Tenshii - new 9-dan on KGS

Tenshii started to played on KGS on March 21. He won 5 handicap games straight, including 6-stones game against 2-dan.
Here is the first game he lost.

My impressions: 6 stones against strong 3-dan is too much! He cannot give him more than 3-4. I know several Russian 4-5d players, who are only 3-dan on KGS and I cannot imagine how to beat them on 6 handi.

Is "Tenshii" professional? I don't think so, but maybe I am wrong.
