Bill has mentioned a couple of times recently that the short keima, as opposed to the long ogeima, is a relatively recent response to an approach against a star stone.

Indeed, GoGoD's first example is from 1934. Since it was a serious game - the Oteai - I thought I would look up the commentary.

As was the practice then, both players provided post-mortem thoughts. Black was Fukuda Masayoshi. The relevant move was 9, and I've inserted his comment in the sgf file. Nothing earth-shattering. Not even any sense of trying something new. On the other hand, it was clear a fuseki-inspired response and not a joseki-inspired response - a pro's a pro!

The continuation was unusual - again nothing joseki-like. This keima wasn't tried again for a couple of years, Perhaps strangely, it wasn't discussed in Shin Fuseki-ho. But the first example of the now famous joseki where A answers B' keima with a keima slide into the corner, B defends at the 3-3 point and A extends two spaces along the side was due to Kitani in a game against Go Seigen, in 1942, but it wasn't really taken up until the 1950s, and even then only patchily.

Thanks, John.

Interesting play in the bottom left corner. Especially to those who think that is a new idea.
