Yesterday they asked the same question on Yoo Changhyuk's official website:
http://www.youchanghyuk.com/news/viewpage.asp?pagec=&seq=10307&gubun=all
Marriag won 20 games straight as 9-dan, so he must be one of the superstars.
He crushed lot of Chinese pros, including 4k_grubby, daxiang, lxlx, hua, heibeil ...
9-dan is highest rank on Tygem, but there is the rule, that if you win 20 games straight, you get 2-grades promotion.
So, 철이(P)/Marriag(P) can be the first 11-dan on the server!

According to that Korean article, there are 3 candidates: Lee Changho, Choi Chelhan and Park Yeunhun.
