Apparently, is a fairly recent Korean development from a dozen years ago.[1] It aims to develop a group on either side of the white kakari (develop on both sides).
Cho U played this way against Lee ChangHo on 2005-02-23 during Nongshim Cup,6,Korea,Nongshim -Jared
Bob McGuigan: There was an extensive analysis of this attachment in Go World issue number 87 as part of a series of articles on the Korean Style by Oya Koichi 8p.

Bill: Actually, it has been around for a while. It appears, with variations, in Suzuki and Kitani's Small Joseki Dictionary, published in 1965.
John F. It goes back to 1934 in Japan in the GoGoD database. But then it did not reappear in games we have, except in some instances with more stones round about, until 1991 when it re-emerged in Korea. Mark Hall collected a lot of these games and dubbed the opening the Korean Joseki. We have over 200 examples, and it's still being played widely.

I think this present page is a more polished and erudite discussion of this joseki and that the other page might mostly be made into a discussion page since it mainly consists of analysis by amateurs and examples from amateur games. I agree -fgb
This is my first time commenting on a page, so excuse me if I'm unawares to the proper SL etiquette. In the second diagram, are there any good alternatives to the hane? If not how would one best punish this kind of deviance from the joseki; for example extending towards the center.
emeraldemon: I'm not so good at joseki, but maybe you mean a sequence like this?
I don't think can be at
, because black will crosscut at
and the fight will (probably) be better for black. In this fight black may be slightly better off (and has certainly developed on both sides) but it seems playable.
fractic: Black can play a hane at , after
white will need to make an empty triangle to connect.
miharbio: Yes, this is similar to how it played out in game; white responded at a to connect. Interestingly though, a dan player commented after the game that b would work "more actively" in defending the cut than a.
miharbio: But I was wondering what would happen if was at a..., is the cut at b the best way for black to take advantage?
