"description": "<link rel=\"stylesheet\" type=\"text/css\" href=\"https://yewang.github.io/ProfileCSS/profile.css\">\nFriends!\n\nGrandpa Frog, who is an official member of the Gomagic.org group on the OGS, is holding an unofficial February (2023) Gomagic.org \"February Frosts!\" tournament.\n\nIn the olden days, the Slavs called the last winter month fierce - because of the particularly severe February frosts. February frosts have always been stronger than Christmas and Epiphany frosts. There are Russian proverbs \"February is a fierce month: he asks like he has shoes\" and \"February has two friends: a snowstorm and a blizzard\" (\"Февраль — месяц лютый: спрашивает, как обутый\" и \"У февраля два друга: метель да вьюга\"). These proverbs rhyme in Russian.\n\nThis year, Oleneksky District of Yakutia recorded the lowest temperature in Russia since the beginning of the season. On January 10 the thermometer showed -62! Even in Oymyakon, which is considered the \"center of cold\" in Russia, the temperature was \"warmer\" (-59).\n\nThe settlement is located above the Arctic Circle. On these days the sun doesn't rise there at all. Thus, the 60-degree frost holds all day long!\n\nThis is January, we are cautiously waiting for February frosts.\n\nIn other countries there is an anecdote that bears walk on the streets in Russia. This is true, but they walk the streets rarely.\n\nFor example, there was such an interesting case, a polar bear ran into one of the entrances of an apartment building on the Novaya Zemlya archipelago in the Arkhangelsk region.\nhttps://www.youtube.com/watch?v=J2k57rbd0dg\n\nBears on the streets can sometimes be found in large cities. For example, in the Russian capital, Moscow.\nhttps://www.youtube.com/watch?v=DPtSt1JEZ2g\n\nI personally have never seen bears on the streets. In my city, cats, dogs and horses walk the streets. And what animals walk the streets of your hometown?\n\nThere will be no scandals, intrigue and investigations at this tournament. I want peace and quiet, peace and weiqi, though it never happens anywhere.\n\nAnd now for the good stuff. 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 that you must make one move per day.\n\nRegards,\nGrandfather Frog.",
