Re: Following Iyama Yuta (no world ranking discussions)
Iyama has an early lead but from his style I predict the game will come close again until nearly the end.
Some interesting point, ever since he became the youngest Meijin and youngest 9P ever in Japan in October 2009 his Elo has been highest among Japanese pro, supassing Cho U at that time. And I estimate it'll continue to 2020. (It's ok if talking about domestic ranking, not world ranking right?)

Re: Following Iyama Yuta (no world ranking discussions)
Turn out there is no middle close game this time as Iyama Yuta leading further and further. Fox server has relay this game (I'm wondering how Fox can relay so many important matches) and right now FineArt bet 91.6% on white
Latest update: Iyama Yuta wins

Re: Following Iyama Yuta (no world ranking discussions)
Any thoughts/reflections from stronger players on the recent Pair GO Match : Yu Zhiying & Ke Jie Pair
Black: Hsieh Yi Min & Iyama Yuta Pair: played. I have gotten about halfway thru the M. Redmond review, and it is an exciting game. I admit I was rooting for Iyama and Hsieh. I think a win would be a shot in the arm for Japanese GO.

Re: Following Iyama Yuta (no world ranking discussions)
Today, Iyama beat Yang Dingxin of China and advanced to the semifinal of the LG Cup. The game is given below. His next opponent will be Ke Jie. I'm not sure when the game will be played. In a bad translation of a Japanese tweet I read something about Wednesday - can somebody confirm that?

Re: Following Iyama Yuta (no world ranking discussions)
I wonder if somebody could break down the reasons for the early resignation in this game?Ember wrote:Today, Iyama beat Yang Dingxin of China and advanced to the semifinal of the LG Cup. The game is given below.
What I do think I understand is that Black violently set out to kill something and failed. As a result, Black lives small on the top and White is likely to get a lot of of territory at the bottom. Black might not be able to resist at the bottom because his O6 group still has to bother about making two eyes. On top of that, Black probably can't expect a lot of points on the left side because White has already spilled in.
So from my limited understanding, Black went all out and ended up strategically busted? Is this roughly what happened here? It still strikes me as early but what do I know...

Re: Following Iyama Yuta (no world ranking discussions)
It is a weird game, I was surprised Yang just gave up the key cutting stones in the centre fight. I've got more questions (see forum/viewtopic.php?p=225051#p225051) than answers, but here's some preliminary analysis. If not for the resign, perhaps the game would continue like so. It's painful to answer but I think 3/5 are probably sente or black's right side group is going to end up tiny in sente (actually maybe not if black has a to capture the 2 marked stones?).Revilo wrote: So from my limited understanding, Black went all out and ended up strategically busted?

Anyway, if white can get those exchanges in that's a bonus, but probably then with the exchange of 1 for 2 white has fixed the bad aji in the bottom that he could descend and make a large lower side if black can't live inside? Let's say white isn't scared of ko.
Can black resist and live inside? If it weren't for the 1-2 exchange probably 8 was sente, but now it's not so a kill looks more plausible. This still looks like a sufficiently difficult life and death problem that you could play it out before resigning though.
As for the left side, black's not going to make much there, some extension on the side around a above and connecting/cutting the 2 stones at b are kind of miai (and if black a white b then there's still some problem at c).
So if I try to simplify the game to get a countable position I might get something like this with the following caveats: 5-6 a bit generous to white, 7 based on premise black can't live inside.
14 could be overplay as black might fight ko, but actually as capture at 16 is sente it wasn't so important to get 11 atari and could just 13 as seems 2 centre stones still can't escape. Because of the cut of 16 black could fight more instead of making left territory with 18, but just for sake of argument let's say he cashes the aji to close the territory and white is obedient... Also white answering 22 at 23 is maybe passive, and maybe black would hane and live in the corner but then the left side is damaged and I don't want to count that.
So counting this position, white has:
- lower side: 33
- middle: 9
- top left: 16 (hmm h18 semedori?)
- top right: 11
- komi: 6.5
Total: 75.5
Black has:
- bottom left: 13
- top right: 9
- right: 6? + if gets m10 12ish (loses a bit at k11) so count as 6 + 12/2 = 12 total
- middle: 13
- left: 25
Total: 72
So my example early endgame and count gets a white lead of 3.5, which is big in pro games, but small considering how much game is left and I'd say my playout could have an error of 5-10 points, particularly as Iyama might destroy the left side more aggressively and perhaps could apply more pressure to the right side group, perhaps finding a way to save the 2 stones in sente. Then again black also has options to be more enterprising. So not resignable at my level, I suspect Yang was psychologically beaten with his fighting plans going awry as much as on the board.
P.S. I wondered here should black have exchanged 2-3 after 1 before extending at 4 to prevent white's break through at a in the game? Maybe white would ignore and sacrifice the tail? Update: some analysis by strong bots at forum/viewtopic.php?p=225087#p225087

Re: Following Iyama Yuta (no world ranking discussions)
I had a lot of fun analyzing Iyama vs Ke, very good training material for the upcoming tournament in my country. Using the help of DeepZen, I noticed that Ke and Iyama were very much equal throughout the game, but after the big fight on the right side, B (Iyama) was winning. A lot. Seems to me that W (Ke) could've tricked B in the endgame. Anyone have thoughts on this particular position? Or some thoughts on the game?
