This will be a good opportunity to see the EGF and AGA pros playing some top Asian pros. Anyone know broadcast details? I'm guessing they'll be on Fox/Yike.

From https://www.intergofed.org/igf-news-fee ... rules.html

China: Ke Jie, Mi Yuting, Gu Zihao, Yu Zhiying, Wang Chenxing
Japan: Murakawa Daisuke, Ida Atsushi, Motoki Katsuya, Mukai Chikai, Nyu Eiko
Korea: Shin Jinseo, Lee Ji Hyun, Park Jeong Hwan, Choi Jeong, Oh Yujin
Chinese Taipei: Yuan-Jyun Wang, Li-Hsiang Lin, Hao-Hung Hsu, Joanne Missingham, Hsin-Hui Pai
Europe: Ilya Shikshin, Pavol Lisy, Mateusz Surma, Natalia Kovaleva, Ariane Ougier
North America: Ryan Li, William Shi, Eric Lui, Xuefen Lin, Gabriella Su

(Followers of the Transatlantic team timeout drama will note the opportunity for an Eric vs Mateusz rematch. Also the players/organisers will discuss that case in person there).

My predictions:

Men team:
1. China
2. Korea (but hard to call vs China, maybe Shin and Park can carry them)
3. Taiwan
4. Japan
5. Europe
6. North America

Women team:
1. Korea
2. China
3. Taiwan
4. Japan
5. North America
6. Europe

3 and 4 close for men and women, Japan not sending their best otherwise they'd be 3.

I see the schedules are as below: https://home.yikeweiqi.com/#/gonews/detail/25031?type=1

Morning game starts at 9:30 and afternoon starts at 14:00.

I don't think a Mateusz Vs Eric game will happen as Mateusz is Board 1 while Eric is in Broad 3. Europe plays North America in the 3rd round (May 15, 9:30am), Mateusz vs Ryan, Ilya vs Gansheng, Pavol vs Eric.

PS. Mateusz is in a losing position against Park, but Ryan is slightly leading (black 67%) against Murakawa when I'm watching on Fox Go at the moment.

Here's the game Surma (white) vs Park. They had one of those complicated modern 3-3 invasion josekis which turned into a big fight which Park won. Variations are from FineArt (Jueyi) on Fox and me with LZ. Highlights:
- a14 hane should h15 atari in middle, it's ok to not set up seki in corner because even if you die attacking top with l17 is big compensation and black has to watch his libs. f19 should also h15.
- Park's h19 should be d18
- c19 big (-40%) mistake, should be h16
- but Park's h14 almost returns the favour (-26%) as it allows W to almost revent with the pleasing atari. Instead set up corner seki and extend at h15 to make nice eyeshape. FineArt agrees.
- Surma j15 overplay. He presumably wanted black to directly atari without pushing once, so when black tried to improve on that resisted, but submitting was wiser. h12 turn still decent after.
- k15 mistake is an interesting shape lesson I've seen before. Locally the move you want is j16 comedy empty triangle because it sets up the snapback shortage of libs at h17 which gives black a problem in taking a liberty for the corner semeai. LZ says best order is to probe first in corner, black ignores to capture outside 2 stones but their aji means white has effectively captured the corner because if he tries to make the seki then white breaks out k16.
- r17 3-3 greedy as gote, centre fight balance of power bigger
- d11 wrong shape, but it's hard fighting anyway and Park goes for the jugular.

Unfortunately Ryan Li lost to Murukawa Daisuke. The opening was a little bad for him but he took the lead from middlegame fighting on right and impressively held onto it for a while. However, bad aji of the 2 stones was too much, m9 was an overplay trying to keep everything and Murakawa seized his chance to make miai and punish him.

Uberdude: thanks for keeping us up to date. i'd only suggest using full names - i think it is nicer to read and in the first round you mixed some first and last names
Spilling gasoline feels good.

I might be wrong, but probably not.

It's nice that Mateusz was put on board 1, presumably as reward for his Transatlantic performance, and gets to play Ke Jie and Park Junghwan. Getting to play Mi Yuting or Gu Zihao is not bad either of course.

Standings so far are:
Men:
1. China 4W 0L
2. Korea 3W 1L
3. Japan 2W 2L
4. Taiwan 2W 2L
5. Europe 1W 3L
5. NA 0W 4L

Tomorrow is China vs Europe, Japan vs Taiwan (3rd/4th decider), Korea vs NA.

Fun move from Mateusz. LZ thinks it's no worse than Ke Jie's kick top left, but he's already fallen to 25% in early opening. There's so many levels in Go...
