BadukPop app adds AI opponent

Friday May 22, 2020

BadukPop has added several improvements in its latest update, including the ability to play against artificial intelligence. The popular go problem app, developed by Hajin Lee 4P and Dan Maas, works on both Android and iOS. The interface was designed to be fun for all ages, including kids, and now features 7 humorous AI characters you can play against. The weakest is Bobby – perfect for people who have just learned to play. Next up is Kevin whose “mind wanders off into deep space – and so do his go moves.” As players work their way up, the AI gets much stronger. “I love playing against Cora,” says Lee “she’s my new rival – I have about a 50/50 win rate against her, and it’s really fun to have a quick game with her now and then.” At the top is Max “a powerful AI that plays at human professional level.”

The app only supports games on 9×9 for now, but 13×13 and 19×19 are coming soon says Maas. A new section of lessons has been added as well. Designed as short sequences to teach new players, you can go from learning the rules to mastering basic corner and side positions. Like everything in BadukPop, the lessons are designed to be quick so one can learn something in just a few minutes, but build deep knowledge over time. Lee goes over the new features on her Youtube channel here. The app is free, but has in app purchases for extra features. Download from the Apple or Android stores, or from BadukPop’s website here. -Paul Barchilon, EJ Youth Editor

To call it shocking would be an understatement.” Tune in tonight at 7p, when viewers will be able to ask Redmond and Garlock questions during the live commentary.

AlphaGo vs. AlphaGo; Game 40: It gets weird in the endgame

Friday May 15, 2020

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 40th game of the amazing AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over world champion Ke Jie 9p in May 2017.

Originally broadcast live on the AGA’s Twitch channel on April 5, in the early days of the COVID-19 pandemic, Michael and Chris begin by checking in on the status of the professional go community in Japan, and they also talk about Michael’s YouTube channel, which he had just launched.

“In this game, AlphaGo is going to look a bit like two human players,” Michael says. The game starts with the mini-Chinese opening and the rest of the game “looks like a game two human players would play, but then it gets weird in the endgame.”

Michael Redmond 9p, hosted by the AGA E-Journal’s Chris Garlock, reviews the 39th game of the AlphaGo vs. AlphaGo selfplay games. The 50-game series was published by Deepmind after AlphaGo’s victory over world champion Ke Jie 9p in May 2017. Chris and Michael chat about Redmond’s new YouTube channel and catch up on how Japanese pros are dealing with the COVID19 shutdown. “In this game, you’re going to be surprised a few times, when AlphaGo plays away from a position,” says Redmond, “plus there’s the usual stuff that it does with ladders. AlphaGo has special ways that it deals with ladders, which is something that’s caught on with human players.”

How AI study helped improve my go

Wednesday March 25, 2020

by Benjamin Teuber 6d (Germany)

For many years, I was considered the “eternal second” of the German championship. I finished as runner-up nine times – while never winning the title. No matter how well I did, I always managed to lose the decisive game.

Until November of last year, when, to my own and everyone else’s big surprise, I finally became German Champion with a perfect 7-0 record. After the tournament, I got a lot of comments like “you clearly improved” or “you must have studied a lot” from people. But, to be honest, I didn’t prepare much for this tournament. I did no go problems at all, I didn’t play many tournaments, I didn’t take any pro lessons. Please don’t get me wrong, I highly recommend these measures and have used them a lot in the past; that’s how I became 6 Dan, after all. They just can’t be responsible for my recent improvement.

What I have been doing though, was creating my own go study website, ai-sensei.com. It allows you to upload your games and quickly get them analyzed by very strong AI. I believe the key feature of this tool is the focus on big mistakes; that way you can work on your biggest weaknesses instead of getting lost in minor details. So while I didn’t spend as much time studying as I had previously, I did use AI Sensei to review every one of my games and find my biggest mistakes. I would also check an old game every now and then to review my past mistakes. Looking back, I believe this was a very efficient way to spend the limited time I had to study, and it might well be the biggest factor of my recent improvements.

So here’s my advice to anyone using go AI to study:
Focus on your biggest mistakes in each game
Don’t waste time exploring all the variations
Think about the AI recommendations in terms of shape, direction, and strength of groups
Revisit your past mistakes

I invite you to try out AI Sensei yourself; it can be used for free. But whatever tool or AI you are using, I think you’ll find these recommendations useful.

AlphaGo vs. AlphaGo; Game 37: Into thin air

Sunday March 22, 2020

In this game, “the attacking side suddenly abandons the attack and sacrifices some stones,” says Michael Redmond 9P in his latest AlphaGo game commentary with Chris Garlock. “The attack sort of disappears into thin air.” At the same time, the defending side is trying to sacrifice some stones as well, “so it’s a very unusual fight,” Redmond says, “it wouldn’t happen among human players, I don’t think.” Oh, “And the endgame gets a bit exciting, too.”

The commentary originally streamed live on the AGA’s Twitch channel; follow it to get notified of upcoming live streams.
