Semeai 101

Recently on the ngd Discord server there has been some discussion about how to precisely read out capturing races, so I thought to write a post on them. As the topic is broad, it is of course impossible for a single post to cover even nearly all of it, but hopefully this will at least get the reader started.

Contemporary Go Terms: Airport and Toothpaste

Learning new go terms has a bigger impact on one’s improvement than many players give credit for. While the terms themselves are mere placeholders, they refer to shapes and strategical concepts in the game that are usually worth learning. For instance, imagine not having a term for ‘hane’ or ‘one-space jump’; besides the terms allowing for smooth communication between players, …

How should we learn from the AI?

My recent work got me again thinking about the nature of learning and understanding. More precisely, I got interested in thinking about the best way to use the ai in go studies.

Recent research (for example, Thinking, Fast and Slow by Daniel Kahneman) suggests that expertise in a domain is not a single skill but rather a large collection of …

Impact of Go AI on the Professional Go World – Response

Lee Hajin recently published an interesting article on the ‘Impact of Go ai on the Professional Go World’ on I found myself disagreeing with many of her points, and so decided to write my own remarks on the topic. Note that my intention is not to attack or ‘bash’ Lee’s opinions, but rather to bring forth another point of …

Go Variant Server

As we know, recently the prevalence of go ai software has made it hard to organise tournaments online. If you organise a tournament with no surveillance, ai-users will inevitably pop up; and if you want to organise a prestigious and serious tournament, you have to do something like the 2020 Korea Prime Minister’s Cup, where all participants are required …

Area or territory – The future of go rules

(The historical information in this article is based on The History of Go Rules by Chen Zuyuan.)

As we saw in the first half of this post, go was first played with stone scoring, then with territory scoring, and then also with area scoring. Although territory scoring is nowadays attributed to the Japanese rules, they, similarly to the two …

Area or territory – A brief history of go rules

Tagua go stone

High-quality go stones are traditionally made of slate and shell. The cheapest, relatively thin stones cost around €150–200 for a set, and the highest-quality, thick stones can easily cost €10,000 or more.

Recently, in Japan it has become a problem that big enough hamaguri clams, which are used for white go stones, are getting increasingly rare due to overfishing. Because …

Is ‘fair’ komi necessarily an integer?

One popular topic among go players is: what is the ‘correct’ value of the komi?

There are many ways to approach this question. For example in tournaments, it is useful to have the 0.5 in 6.5 (or 7.5) to prevent draws; after all, tournaments need a winner, and a game that ends in a tie often has to be replayed. …
