"description": "<link rel=\"stylesheet\" type=\"text/css\" href=\"https://yewang.github.io/ProfileCSS/profile.css\">\n\nFriends!\n\nGrandpa Frog, who is an official member of the Gomagic.org group on the OGS, is holding an unofficial January (2023) Gomagic.org \"Everything that arises is destined to disappear\" tournament.\n\nIn this life, I am absolutely certain of only one thing - we are all going to die. I don't just mean the stones on the goban, I mean everything in general. All life on planet Earth and the planet itself will die. Scientists predict that there are only 1-3 billion years left. I beg you, spend the rest of your time wisely. Play Go, take care of your health and take care of your loved ones, do something constructive and get rid of your bad habits. Find a beloved person and raise at least three children with him.\n\nThere will be no scandals, intrigues and investigations at this tournament. I want peace, peace and goodness, although it never happens that way.\n\nAnd now for the nice part. Each participant of this unofficial tournament will receive an unofficial prize - a Chinese Go book in electronic form.\n\nSomething about the rules. Please note that each turn adds 1 day to your time, but not more than 3 days. Time is suspended on weekends. This means you must make one move per day.\n\nSoon the tournament will have an author's 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 two tournaments either. I promise to make it up to you next weekend.\n\nRegards,\nGrandfather Frog.",
