Yun Hyuk

Korean 8-dan professional.

2p by 2000, 3p in 2001, 4p in 2004, 5p in 2006, 8p in 2019.

(Note: Go4Go has a strange gap in his games between 2011 and 2019, which could mean they're filed under a different romanisation. I'm also surprised he doesn't have an SL article having been a pro for so long, and that "lack" may again be due to a romanisation discrepancy. -- bugcat)
