ChenWon Cup is not easy even for Lee SeDol and Lee ChangHo 9Dan.

From 6^th ChenWon Cup, Lee ChangHo 9Dan has refused to attend this ChenWon Cup for 10 years and re-attend from 2012. But he has not put his name on the final of ChenWon Cup since then.

Lee Sedol 9Dan has won 5^th ChenWon Cup when he was a hot rookie but we can't see his name anymore in ChenWon Cup this year.

Byun Sangil won against Lee SeDol by resign with black in the round 16 of 19^th ChenWon Cup on 7^th.

There were several exchanges on the lower sides but Lee SeDol 9Dan was ahead by little as the game went to the end. But Lee Sedol 9Dan lost points in the end game and Byun Sangil turned it up in the end game. As Lee SeDol 9Dan knew it was just half point, he just resigned.
