It looked overplay at first sight but Yun Chanhee's nexth moves made it possible. Shin Jinseo couldn't control his mind and played with best moves from Yun Chanhee's great moves and it was end.

Yun Chanhee 5P won against Shin Jinseo 5P by resign with black in the round 8 of 21th GS Caltex Cup on 24th March. 

Lee Heesung 9P commented that Yun 5P's current games are very good and his mind control is also great. I think we should watch him later as well. 

Yun Chanhee 5P is 10 years older than Shin Jinseo 5P. He has been members of Baduk league for several years, and showed good games in the many tournaments.
