From the recent LeeKibong's interview in Goama magazine
Q: What
do you think about 9-dan level players on KGS? Can we say that all of them have professional strength?
A: They
are almost professional level. Once you are at that level it is very
difficult to see the gap between player's strength.
Q: On KGS
you played lot of games with Ilya Shikshin (roln111) and Artem Kachanovsky (artem92). What can you
tell about their levels? Which class of inseis (youngusen) can they currently be in Korea?
A:
Artem tried out for the Yonguseng once, but was not able to. The
difference between 1st group, and 10th group is very small. 10th level
insei are still very strong players.
