When this tournament starts, in the Siberian village of Bakhta, that in the middle reaches of the Yenisei River, it will be about -30 degrees below zero. But people live there and live well. But they probably don't play go. A wonderful documentary film \"Happy People\" was shot about the lives of these people in the very center of Russia. You can view it here: https://www.youtube.com/watch?v=bITElb4l_SY&t=22s&ab_channel=ДмитрийВасюков\n\nPlay go, take care of your health and take care of your loved ones.\n\nThere will be no scandals, intrigues and investigations at this tournament. I want calmness, peace and kindness, although it never happens anywhere.\n\nAnd now about the pleasant. Each participant of this unofficial tournament will receive an unofficial prize - a Chinese book on go in electronic form.\n\nSomething about the regulations. Please note that each move adds 1 day to the time, but no more than 3 days. The time is suspended for the weekend. This means that you have to make one move a day.\n\nSoon the tournament will have an author's advertising poster. Yes, I always promise a poster for each tournament, but I only drew them for the first two. I didn't give the promised prizes for the last tournaments either. I promise to improve next weekend.\n\nWith respect,\nGrandPa Frog.",
