Today’s game is an illustration of how things were, through the medium of the joseki in the top left corner. When I was recording games from the Korean Yearbooks (and cursing their many printing errors) from 1992 onwards, there were many variations of this joseki being tried out in Korea in 1992 and 1993. I then saw a comment by a Japanese professional sometime around 1994 in Go World that the first time a particular sequence had been played by professionals was X. Of course, it was a variant of this joseki being playerd for the first time in Japan. Nowadays, there is much more knowledge of what is going on in each country and what experiments are being tried.
Best wishes.
