Where does the chinese 6 dan information come from? Chinese 6d is hard to get and she plays weaker than many chinese 5d I know. It is not mentioned on her website or KGS info and I expect if she really was chinese 6d she would want to advertise that fact. A 3/4d BGA friend played her and had a good chance of winning, despite losing. He also played Matthew Macfadyen 6d BGA and said Matthew was much stronger and he never really stood a chance. Matthew is weaker than Chinese 6d.
I deleted the KGS 9d as from my inspection of the KGS archives she has not been KGS 9d since the ranking system changed with KGS 3 back in September 2006. She was recently 9d? not 9d which is very different. Kyu players can get 9d? with quirks in the KGS rank system.
Teachers on KGS have a habit of using accounts with inflated ranks to attract students. I don't think Sensei's library should participate in this flattery and deception.
