Comments about our Teacher

  • stibbons: In-Seong's go skills are already legendary, and I bet his pedagogical skills will be soon. The Yunguseng Dojan offers an efficient way to improve your go level very fast.
  • Fabbo: Want somebody who can explain as good as he can play? Then In-seong is the man. He can explain difficult techniques so even a 10k can understand and apply them.
  • cbcvcvcv: So friendly and understanding. He prepares the lectures with subjects taken from Yunguseng games and recent tournament games. He is teaching from his experience and that makes it much more...
  • GoRoGoRo: Congratulations to Master Inseong for his newest victory in Berlin at the "Go to Innovation" tournament!
