Yu Ch'ang-hyeok

Yu Ch'ang-hyeok (유창혁, 劉昌赫, Yoo Changhyuk, b. 25 April 1966 in Seoul, South Korea) is a Korean, professional 9-dan. He was one of Korea's top players from the 1990s to early 2000s; won numerous international titles; and held a short rivalry with Yi Ch'ang-ho in the mid 90s. He is said to have been primarily self-taught, having never been the former pupil of a professional (unlike fellow top compatriots, such as Cho Hun-hyeon & Yi Ch'ang-ho). He was married to MBC TV anchorwoman Kim T'ae-heui (金兌姫), who passed away in 2004 leaving Yu with his two children. Yu has become a well respected TV personality and Korean figure.
