bugcat: There are conflicting statements on this page.
1. reached 8 dan in 2002 (in the same year he reached 300 wins in his career)
2. 9 dan on 28 May 2021 with 200 wins.
The first statement was made by a bare IP on the article's creation in 2009. The second was made by me in July (2021).
My source is the John Power Report, June 4, 2021 edition, which says:
