Name

Her name is not always transcribed consistently. It is pronounced IPA: /hʌ sʌ hjʌn/, where all vowels are /ʌ/, similar to the vowel in the English word sun. Spellings like Heo Seo-hyeon or Huh Suhhyun are internally consistent, representing the same vowel with the same Latin letters, while “Heo Suhhyun” and “Heo Seohyun” (as spelled on Go Ratings and Go4Go are not.

Her given name Seo-hyeon means a precious or auspicious person, literally “precious jade”.

In the semifinal, she beat prodigy Nakamura Sumire for the first time on 9 Sep, after losing their previous 3 official games.
