I watched the AGA, Kim Myungwan considers that B is slightly ahead before the sequence (after moves 150), and to him Zen already had no more than 10% chance to win at the moment. He also evaluated the sequence a bit after Zen had resigned, and he seems to agree that the sequence "B profits and takes sente, while W lives" is the best sequence for both, thus Zen resignation didn't really surprise him.

Interesting to know that it actually causes Iyama and the Chinese top pros some headache . Does anyone have their final conclusion of the board?

It seems that if the computer is playing then for a human to resign would be against the rules.

From Japan Times

“I felt as if I was playing with a human, because (DeepZenGo) has both strong and weak points,” Cho said after the final game.

DeepZenGo “suffered a crushing defeat today,” developer Hideki Kato, 62, said. But he added: “I know exactly what needs to be fixed.”

(And interesting that v13.1 is already testing, Yoji Ojima is very hard worker.)

Thanks a lot, pookpooi!

Here’s the link to the article in the Japan Times you mentioned.

Funny how the Japan Times article makes the same mistake as xhu98's graphics for the AGA stream saying Cho has "only" 74 titles when he now has at least 83. I figured the source for that might be the English wikipedia article (which is largely a copy-paste of an old version of the sensei's library article, which itself is largely sourced from Dutch Cho Chikun fan Jan van Rongen: http://rongen17.home.xs4all.nl/Cho/index.html) but that says 73. I wonder where it comes from. I suppose you could discount pair go titles like the Ricoh Pair Go Cup (3 times) or the veterans' Igo Masters cup (3 times) but that still gives him more than 73 (which was the correct figure in 2003 when SL was most active and did include Hayago titles).

On a related note: https://xkcd.com/978/

I guess the 74 titles is the official count by the Nihon Ki-in and the extra titles don't pass some arbitrary criteria. See http://www.nihonkiin.or.jp/player/htm/ki000004.html

Yeah, they used 74 titles in the japanese commentary as well.

Also, a bit more info regarding the resign:

The winrate on the stream showed 60%. However, Zen's actual winrate was 50.1%, and in reality, that means less than 40% because Zen is overly optimistic. Hideki has been tweaking and making zen reevaluating the whole game, and after seeing how Zen's winrate was continuously dropping and playing bad moves, he decided to resign for Zen.

Ke Jie and Tang Weixing both played out sequences to show that Zen had no chance, with Ke Jie saying something like "Zen's resign was not wrong. In fact, it was the most brilliant move Zen played in these 3 games, since it demonstrated considerable reading."

ZenAuthor said Zen v.13.0 for the first two games and v.13.1 for the third game. (13.1 is a little bit stronger than 13.0)

Could you expand on this? If Hideki was giving human input to Zen while the game was going on, then it seems wrong to call the match "Cho vs Zen"!
