Post subject:  Igo Hatsuyōron #120 :: 2022 Update of our website

The participation in Karl Desfontaines' European Go Journal article (March issue) on implementing KataGo to try and solve Igo Hatsuyōron 120 made me realise that some initial inconsistencies could be attributed to the fact that the "significant" contents of our website were extremely difficult to access due to its very confusing structure, even for professional players.
So I set about a rewrite in a kind of "open countryside".

This   New Story Line 2022   (comprehensive, but nevertheless extensive) will explain all the elements of Inoue Dōsetsu Inseki's masterpiece in a coherent, rewritten, form – based on our current state of knowledge.
It aims at providing a simpler approach to the problem, allowing interested Go players to explore all the beauties of the problem (in the desired level of detail) without having to trudge through the very confusing maze of the historical sequence of our analyses (what this website was never originally intended for).
Different colours of the board surface not only indicate the different phases of problem solving, but also mark the authorship of the respective moves – starting with Fujisawa Hideyuki 9p and ending with KataGo.

For easy reminder, its start page is mirrored at https://igohatsuyoron120.de/2022.htm.

Apart from that, the 2022 update also contains KataGo's analysis results on issues that had caused us massive headaches in the early days of our engagement with the problem (what the original planning was):

It was not possible for me to check everything and anything several times. So if you stumble across any bugs, please let me know.

Not a bug as such, but you refer to playing white on first move as maybe a homage to go's Chinese origins.

However, game records with White playing first in Japan exist around this time, and one of them is Inoue Dosetsu Inseki (GoGoD 16687-03-07a). This was against Lord Makino and may have some sort of deferential or ceremonial significance, but there are other examples where neither of the two players is an aristocrat. These may still have an element of deference, in that they were played in the presence of someone august, but it may also have been the case that playing with White first was then either normal or common, or players just didn't care. At any rate, there seem to be reason to assume a Chinese connection.

There is also the possibility that colours were swapped in the printing process, which we know has happened with other old books.
