The Art of 9x9 Go
I think the Art of 9x9 Go should be given in full. There are few 9x9 games analysed on this site and there should be many more. The small number of 9x9 games analysed here are all interesting, for example https://senseis.xmp.net/?TheArtOf9x9Go%2FR2D04, and I would like to see many more.
More games are to be given at 9 x 9 Go Review repository and The Art of 9 x 9 Go, Superhuman Edition (in coding) at https://9x9go.github.io/superhuman/preface. More at https://github.com/9x9go/superhuman
