"description": "Friends!\nGrandPa Frog, who is an official member of the group Gomagic.org at the OGS, holds an unofficial October (2022) tournament Gomagic.org \"At the top of Machu Picchu\".\nMany, many years ago, when I was about 35 years old, I started making a list of places to visit. I was then impressed by three places: Machu Picchu, the Royal Trail (El Caminito del Rey) in Malaga and Altai. I have never been to these places. And I won't be there anymore. Nevertheless, I have developed an interest in hiking under a backpack. However, I started hiking after another 15 years. Now I get out into the forest whenever possible. It's very nice in the forest, especially alone and when you can't hear the noise of civilization.\nThere will be no scandals, intrigues and investigations at this tournament. I want calmness, peace and kindness, although it never happens anywhere.\nAnd now about the pleasant. Each participant of this unofficial tournament will receive an unofficial prize - a Chinese book on go in electronic form.\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.\nSoon the tournament will have an author's advertising poster.\nBe careful in the woods, don't get lost. Good luck, interesting game and let the strongest win!\nWith respect,\nGrandPa Frog.",
