Kim Seungjun
Kim Seungjun (김승준, 金承俊), a.k.a Blackie, is a Korean professional 9 dan player. He is perhaps best known in the West as co-founder with Diana Koszegi (Hungarian 1 dan pro in Korea) of Blackie's International Baduk Academy (BIBA), where many (100+) foreigners have studied. "Blackie" comes from the nickname "black knight" he was called due to his dark complexion.
Uberdude: I studied at BIBA for 2 months in summer 2013, you can get an idea of what life is like there from my journal on L19: http://www.lifein19x19.com/forum/viewtopic.php?t=8451.
