"Group A
Chen Yaoye vs. Shibano Toramaru
Gu Zihao vs. Park Junghwan"

They call group A "Death trap".........

Winners underlined, generally a good round for the Chinese players in the hard to call games, Korean women Choi Jeong bucking the trend with a good win vs Shi Yue. Each group is a double-elimination so not over yet for the losers.

Group A
Chen Yaoye vs. Shibano Toramaru
Gu Zihao vs. Park Junghwan

Group B
Shi Yue vs. Choi Jeong !!
Tao Xinyan vs. Lee Sedol . Lee poor form continues

Group C
Chen Zijian vs. Ahn Kukhyun
Tong Mengcheng vs. Seo Bongsoo

Group D
Ke Jie vs. Wang Yuanjun, same opening Ke played in recent pair go final https://www.youtube.com/watch?v=QnisExRN8J4
Xie Erhao vs. Chang Fukang, but amateur Chang put up a good fight

Group E
Fan Yunruo vs. Na Hyun
Li Xuanhao vs. Shin Minjun

Group F
Lian Xiao vs. Kim Jiseok
Yang Dingxin vs. Lee Youngjoo

Group G
Tan Xiao vs. Yong Seongsik
Tang Weixing vs. Iyama Yuta

Group H
Wu Guangya vs. Shin Jinseo
Li Xiangyu vs. Ryu Shikun

Shibano won an exciting game. Elf says trade for top right was good for black, but black should r7 attach before killing to annoy white shape. Losing move was 153, should o16 peep/connect first, doesn't think white will die but semedori is quite a few points.

One interesting coincidence to note is that Gu Zihao and Park Junghwan were drawn in the same group and played each other in the first game last year too. Gu lost that game before turning it around to win the title, including a revenge against Park in the quarterfinal.

I wonder did Iyama give up too easily? I'm too lazy to count (and it wouldn't be accurate enough anyway), but LZ 157 says its still a close game (he's 42%) and pro games routinely have swings from far bigger margins. Elf v1 unsurpsingly is harsher at 25%, but for example Iyama was 90% by Elf against Cho U and then was losing again later (and then won). Or Shibano was LZ 17% and he won (though that was a more a middlegame position whereas Iyama's going into early endgame).

In a way yes...But it is not uncommon for an old-school Japanese player, something he clearly is, to give up there...Also he might have been under more time pressure viz-a-vis Shibano......

Ke Jie lost to Xie Erhao (advanced to round of 16) and will play Wang Yuanjun again for the other spot from the group.

Gu Zihao beat Chen Yaoye to stay alive and will play Shibano Toramaru next, as Park Junghwan advanced from the group. History is repeating itself there so far. Tang Weixing always plays well at Samsung and advanced, same as Li Xuanhao.

Shi Yue continued his poor form and lost a big group during mid-game against Lee Sedol. Cool to see Ryu Shikun beat Wu Guangya to fight for another day.

And Choi Jeong won again (beating Tao Xinran, #37 at GoRatings), to advance to the round of 16!

And again Choi won from doing better in a ko fight!

There was an interesting life and death corner problem in Shin Jinseo's game today. I added a few sequences, accuracy not guaranteed (edit: improvement for black in the killing sequence? f5 before saving corner stone?).

2nd round results, winners underline, bold won 2 so qualify, strikeout lost 2 so eliminated

Group A (edit: corrected, thanks tryss)
Gu Zihao beat Chen Yaoye
Shibano Toramaru lost to Park Junghwan

Group B
Shi Yue vs Lee Sedol
Tao Xinyan vs Choi Jeong

Group C
Tong Mengcheng vs. Ahn Kukhyun
Chen Zijian vs. Seo Bongsoo

Group D

Wang Yuanjun vs.Chang Fukang,

Group E....
Shin Minjun won by 0.5 vs Na Hyun
Li Xuanhao vs. Fan Yunruo

Group F
Lian Xiao vs. Yang Dingxin
Kim Jiseok vs. Lee Youngjoo

Group G
Tan Xiao vs. Tang Weixing
Yong Seongsik vs. Iyama Yuta

Group H
Li Xiangyu vs. Shin Jinseo
Wu Guangya vs. Ryu Shikun

Are you sure? In theory, the qualified and the eliminated players can't have played together this round. I think this is the correct result :

Group A
Gu Zihao beat Chen Yaoye
Shibano Toramaru lost to Park Junghwan

So, next game is Gu Zihao vs Shibano Toramaru

Third round results:

Lian Xiao vs Kim Jiseok
Ke Jie vs Wang Yuanjuan
Gu Zihao vs Shibano Toramaru
Tao Xinran vs Lee Sedol
Iyama Yuta vs Tan Xiao
Shin Minjun vs Fan Yunruo
Tong Mengcheng vs Chen Zijian
Li Xingyu vs Ryu Shikun

Pairing for round of 16,

Shin Minjun vs Tong Mengcheng
Ahn Kukhyun vs Yang Dingxin
Choi Jeong vs Lian Xiao
Iyama Yuuta vs Li Xuanhao
Tao Xinlan vs Tang Weixing
Shin Jinseo vs Li Xiangyu
Gu Zhihao vs Ke Jie
Park Junghwan vs Xie Erhao

Just reminder.

10/2/18 round of 8

11/5 - 11/7/18 Semi Final(3 games match)

Is Choi Jeong going to reach round of 8? Very tough opponent......

Given the draw, I'm hoping for Choi Jung 9p and Iyama Yuta 9p to win .

Some Elf comments on Xie vs Park



Edit to include UTF8 sgf file as attachment instead of inline to avoid encoding problems.

OK, so his postilion has been struck by lightning - that I can see - but I don't get why White was talking about the Khyber Pass. You can't drive coaches through there, surely? And this is a go forum not a Carry On film, you know.

Pairing for round of 8,

Shin Minjun vs Tang Weixing
Ahn Kukhyun vs Lian Xiao
Iyama Yuuta vs Xie Erhao
Shin Jinseo vs Ke Jie

Here is the game between Ke Jie and Gu Zihao.
Very close game. I look forward to the next round. Shin Jinseo vs Ke Jie will probably very exciting as well
