the OGS, is hosting the August (2024) \"Bayun the cat\" tournament with the help of <a href=\"https://Gomagic.org\">GoMagic</a>.</p>\n\n<figure class = \"pic\">\n <img src=\"http://pavelgvozdev.ru/ogs_tournament/Bayun_the_cat/Bayun_the_cat.jpg\" width=500><br>\n <figcaption>Bayun the cat</figcaption>\n</figure>\n\n<p>Bayun the cat is a character of Russian fairy tales, a huge ogre cat with a magic voice. He talks and puts to sleep the approaching travelers with his talking and singing, and those who are not strong enough to resist his magic and who have not prepared for the fight with him, the sorcerer cat kills with iron claws. But the one who can catch the cat will find salvation from all diseases and illnesses - Bayun's tales are healing.</p>\n\n<figure class = \"pic\">\n <img src=\"http://pavelgvozdev.ru/ogs_tournament/Bayun_the_cat/Bayun_the_cat_2.jpg\" width=500><br>\n <figcaption>Bayun the cat</figcaption>\n</figure>\n\n<p>The word Bayun means \"talker, storyteller, eloquent talker\", from the verb bayan, \"to tell, to talk\" (cf. also the verbs bayukat, lulling in the sense of \"to put to sleep\"). In fairy tales it is said that Bayun sits on a high, usually iron pole. The cat dwells far away in the Thirtieth Kingdom or in a lifeless dead forest, where there are no birds or animals.</p>\n\n<figure class = \"pic\">\n <img src=\"http://pavelgvozdev.ru/ogs_tournament/Bayun_the_cat/Bayun_the_cat_3.jpg\" width=500><br>\n <figcaption>Bayun the cat</figcaption>\n</figure>\n\n<p>There are several fairy tales where the main character is given the task of catching a cat; as a rule, such tasks were given with the purpose of ruining a good young man. An encounter with this fairy tale monster threatens imminent death. To capture the magic cat, Ivan-Tsarevich puts on an iron cap and iron gloves. Having defeated and captured the animal, Ivan-Tsarevich takes it to his father's palace. There the defeated cat begins to serve the tsar - to tell tales and heal the tsar with lulling words. </p>\n\n<figure class = \"pic\">\n <img src=\"http://pavelgvozdev.ru/ogs_tournament/Bayun_the_cat/Bayun_the_cat_4.jpg\" width=500><br>\n <figcaption>Bayun the cat</figcaption>\n</figure>\n\n<p>There is a point of view that Bayun the cat is a character invented and constructed in the XIX century, which became a member of the \"national bestiary\", actively invented by the Soviet mass culture. In the future \"folklorization\" and even \"mythologization\" of his image Bayun owes to neo-paganism and modern mass culture. </p>\n\n<figure class = \"pic\">\n <img src=\"http://pavelgvozdev.ru/ogs_tournament/Bayun_the_cat/Bayun_the_cat_5.jpg\" width=500><br>\n <figcaption>Real cats really like to sit on posts.</figcaption>\n</figure>\n\n<p>In the Soviet period, Baiun the cat became a full-fledged character in the collective consciousness of the \"national bestiary\" that had been constructed since the mid-1930s, joining Baba Yaga, Leshy, Serpent Gorynych and Koschei. Under the influence of the movie, Bayun becomes Baba-Yaga's closest assistant.</p>\n\n<p>You can see Kota Bayun in the Soviet cartoon \"Ivashka from the Palace of Pioneers\".</p>\n\n<p>\n<embed src=\"https://www.youtube.com/embed/rMEmuSIH8A8?si=CgMls9477qIUWT-z\" width=\"640\" height=\"480\"><br>\nCartoon \"Ivashka from the Palace of Pioneers\"\n</p>\n\n<p>Bayun the cat, is also a canceled mutant in the \"S.T.A.L.K.E.R.\" series of computer games. (restored in numerous mods, puts approaching stalkers to sleep).</p>\n\n<p>And now about pleasant things, about prizes! First of all, each participant of this unofficial tournament will receive an unofficial prize - a Chinese Go book in electronic form. The link to the book will be posted in the tournament chat for a few days after the tournament starts. Since the chat room is periodically cleared of messages, the link will be removed after some time. If you haven't had a chance to download the book, post in the tournament chat and I'll post the link again.</p>\n\n<p>Second, GoMagic.org has generously sponsored prizes for participants of the unofficial tournaments that I host.These prizes come in the form of coupons, which can be used towards the purchase of GoMagic courses and memberships. In each group of our the third round, participants ranking 1st and 2nd will be awarded these valuable prizes.As the host, I will personally deliver the coupons to the winners via private message on OGS</p>\n\n<p>Something about the regulations. Please note that each move adds 1 day to the time, but no more than 3 days. Time is suspended for the weekend. This means that you have to make one move per day.</p>\n\n<p>\n Regards,<br>\n Grandpa Frog.\n</p>\n\n<a href=\"https://info.flagcounter.com/GURR\"><img
