament \"Silver Phoenix descends from Heaven\". This is an unofficial tournament Gomagic.org . As soon as officials find out about this tournament, he will be immediately banned, and the tournament director will be exiled to the GULAG without the right of early release.\nHave time to register and start playing before this happens.\nInsiders report that the tournament will be accompanied by continuous scandals, intrigues, investigations. Read the messages of the Information Agency \"Frog in the swamp\" and you will be aware of the news.\nEach participant of this unofficial tournament will receive an unofficial prize - a Chinese problem book on weiqi in electronic form.\nSomething about the regulations. Please note that each move adds 8 hours to the time, but no more than 2 days. The time is suspended for the weekend. This means that you have to make three moves a day.\nIn a week, the tournament will have an author's advertising poster.\nGood luck, interesting game and let the strongest win!\nP.S. Faster! I hear a knock on the door... The henchmen of the bloody tyrant Putin have already come for me.",
