Didn't find an existing thread even though the event has advanced to the quarterfinal stage. The quarterfinal and semifinal matches will be going on tomorrow and then 2 days after. Here are the matchups: Ke Jie vs. Shin Jinseo Xie Erhao vs. Choi Cheolhan Jiang Weijie vs. Lee Wonyoung Yang Tingxin vs. Iyama Yuta Some intriguing storylines: another chance for Ke Jie to win a world title in 2017 (Has one more in the inaugural Shinyao Cup at the end of the year), the potential for Shin and Iyama to finally break through, and two more young Chinese players in the mix. Also Jiang won his only world title here and has beaten Lee Sedol and Park Junghwan to get to the quarter, while Lee Wonyoung beat the defending champ Dang Yifei and then Tang Weixing. |

I think there was some coverage of previous rounds in the Iyama and Ke Jie threads. Winner in bold: Ke Jie vs. Shin Jinseo Xie Erhao vs. Choi Cheolhan Jiang Weijie vs. Lee Wonyoung Yang Tingxin vs. Iyama Yuta |

Game Jiang-Lee, from WBaduk the results, show Jiang won by 0.5 Game Iyama, glad to see him win, I was somehow worried for his dragon when I watched the middle game, but as usual (not always though), he found a good tesuji to escape. Yang probably thought he can do a probing move threaten to connect his 3 stones on the left, but Iyama showed his determination with the cut. After that exchange I think the fight is already good for him. So the semi match-up is Iyama - Ke Jie, right? Ke Jie is obviously stronger, but I think Iyama has slightly better chance against Ke than against Shin, in the last encounter Shin somehow destroyed him. |

Ke Jie's game was a nice example of his new territory-oriented style inspired by AlphaGo: he (as white) started with a 3-3 and 3-4, early invaded a 4-4, and then reduced the moyo (with a 5th line shoulder hit) which ended in a trade of him getting some corner and Shin getting thick (initial 5th line shoulder hit sacrificed) and keeping the other half of the moyo. But Ke reduced that too later and Shin resisted resulting in Ke burrowing in deeply and then extricating his group whilst leaving some cutting aji. Then in the endgame Ke won when he killed that formerly thick group which didn't actually have 2 eyes after refusing to be bullied into a passive life. Also Iyama (white) played an AG-style early 3-3 invasion and played the 4th corner as a 3-3 in a cross fuseki. This reminded me of his first game with Ichiriki Ryo in the Tengen title match in which in which he as black invaded Ichiriki's 4th corner 4-4 at 3-3 for move 5 and seemed to get a good result in the resulting joseki and subsequent ladder breaker fight. I predict in their semi-final game we will see no 4-4 points. |

Both the quarter-finals and semi-finals are being played in the Nihon Ki-in. Brilliant piece of prediction by the scheduler given that no Koreans will appear in the semi-finals! Anyway, home turf may help Iyama. |

Sina analysis seems happy that Korean pro didn't make into semi final.  https://sports.sina.cn/others/qipai/201 ... 762.d.html I really cheer Iyama because he's the solid proof that Japan doesn't fall behind the international go competition but some Redditter told me that we shouldn't count Iyama because he's the 'anamoly' of Japanese professional system. |

Could you elaborate which group is killed at the end? Perhaps I misread something, but I think the black group is alive if he capture the single stone on the 2nd line. The lower center group surrounding by White also seems alive to me, or is it dead instead? |

The lower center group surrounding by White also seems alive to me, or is it dead instead? If Shin lives with the one in the bottom right then Ke kills the bottom middle with bulky five: If 4 is at 5 then then W atari at 4 and although black captures 4 stones in L shape white recaptures and it's dead 3 eyespace. The two square marked stones are the ones which enabled this sneaky kill. The centre one was tenukid for and endgame move at top left, the lower one was answered at 1st line in bottom left: attempting to get double sente yose. If the latter was answered with living with either group to prevent the double attack I presume Ke planned to play the bottom left 1st line in sente and then maybe complete the lower side territory at a. Whether Shin saw this kill but realised living left him behind on points so played his squared stone as finding a place to resign, or it was an oversight I can't say. P.S Thanks to macelee for quick upload to go4go for the diagram. |

I've only done a quick replay of the games rather than any in-depth study, but here's a puzzle: why did Yang allow Iyama to push through and capture the cutting stones instead of connecting with a bamboo joint at a instead of 1? the 2-5 exchanges seem to just about make the push through and subsequent net work, so did Yang miss this, or consider they were lossy enough he could give up the cutting stones and get sente for b? (Also black played f12 so I suppose there's more bad things white can do there than I assumed at first glance). That he resigned on move 126 after just some minor skirmishes at the bottom left and then 2 moves bottom right suggests things didn't go as he planned. |

A possible factor was time. I don't know whether he was in time trouble (the main setting was a decent 3 hours each) but, if he was, byoyomi was just 40 seconds, which seems to have become the norm in Korean events. |

That Redditter would be correct. If Japan weren't behind Korea or China, then you'd see more Japanese players in the semi-finals and finals of international events far more frequently. When was the last time a native Japanese player made it this far in an international event? |

Before that, believe it's Yoda Norimoto in the same event in 2007. This suddenly reminded me of Nongshim Cup, and I do miss its glorious 3-year stretch from 2003-2006, when the three nations went back and forth and fought all the way to the end every time, punctuated by Yoda Norimoto ending Lee Changho's unbeaten streak to win Japan's only title. |

Anyway, he's sitting at world ranked no.3 right now and I'll watch this ranking happily all day cause it might change (for worse) after tomorrow's result comes. One more interesting, Cho Chikun was the commentator in yesterday so I'm wondering that he's the commentator for all big events because he's funny? I'll watch relay game from go server tomorrow but would love to see the game live if it broadcast anywhere! |

While you're being polite enough, this topic is sufficiently contentious that we have a dedicated thread for arguing about it: viewtopic.php?f=13&t=13750. That was mostly because of a particular troll who is long gone, but it seems like a good policy. |

Game Ke Jie/Iyama. Ke Jie indeed goes for 2 san-san, but Iyama does play a 4-4 and even decides to take the outside with the high Chinese fuseki. Ke Jie's move 22 also seems to be inspired by what Fan Hui showed him in the review of his games with Alpha Go. Now I think the outcome depends on how good B can attack the W group. The lower side also seems to have some bad aji. I would say the game is a bit better for Ke Jie at the time  .
