AlphaGo vs. AlphaGo; Game 30: “The black player would be upset, white would be happy, and they would both be wrong.”

Thursday April 11, 2019

After a nearly 1-month hiatus, Michael Redmond 9p and the AGA E-Journal’s Chris Garlock returned last Friday with the latest 2019.04.05 AG30 in their series of video commentaries on the AlphaGo vs. AlphaGo selfplay games. “This is the one 2019.04.05 AG30-redmond-garlockgame in this series in which AlphaGo plays a variation of the taisha,” says Redmond, “and it reminds me of a variation played in the ‘ear-reddening game’ played by Shusaku against Gennan Inseki in 1846.” “Mindblowing stuff!” says GerSHAK.

The Power Report: Honinbo League ends in three-way tie; playoff April 10

Tuesday April 9, 2019

by John Power, Japan Correspondent

Honinbo League ends in three-way tie; playoff April 10: The big news is that there’s a three-way tie in the Honinbo League and the deciding game will be played on April 10; I’ll report the result as soon as I hear it. Here’s the result of the last game in the sixth round. On March 21, Kono Rin 9P (B) beat Yamashita Keigo 9P by resig. This was Yamashita’s third loss, so 2019.04.09 Honinbo leagueit put him out of the running to win the league.

The final round of the 74th Honinbo League was played at the Nihon Ki-in in Tokyo on April 4. Following the lead of the Meijin League, all the games in this round were played on the same day. As this round started, four of the eight members of the league were still in the running to become the challenger: Hane Naoki 9P, on 5-1, and three players on 4-1, Kono Rin 9P, Ichiriki Ryo 8P, and Shibano Toramaru 7P. If he won, Hane would clinch the challengership, but if he lost there would a play-off: Kono and Ichiriki were playing each other, so there would be a least one other player on 5-2.

The results:
Yamashita Keigo (B) beat Hane by resig.
Shibano (W) beat Ko Iso by resig.
Kono (W) beat Ichiriki by 1.5 points.
Yo Seiki 8P (W) beat Anzai Nobuaki 7P by resig.

The result was that Shibano, Hane, and Kono ended in a tie and qualified for the play-off. Usually only the two higher-ranked players in a multiple tie make the play-off, but Hane and Kono had the same rank. They played each other on April 8, with Kono (B) winning by resignation. Hane either had the sole lead or shared the lead nearly all the way in the league, but he stumbled at the end. Kono’s win continues his superb form: his record this year is 13-1.

Kono will now play Shibano on April 10. The latter was seeded into the second stage of the play-off because of his higher ranking in the league. At the other end of the league, there are no play-offs for retaining your place. Yamashita, Yo, and Ichiriki all finished on 4-3, but Yamashita’s number one ranking gave him priority over the other two. This was a tough result for Ichiriki: one game made the difference between tying for first and losing his place in the league.

EGF takes lead in Transatlantic Pro Team championship

Sunday April 7, 2019

Mateusz Surma 2P from the European Go Federation (EGF) defeated Andy Liu 1P in the first round of the 2019 Transatlantic Professional Go Team Championship on Sunday, April 7. The game was played live and broadcast by the AGA on Twitch with host Nick Sibicky and commentator Eric Lui 1P. More than 12,000 viewers observed the nail-biting game that lasted more than three hours.

In early mid-game, Surma’s mis-steps in the upper right corner led to Liu’s advantage, building strong shape in the center. However, Surma persisted, collecting points on both the right and left sides, and perfectly timing a deep invasion into Liu’s territory on the lower side. The invasion led to a complex fight when both players were in byoyomi. A series of ko fights created huge exchanges that were much favorable for Surma, and Liu resigned.

The AGA’s next player will be Calvin Sun 1P, and Surma will be playing with Black in the next round, scheduled for April 14, 14:00 EDT on KGS in the Transatlantic Pro Team room, and broadcast live on Twitch. All videos of the live streaming will also be available on YouTube.

Laoshi Zhou and the southern part of heaven

Monday April 1, 2019

by Bob Bacon2019.04.01 Yuan Zhou NC workshop

Raleigh, North Carolina is often called the southern part of heaven.  We’re blessed with a comfortable climate, beautiful natural scenery, honest hard-working natives, outstanding universities, progressive businesses, lots of wonderful immigrants, healthcare workers, scientists, writers, and a sprinkling of Go players.  We’re also fortunate to be within traveling range of Maryland based Yuan Zhou, one of the nation’s leading Go teachers. Laoshi (teacher) Zhou conducted another of his invaluable workshops for us last weekend, and attendees were happily educated in this finest of arts.

In addition to the usual game reviews, which were very beneficial in themselves, teacher Zhou presented two lectures on games from the recently concluded 2019 LG Cup.  Describing the young players Yang Dingxin and Shi Yue as “Dragon 2019.04.01 Yuan Zhou NC workshop2Hunter” and “Tank Driver” helped us understand the styles of play each player employed, and some of the deeper foundations of the game.  Both games were very interesting and shifu Zhou’s explanations were enlightening.

Laoshi Zhou provided much helpful advice throughout the workshop, often presenting concepts in the guise of folk stories, making them easier to remember, such as the bear and the cornfield, and dragon lover Gong Ye.

Yuan Zhou also provided an very helpful review of the 3 3 point invasion, explaining the benefits, consequences and history of this trendy move.  A prolific Go author, laoshi Zhou has written a number of books on Alpha Go, Go Seigen and the 3 3 invasion, published by Slate and Shell.

We were taught much, learned as much as we could, ate well, slept just enough and enjoyed the modern meeting facility arranged by Dale Blann, one of our club members.  I can’t wait until we do it again!

Monday April 1, 2019

The Seattle Go Center is pivoting to teaching the science of playing Go, instead of the art of Go playing, according to Program Manager Mike Malveaux.  Lab coat with Mike Malveaux sq crop copy“Our latest class, held on Wednesdays, is on programming computers in Python with Artificial Intelligence / Machine Learning techniques, loosely following Deep Learning and the Game of Go by Max Pumperla and Kevin Ferguson.”  Operations Manager Brian Allen notes that some of the Go Center instructors have impressive scientific credentials.  For example, Yue Zhang has a Phd in Paleontology, in addition to being a 7 dan Go player. Lab Coat with Display Board sq crop copy To emphasize their connection to science, all teachers will be required to wear lab coats with Seattle Go Center logo patches.  “In the age of AlphaGo and Leela, our members expect this,” he reports.
