Cho Insun is Korean player, who recently became a pro after defeating a large number of pros in open tournaments (competing as an amateur at that time). He's the first person to do so, since the rules enabling this were only introduced recently.
Younggil's written about Cho Insun and how he qualified on Go Game Guru and trout also gave us a lot of useful info about it here on L19.
Since that original thread's mainly discussing other things now, I thought it might be useful to move the discussion about Cho Insun to here.
Cho's next game in the 39th Myeongin will be against Lee Changho. If he manages to win, there might be even more to discuss then
