cool thread
well i watched all his fights some year ago,so i think i know his career well to say answer it
in the first ever edition of K-1 World max(2002),where he was the champ,he defeated 2 big names on that time
Masato who need no introduction and Kaolan Kaovichit Lumpinee champ who used to fight in japan
at 2003 he had some big victories as TKO victory over rising Shootboxing star Andy Souwer and KO victory against the established MMA fighter Duane Ludwig
at 2005 it was a big year of victories for him as well,Defeating the previous year K-1 Max champ Buakaw(BS desicion for sure but..)and a victory over the famous John Wayne parr
at 2006 he had defeated Sato,but i wouldnt consider one of the best of his victories,because sato was too newbie and developing at this year
at 2007 he had a big beatdown victory over Sato,who was growing up a lot as a fighter and was considered as elite at the time,a year later Sato Knocked buakaw out,so...
at 2008 he also had a good year with a doc stop victory over legendary Zambidis due a high knee, a victory over the strong Newcomer Yasuhiro Kido and another Bullshit victory over buakaw(he lost this fight for real,was outclassed,but...)
2010 he had a victory against the Newcomer k-1 max japan Finalist Hiroki Nakajima
since 2010 he had some mid tier victories and crusing lower level chinese opposition,
