Cho is also a good choice for his sabaki inside moyo skills: when Zen has some big moyo on KGS I will sometimes kibitz "someone call Cho Chikun", and now they did! I think the recent neural net Zen might not be as extreme moyo style as it used to be though. Looking forward to the match, do we know broadcast details?

There's rule in pdf file in that website, I poorly translated it by Google and all I get is that there'll be game 3 even if two previous games are won by one side.

It was only in March this year that Zen played Kobayashi Koichi on 3 stones, and won by 4.5 points, see viewtopic.php?f=18&t=12906.

This will be fun! I hope playing against an AI doesn't prevent Cho from slamming down a stone or two! :D

I wanna know when will we have the chess engine equivalent of go software.

Like droidfish that is based of stockfish 8 can be downloaded on androids and on a current hardware it is at GM level if not stronger.

I love Cho Chikun. I would also like more commentaries from Cho with English subtitles. Great news for Zenith Go, will there be a new commercial version of Zen soon?

Crazy and Zen are playing on grandmaster level already. 6 Dan is around 2600 Elo.

I want my Cho Chikun deep learning edition of Zen Go now! :-)

You're not missing much. It's mostly about regulations to do with handling the computer side, e.g. the computer will use its own internal clock, the handler will have extra time to make the moves physically; the human will use a chess clock) and possible disputes. Games 1 and 3 will feature nigiri and the ruleset will be Japanese (can Zen really cope with that?).

The fact that they have set out such a protocol gives an impression that this is being taken very seriously. But I see that Magnus Carlsen has apparently called in Microsoft for help in preventing Russian hackers finding out what opening preparation he has on his computer, so this will presumably be the way of things for go in the future.

Cho has been in reasonable form lately, only just missing out on another title, and is not normally the blundering type, and I imagine he's also been able to study some Zen games. But my sense of what is going on here is that Japan may be hoping to recover a little bit of national pride by having the first oriental program to do well against pros, so maybe a lot of people will be rooting for Zen in Japan.

To some extent he's actually already part of Zen6, which is the deep learning edition of Zen. Although I'm guessing the v12 Zen engine (as used in Zen19X) uses a value net in addition to the policy net the v11 engine in Zen6 has implemented at least.


Take a look at the cover: https://book.mynavi.jp/ec/products/detail/id=62646

The hardware costs at least $15,000 (from that CPU+GPU+Ram info) and is the most powerful machine that Zen would ever use, comparable to the single machine version of AlphaGo. I don't know if AGA is also planning to livestream with English commentaries but I hope this time Michael Redmond would be a nice choice.

A Japanese article: http://pc.watch.impress.co.jp/docs/news/1029075.html

From google translate and looking at graphs, I think:
v11.4 is rated 2400
v12.4 is rated 3000 -- they mention this is the same as Fan Hui's rating.
These ratings are on the goratings.org scale, I don't know how they calculated the numbers.
The article doesn't mention it but on CGOS Zen-12.7-1c0g is about 120 rating points higher than Zen-12.4n-1c0g

They also show a graph of Zen's rating on KGS jumping from 7d to 10d.

ETA some more goratings:
Cho Chikun 3238
Lee Sedol 3507
Ke Jie 3623

Just saw news in English, this is the part I like
“I saw its (DeepZenGo’s) records and it’s very strong,” Cho said. “I was kind of bored with playing Go with humans, and I’m excited to play a match with a computer.”
Will Zen has its place in goratings.org as well?

"Very strong"="Stronger than me"
That's how I read it, coming from someone like record title winner Cho Chikun.
