Micro Chinese
Black`s hybrid extension-cum-enclosure at 5 has been appearing quite often in recent pro games, and is associated especially with Kono Rin, although the pattern has been played at least as early as the 1970s (by Ishida Yoshio).
Bob McGuigan: There is a recent NewInGo article on this fuseki.
Tamsin: Hi Bob. I have seen the article you mention. They like the new shape very much ;-) Have you seen Cho Hye Yeon's article on her blog? She explains the ideas behind it nicely.
Cho Hye Yeon refers to this kind of pattern as the "mini-mini-Chinese", but xela has suggested the name "Micro-Chinese", which might be both a little bit easier to say and a good cover-all term for the whole complex. (Cho U has played it with white and there is also the shape shown below.)
