Hekomi

Hekomi is a Japanese go term that is fairly often used in Japanese go jargon, but is virtually nonexistent in its English counterpart. ‘Hekomi’ is usually translated ‘dent’ or ‘depression’; but in go terms, I find the former translation not very descriptive while the latter will get confused with the mental state. ‘Hollow’ would make for a more fitting noun …

Sunday Problem #5

Black to play.

Solution
Black’s sacrifice technique with 3 and 5 is the key. This provides the two other black stones an extra liberty that allows Black to win a local capturing race with 7–11.

NGD online league review thread

This post is intended for gathering reviews of our online league service from our students.

As a teacher and webmaster of Nordic Go Dojo, I’m not qualified to comment on our service myself, but I can certainly praise our go community! There are often lively go discussions going on on our Discord server and in our game review comment threads, and I’m grateful for how willing our stronger students are to help less experienced players. Several of our participants have even gone so far as to help improve our website by reporting bugs and writing code for the KataGo score graph tool.

Student reviews are added to this post as they are written.

What is a professional go player?

Sunday Problem #4

This problem was created by Lee Eodeokdung 1p. He showed to me at the European Go Congress 2017, and it quickly became one of my favourite tsumego.

Black to play.

Solution
White 2 is the strongest resistance to Black’s attachment of 1. Following...
...after black 7, White dies in a double ko. This is still better for White than dying unconditionally, as the group will supply infinite ko threats.

Winrate graphs in AI-analysed games; and sample NGD game review

Courtesy of Mikho, posts on this website now show rudimentary winrate graphs for ai-analysed games. This feature is still work in progress; there is a plan to also include KataGo scoreMeans in the graphs, as well as interaction between the graph and the sgf reader. Still, even now in this intermediate form, the graph should be a welcome …
