:: Igo Hatsuyôron 120 (2022)

Motivation

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.
