The Power Report (Part 1 of 3): Korea stars in Nongshim Cup; 22nd Samsung Cup; Meijin Four: Iyama’s brilliancy

Monday October 16, 2017

Korea stars in Nongshim Cup: The opening round of the 19th Nong Shim Spicy Noodles Cup was held in Shenyang City in Liaoning Province in China from September 19 to 22. It was a triumph for Shin Minjun 6P (right) of Korea, who won all four games in this round. He showed that there’s more than one strong player named Shin in Korea. He was born on Jan. 11, 1999 in Busan, became a professional in 2012 and reached 4-dan in 2016. In the same year, he won the 4th King of the New Stars title, which earned him promotion to 5-dan. He was promoted to 6-dan earlier this year. In the Korean qualifying tournament to choose the team for this tournament, he defeated his teacher, Lee Sedol. In the first Nongshim game, he defeated the player, Fan Tingyu, who won seven games in a row in the previous Nongshim Cup.
Results:
Game One (Sept. 19). Shin (W) beat Fan Tingyu 9P (China) by 3.5 points.
Game Two (Sept. 20). Shin (B) beat Yo Seiki (Yu Chengqi) 7P (Japan) by resig.
Game Three (Sept. 21). Shin (B) beat Zhou Ruiyang 9P (China) by resig.
Game Four (Sept. 22). Shin (W) beat Kyo Kagen (Xu Jiayuan) 7P (Japan) by resig.
Time allowance is one hour per player followed by byo-yomi of one minute per move. The remaining members of the Japanese team are Iyama Yuta, Yamashita Keigo, and Ichiriki Ryo. Round Two will be played in Busan, Korea, in November, and Round Three in Shanghai in February.

22nd Samsung Cup: The second and third rounds of the 22nd Samsung Cup were held at the Samsung Confucian Castle Campus in Daejeon City in Korea on September 25 and 26. Two Japanese representatives, Iyama Yuta and 2017.10.16_Samsung Iyama eliminatedYamashita Keigo, had survived the large-scale opening round, but they were both eliminated in the second round. Iyama (B, at left) was matched against Shin Jinseo 8P of Korea. The game featured fierce fighting from early on. Iyama made an oversight and resigned after 118 moves. Yamashita (black) lost to Tong Mengcheng 6P of China; he resigned after 122 moves. Pairings in the semifinals are Dong vs. Gu Zihao (both of China) and Tang Weixing (China) vs. An Kukhyun (Korea)

Meijin Four: Iyama’s brilliancy
As promised, here is some more detail about the 4th game of the current Meijin title match, played on October 2 and 3. Takao Shinji, the challenger, had black. He slipped up in the opening, neglecting to defend a large group because he overlooked a sequence White had to put it into ko. In effect, he had to give White a free move elsewhere when he played an extra move to secure life. That left him a tempo behind in the game, but he played on tenaciously and succeeded in creating complications by leading the game into a large-scale fight. He then played a clever move with Black 101 that seemed to turn the tables in the fight; if White made the “usual” answer, Black had a clever tesuji with move 16 in an unplayed continuation. “Unplayed,” because Iyama came up with a brilliant counter-intuitive combination that enabled him to capture the key stones in the fight at the cost of a couple of sacrifice stones. That gave him the lead. Takao fought on for another 50 moves or so, but was unable to catch up. Iyama even rubbed salt in the wound by making use of the “sacrifice” stones in a later fight. Takao resigned after White 164. The fifth game is already being played on October 16 and 17. It is Takao’s first kadoban, so the second grand slam in Japanese go could be imminent.

Tomorrow: Motoki does well in Kisei knock-out; Chinese pair wins world championship; New Honinbo league starts

AlphaGo-AlphaGo Game 11: A calmer game, with hidden reading

Friday October 13, 2017

“This game is a lot calmer than Game 10,” says Michael Redmond 9p in his game commentary on AlphaGo-AlphaGo Game 11. “There’s a lot of 2017.10.13_ag-ag-thumb-11fighting that doesn’t actually come into the game, but I’ll be showing a lot of variations about things that could have happened, so there’s a lot of, you might say, hidden reading. And then there’s a ko at the end, for the life of a group. ”

The Game 11 video is produced by Michael Wanek and Andrew Jackson. The sgf file was created by Redmond, with editing and transcription by Garlock and Myron Souris.
