In some motifs she is described as a repulsive or fierce-looking old woman who roasts and eats children, while in others she is a sweet old woman who helps the hero.</p>\n\n<p>In East Slavic fairy tales, Baba Yaga is an old woman with supernatural powers and associated with the world of the dead, as evidenced by her appearance, place of residence and main functions. Her characteristic features are old age, decrepitude and ugliness (nose in the ceiling), emphasized female physiology (breasts hanging over the threshold). An important feature of Baba-Yaga is her one-legged or bone (less often - iron, wooden) leg, i.e. dead, devoid of flesh, which brings the character closer to other one-legged creatures of world mythology, having snake origin. There is a reason to consider Baba Yaga blind, as she recognizes the approach of a man by his smell. Baba Yaga's permanent attributes are a bread shovel, on which she tries to roast the hero, an oven, and a stupa, in which she moves with the help of a pestle.</p>\n\n<figure class = \"pic\">\n    <img src=\"https://pavelgvozdev.ru/ogs_tournament/babayaga/BabaYaga_2.jpg\" width=500>\n    <figcaption>Georgy Milyar as Baba Yaga.</figcaption>\n</figure>\n\n<p>Baba Yaga's dwelling is a cramped hut, which stands on poles or goat (goat, sheep) legs or on one leg, sometimes propped up with pancakes. The bird legs of the hut have no definite explanation, their erection to tree trunks with roots, on which forest benches were placed, is doubtful. The fence around the hut consists of human bones and skulls. Baba-Yaga lies in the hut on the floor, on a bench or on the stove, occupying almost the entire space (resting her head on one wall and her feet on the other), which brings her dwelling closer to a coffin, and Baba-Yaga herself to a dead man. The hut is located on the border of the forest, being the only passageway between the human and the otherworld (\"Tridevyatiye Tsarstvo\"), where the hero of the fairy tale must get to solve a magical problem. The hut has its doors turned towards the forest, so to enter, the hero must turn its front part towards himself with the help of a special formula, and also pass a test with Baba Yaga, who at first intends to eat him. But the hero demonstrates correct behavior, wins, and humbles Baba-Yaga, who after that is forced to help him.</p>\n\n<figure class = \"pic\">\n    <img src=\"https://pavelgvozdev.ru/ogs_tournament/babayaga/Hut.jpg\" width=500>\n    <figcaption>Baba Yaga's dwelling is a hut on chicken legs.</figcaption>\n</figure>\n\n<figure class = \"pic\">\n    <img src=\"https://pavelgvozdev.ru/ogs_tournament/babayaga/Hut_2.jpg\" width=500>\n    <figcaption>This is what a hut on chicken legs could really be like.</figcaption>\n</figure>\n\n<p>The best embodied the image of Baba Yaga in feature films was Soviet actor Georgy Frantsevich Milyar.</p>\n\n<figure class = \"pic\">\n    <img src=\"https://pavelgvozdev.ru/ogs_tournament/babayaga/Milyar.jpg\" width=500>\n    <figcaption>Georgy Milyar</figcaption>\n</figure>\n\n<p>His most famous role - Baba Yaga - he played in Alexander Rowe's movie \"Vasilisa the Beautiful\". On it tried many actresses, including Faina Ranevskaya. But the director refused to all: he was afraid that Baba Yaga in their performance will not be scary enough, will not scare the audience. Then she volunteered to play Milyar: \"It is not a female role. Tell me, what actress will allow to make herself so scary on the screen? And I'll bear it all.\"</p>\n\n<figure class = \"pic\">\n    <img src=\"https://pavelgvozdev.ru/ogs_tournament/babayaga/BabaYaga_3.jpg\" width=500>\n    <figcaption>Georgy Milyar as Baba Yaga.</figcaption>\n</figure>\n\n<p>The artist carefully prepared for the role of Baba Yaga. He watched how to move and talk to older women. Milyar recalled: \"Abundant material gave me a neighbor in the communal room. Character she was terrible, squabbling, she had to be sure someone to quarrel.\" Imitated the actor and one old lady, which he saw in Yalta.</p>\n\n<p>The role of Baba Yaga glorified Milyar. After \"Vasilisa the Beautiful\" he played this character several times in other movies-fairy tales Rowe. The actor called Baba Yaga his favorite hero.</p>\n\n<p>After the role of Baba Yaga Georgi Milyaru began to offer only negative characters. The actor wrote: \"I work in the field of fairy tales, I represent all the unclean force in the Soviet cinema\".</p>\n\n<p>You can watch the movie \"Vasilisa the Beautiful\" here:</p>\n\n<p>\n    <embed src=\"https://www.youtube.com/embed/Gzr794xxtDg?si=h_Nozi0-W2Vwkm7P\" width=\"640\" height=\"480\">\n</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\n<p>\n    Regards,<br>\n    Grandpa Frog.\n</p>\n\n<a href=\"https://info.flagcounter.com/wxFT\"><img src=\"https://s01.flagcounter.com/count2/wxFT/bg_FFFFFF/txt_000000/border_CCCCCC/columns_4/maxflags_40/viewers_0/labels_0/pageviews_0/flags_0/percent_0/\" alt=\"Flag Counter\" border=\"0\"></a>\n\n<p>P.S. <strike>James Bond will return in the movie \"From Russia with love\"~~</strike></p>\n\n<p>Tournaments <a href=\"https://Go magic.org \">Go Magic</a> will continue in March with the \"Jazz Standard - Mack the Knife\" tournament.</p>",

This was the first jazz theme written in 5/4, and it was included on the 1959 album Time Out. Let me remind you that Dave Brubeck specifically created pieces in tricky sizes - 9/8, 6/4, 7/4 or used variable sizes (two bars by three, two bars by two). And in this experiment, the most popular theme was 5/4.</p>\n\n<figure class = \"pic\">\n    <img src=\"http://pavelgvozdev.ru/ogs_tournament/Jazz_standards_Take_Five/Take_five_2.jpg\" width=500>\n    <figcaption>The Dave Brubeck Quartet.</figcaption>\n</figure>\n\n<p>Of course “five” is in the title for a reason, but actually Take Five means “five minute break”. The fact that such a theme could become a hit and that it became a household name at musical gatherings is amazing, but if you think about it, isn't that proof that jazz is no longer a music for dancing? It's no coincidence that the Brubeck Quartet achieved its greatest popularity among American intellectuals, and its concerts were most often a success with student audiences.</p>\n\n<figure class = \"pic\">\n    <img src=\"http://pavelgvozdev.ru/ogs_tournament/Jazz_standards_Take_Five/Take_five.jpg\" width=500>\n    <figcaption>Dave Brubeck</figcaption>\n</figure>\n\n<p>Later, arrangements for big bands emerged, and vocal versions also appeared. Of these, the most successful, in the opinion of jazz lovers, is Al Jarreau's 1977 recording (Over the Ranibow album). But I recommend listening to the original Brubeck Quartet recording. Joe Morello on drums, Gene Wright on double bass, and Desmond on saxophone.</p>\n\n<p>\n<embed src=\"https://www.youtube.com/embed/tT9Eh8wNMkw?si=uaG2XthjQUYn3w5P\" width=\"640\" height=\"480\"><br>\nOriginal Brubeck Quartet recording\n</p>\n\n<p>Paul Desmond (1924-1977) was an alto saxophonist, one of the brightest representatives of cool jazz, popular in the early fifties on the West Coast of the United States.</p>\n\n<p>In 1951-1967 he played in the Brubeck Quartet, his improvisations were characterized by striking melody and impeccable logic of development.\" I don't know why my sax produces such a sound, such a tone,\" Desmond admitted, \"Sometimes I think I'm playing illegally. The Take Five theme brought the saxophonist amazing success and huge royalties, which, incidentally, he donated to the Red Cross.In 1951-1967 he played in the Brubeck Quartet, his improvisations were characterized by striking melody and impeccable logic of development.\" I don't know why my sax produces such a sound, such a tone,\" Desmond admitted, \"Sometimes I think I'm playing illegally.

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/Nxt0\"><img src=\"https://s01.flagcounter.com/count2/Nxt0/bg_FFFFFF/txt_000000/border_CCCCCC/columns_4/maxflags_50/viewers_0/labels_0/pageviews_0/flags_0/percent_0/\" alt=\"Flag Counter\" border=\"0\"></a>\n\n<p>P.S. <strike>James Bond will return in the movie \"From Russia with love\"~~</strike></p>\n\n<p>Tournaments <a href=\"https://Go magic.org \">Go Magic</a> will continue in August with the \"Bayun the cat\" tournament.</p>",

Please notice I’m experimenting with a new time structure. Moves only gain you 12 hours time, but I did allow the time to pause on weekends. Hopefully this will allow the tournament to go a little faster, without adding stress. Let me know what you think. Happy Go everyone!",
