Saturday, February 16th, 2008
I wrote a brief analysis on this new move:

New joseki

(Link to the article) I saw this move for the first time in the Takemiya Masaki – Yamada Takuji game that I already wrote a blog entry about.

New lesson – “Fighting techniques – kikashi”

Friday, June 22nd, 2007
I wrote a new lesson: “Fighting techniques – kikashi”. It is based on variations on move 33 from the 4th Honinbo game. After introducing some basic sacrifice and kikashi techniques, the main question is how should White respond to Black’s cut with 1 in the following diagram, given that Black’s ideal is to get both A and B in sente:

Black sacrifices a stone to get kikashi on the outside.

“Do you think this exchange is good for you?”

Wednesday, April 25th, 2007

I wrote a new article/lesson titled “Do you think this exchange is good for you?”

It is based on the commentary that Cho Seokbin (ex-insei in Korea, now living in Germany; he is currently on a Go tour in the US) made for the decisive game in the Cherry Blossom Seattle Go Tournament

The title – “Do you think this exchange is good for you?” – seems to be one of Seokbin’s favorite questions during game commentaries.

This is a great question to ask before every move we want to play: just consider what is the opponent’s most logical response to our intended move, and ask ourselves: “Is this exchange good for me?”. This may bring a new perspective on the way we play.

Cherry Blossom Tournament – and Cho Seokbin

Monday, April 23rd, 2007
I played yesterday in the Seattle Cherry Blossom Tournament – which was held at the Seattle Center, together with the Cherry Blossom Festival,the annual Japanese event here in Seattle. I managed to win the tournament with 3-0 (normally there are 4 rounds, but the 3rd one ran late and it wasn’t time for the 4th one for some players) after a lucky win against Steve Stringfellow (6 dan AGA). The highlight of the day though was the visit by Cho Seokbin (also spelled Cho Seok Bin in some other sources) – the famous ex-insei from Korea (just to avoid confusion: many insei from Korea are as strong as professional players) who is now living in Europe (Germany) and winning a lot of tournaments there. Seokbin is on a Go tour in the US – he is in Seattle for the next week or so, and will visit Tacoma and Portland next. He is not only a very strong player, but also a great Go teacher: he commented my final game with Steve, and today he gave a very nice lecture on joseki – I’ll post both the game commentary and some highlights form the lecture on my website in the next few days. Just in case you are in the Seattle area (or nearby): Cho Seokbin will present another lecture on Tuesday, April 24th at the Seattle Go Center (from 7 pm), and will play simultaneous games on Wednesday, April 25th, also at the Seattle Go Center, from 6 pm to 9 pm. Also, if you are interested in one-on-one lessons with Cho Seokbin while he is in the US, please send an email to Jon Boley (”jon at”).

Beyond joseki – and Go World

Friday, April 20th, 2007
I wrote a new lesson: “Beyond joseki”. The reason was that I already found enough (as in 3) English Go literature references to professionals playing tenuki in the famous close-combat taisha joseki (which is famous for getting one into trouble even without playing tenuki…). The most recent source I found a taisha tenuki example in was Go World 43, which was published way back in 1986. I bought one copy of each older issue that Kiseido still had in stock about 1-2 years ago, but only very recently (couple of weeks ago) started to read them. What I do is read on the bus the articles and problems, and study the game commentaries at home, on a real goban. This is how I found the wonderful “Commentary on a Commentary” article with 3 young professionals that comment in 1985 on that year’s Meijin title game 2; then Takemiya sensei comes and comments on their comments. One of the 3 young professionals was Tei Meiko sensei, who was insei instructor when I was insei in Japan. And back to Go World: even with getting all available printed archive issues, I only used to have the issues from 40 to 108. I’ll soon have the whole collection, though, in PDF format, since I just ordered it online from

The art of sacrifice

Tuesday, March 27th, 2007
I wrote a new lesson titled “The art of sacrifice” – inspired by a game I watched on IGS today. It is about the following position (White to play):

Dia. 1

Kosumi-Tsuke: Use and Abuse

Wednesday, March 14th, 2007
I just finished a new article/lesson, titled “Kosumi-Tsuke: Use and Abuse”.

It is about when to use and when to avoid kosumi-tsuke, and it is based on an article I wrote for a (now defunct) online Romanian Go journal couple of years ago. I think the motivation for the original article was the fact that I’m myself a kosumi-tsuke abuser – I tend to overplay it a lot. I’m recovering now :-) It is longer than the normal lessons on and it is more targeted towards fundamentals, I hope – both of which are requests made by users via the feedback system on the website. I hope you’ll find it useful!
