Ke Jie is very sad according to his social media post.

By the way, the final stage is rumored to be in China, but that may be due to Google mistranslation

Up and following the first game of the final.

Is the variation in the lower right (

) a relatively recently played move or am I just truly clueless about joseki?

Here is the gogameguru report on Xie 5p's wins over Rui Naiwei 9p and Yamahita Keigo 9p when he was 13 years old 6 years ago

https://gogameguru.com/13-year-old-xie- ... iling-cup/

And commentary of his win over Li Kang 6p in the same tournament

https://gogameguru.com/go-commentary-xi ... iling-cup/

So it is definitely a pleasant surprise to see him in an international final after all these years, but the fact that it is also Iyama 9p's (and Japan's) chance to win an international tournament after all these years makes it a doubly exiting matchup, if also a somewhat unfortunate coincidence.

Elom, lower right is a new joseki drom AlphaGo. Also top left you shifted one line. White's push on 2nd line there rather than connect may also be influenced by AlphaGo (but does pre-date AG): in 4-4 pincer and take corner josekis it often prefers that crawl to connection.

Thank you, diagram corrected!

I see about the joseki in the lower left, it does seem an interesting variation. Similarly with the top left— both suspicions happened to be correct I guess.

Elom, your diagram top left was still a line off horizontally, I used my magical admin powers to fix it.

As for the game, sgf below courtesy of go4go, my summary based on 4d ama feeling would be:
- top left because black tenukid for 19 and W could close (in effectively sente as B came back to add move at 41) I prefer W's crawl to usual joseki where b pushes down there, even though B got to double approach.
- I've never been a fan of 45.
- ladder breaker of 61 was key moment. That white fixed left and didn't die on top seems like fail for black to me.
- sequence to 94 seemed locally awful for black to me, only good thing is black got sente twice. Maybe left stones aren't so big?? But w got centre power too
- which he used to split white at 101 and got a nice attack
- that centre power meant 130 was strong, b's wall was weak
- B nicely managed to live to 157
- ending sequence seems like B messed up somewhere (167?), dunno who was ahead if b keeps side and middle survives with w getting reductions and probably slide top right is tedomari. Maybe white so 167 was seppuku?

Iyama won (a complex) game 2 by half a point so we get a decider. Hooray!

p.s. This game is amazing, great amashi and fighting from Iyama.

In the first game, Iyama 9p was ahead earlier on, but faltered towards the end.

Iyama 9p was present 15 minutes before the start of the second game.

Two minutes to the start, Xie 5p arrives.

And before one could tell, a complicated fighting match was underway (I was in no state to follow this kind of match at the time I was up and was becoming dizzier with each move)

At the very least Iyama sensei's sensei, who trained Iyama 9p on countless training games online, was present for the match.

They say the half point is in God's hands, and if anyone has been on losing side of half-point games on the international stage, it would be Iyama 9p, with at least one due to a slip from a lack of familiarity with play by chinese rules.

And it seems that either by being in Japan or having his teacher to watch, fortune has changed sides for Iyama 9p in what could only have been an unimaginably difficult match (you will never complain about go your go games again after seeing what an actually difficult ~~game~~ match looks like...) and he managed to win by half a point.

We may never know if Xie Erhao received a reward for his wonderful performance at his first major international tournament six years ago, but I think we might be seeing him more often anyways, win or lose the third game is currently underway.

P.S. Even though Iyama 9p is in a position for a reverse swoop, I do think Xie is still slightly more likely to win...

you will never complain about go again after seeing what a actually difficult game is...

We're so lucky to be alive to witness a level (AZ's) significantly beyond top human understanding ( and it's only a beginning ).

it's worse than that; i've heard that there are mad scientists planning to build machines that can run faster than me, fly higher than me, swim deeper than me, pull heavier ploughs than me, do sums better than me, see things i can't see (like radio waves), and never have to go to the dentist,...

after black 19, i expected white to push through, which he did... at move 74!
are these people human??!

what's for breakfast?

Posted: **Wed Feb 07, 2018 11:04 pm**

so sad right now, why Iyama Yuta never win at international level.
Hope he can win at World Go Championship

I've just realized I sound like I'm referring to go itself.
