Semi-final results:

- Choi Jeong beat Li He by resign. I wasn't a fan of Li's play on the lower side / tengen (if I was reviewing a weaker player's game I'd say "just because there's a dot there doesn't mean it's a good move"), and Leela Zero (#128, 2k visits) agrees Choi pulled ahead here, and even more so when Li obediently followed her funky knight's move 'joseki' at top right.
- Kim Chaeyoung beat Yu Zhiying by 1.5.

Black answered 1 with the knight's move (to prevent press one space up), but LZ is not a fan, it wants to kick at a and treat right side pincer stone lightly. I remember at the Amateur gold cup in China Ma Tianfeng 7d (top Chinese amateur) got a good result against one of the European 6/7ds there with this knight's move, and kick as best answer was the conclusion of our analysis (but in that game black's left side was more important so Ma's move was probably very good). LZ also says 4 is a wimp, must cut or at least get bigger corner, and slide too (attach and crosscut, but by then down to 38%).

So final is Korean #1 vs #2, Choi leads 4-0 head to head (with 2 from 2018 female Kuksu title match earlier this year), but Kim is improving, can she step up her game on the big stage?

[macelee]

I think Kim played a fine game today. She and her sister have improved so much recently.

[xiayun]

Kim Cheayoung won Game 1 of the final over Choi by resign.

Kim won the 2nd game by 5.5. Choi played some pretty wacky centre moves, and then this 2 here I really don't understand. Yeah the ladder isn't good, but surely basic cut/connection principles say you need a darned good reason not to cut and let black get the connection? It's not like the 2 got anything amazing or even a contact move with a strong follow-up. I suppose it did help with the n5 attach/cut later so Kim just tenukid that. Maybe p12 is small/light as it already got black to answer at r14, but black is not so sad to have played there as it reinforces the corner (white did manage to live there later due to some helping aji on outside).

I asked LeelaZero, she preferred 2 at 3 but said 2 wasn't so terrible, just -6% (which I think pros can be disappointed about but isn't rare). Biggest mistake so far was d12 cut which allowed black to live on side in sente, prefers d13 shape poke by 8%.

Can anyone help me identify the European players of this year's Go Seigen Cup World Women's Championship?

From their names translated to Chinese, I can recognise some of them. But is this player involved: http://www.europeangodatabase.eu/EGD/Pl ... y=15774187

In the 1st picture of this article, I think I can pretty clearly recognise Ariane Ougier on the right side: http://sports.sina.com.cn/go/2019-04-26 ... 5140.shtml Does that help...?

Is someone else from Europe there, too?

And: Is there an official website?

[jlt]

If there are three European players, logically they should be Natalya Kovaleva, Ariane Ougier and Rita Pocsai who were on the podium of the European Women's Go Championship 2018

http://www.europeangodatabase.eu/EGD/To ... n=10686346

Edit: since there are 8 players from Europe and North America, maybe there are 4 from Europe and 4 from America?

[macelee]

You are right. The 4th placed player in that EU tournament is also playing in this international tournament.

[Mapleleaf]

Yes there are 4 players from Europe and 4 from North America. They played each other for the first round:

Stephanie Yin Vs Cathy Li
Ariane Ougier Vs Rita Pocsai
Gabriel Su Vs Natalia Kovaleva
Feng Yun Vs Dina Burdakova

The next round will be tomorrow:

Hsieh Yimin Vs Gao Xing
Mannami Nao Vs Wang Shuang
Feng Yun Vs Lu Minquan
Nyu Eiko Vs Li He
Ariane Ougier Vs Yang Zixuan
Kim Hyeoimin Vs Natalia Kovaleva
Oh Yujin Vs Stephanie Yin
Cho Seungah Vs Yu Lijun

Yu Zhiying, Rui Naiwei, Wang Chenxing, Kim Cheayoung, Choi Jeong, Oh Jeonga, Ueno Asami, Fujisawa Rina will play in the next round I believe.

I think I would cheer for Oh Yujin this time for her aggressive playing style, although Yu Zhiying and Choi Jeong are favorites for this tournament.
