The list of orphans, or "unreachable" pages, keeps growing. If I find the time I'll try to link them from a good spot. The best practice remains to create pages from an existing page, so that they are naturally linked.
Many pages are in the same area of professional Go, so they should naturally find a parent.
yoikopomo was a spam page. I requested deletion of it on the day of its creation two months ago.
China-Korea Super League, Supreme Player, Supreme Female Player and the Teikei Cup can all be linked from the professional tournaments page.
Hino Shota can be linked from the alphabetic professionals list in this section -- Hikosaka 彦, Hisai 久井, Hisajima 久島. He goes after Hikosaka.
Etiquette Title could attach to Big Titles.
As for Westerners Beating 9d Pros, seems like it'd go alright in Go history. So would 2021 in the Big Seven Titles.
I recommend linking Japanese for Interpreting Websites from Japanese era conversion.
The parent page of the Hitachi tsumego is Hitachi Go problems.
Where to Play Go is a tool of BadukClub.
