I found this fascinating web-site while looking at the recent Honinbo tournament. It contains some 7420 records of Japanese title matches, many with AI graph analysis, for example the 76th Honinbo is at:

https://igo-kifu.com/event/honinbo

The AI graph starts with White at 57% and Black at 42% - does anyone know what AI produces these graphs?

In some of the games the AI shows it's very one-sided quite early on, for example in the final game of the 7th Kisei - when Fujisawa lost his title to Cho:

https://igo-kifu.com/kifu/4430

Cho won by 1.5 points, but the AI shows it is almost all over at move 149 out of 268

Any hints on the starting percentages for AI welcome.

Take Care - John

From White starting ahead on the AI graph with 5.5 komi I assume they have not set up an AI correctly to take into account the actual komi of the game, but stuck on 7.5.
