Life In 19x19

I wouldn't go crazy over whether to teach new AI joseki or old-time joseki. It depends on what is most used within a group of players. Some like AI style, while others like the 20th Century stuff. Not everyone will understand enough technique to be able to play AI-style (the last frontier). I would sooner have a group of players replay Honinbo Dosaku's games and play freely in their own games, applying what they learned from Dosaku's games. AI style is a very deep rabbit hole, so I wouldn't touch it until I'm 2D or stronger, at least without professional commentary to explain it.

Understanding joseki requires two things. One, a solid understanding of life & death and tesuji to know how the sequences arise in the first place and, two, a working understanding of opening theory to know how the choice of joseki impacts the strategic outlook of a game. Last Saturday I attended a micro-gathering with Christopher Sagner 6D on opening theory and direction of play. He told us that there are situations in which playing out a joseki to completion is actually counterproductive.

I've recently tried to claw my way out of my dusty old cave so I can help new go players. Those who are coming into the game with only the AI openings to observe know (nor care) little about the previous three thousand years of joseki research. To that end, I have acquired K89 and K90 from Kiseido. https://www.kiseidopublishing.com/Other.htm

The two main novelties by AI which players of all strength are adopting these days are the immediate 3-3 and the attachment after approaching. None of these are a deeper rabbit hole than the classic joseki. The ramifications of 3-3 are no more than those of taisha or avalanche.

The complexity an ai follower calls upon himself is the opponent Moyo which arises from consecutive 3-3 invasions. AI is more comfortable dealing with that than the common man. Which is why it might be wise to keep a balance between territory and influence.

Just like in the old days
