Kim Chaeyeong
Kim Chaeyeong (or Chaeyoung, which is not Revised Romanization but more intuitive for English speakers to pronounce reasonably accurately; Hangul: 김채영, Hanja: 金彩瑛) is a female Korean 9-dan professional player, born 15 Jan 1996.
She is the eldest daughter of Kim Sung-Rae and his wife Lee So-yoon who also taught baduk for many years, and elder sister of Kim Dayoung. They are the first Korean family with three professionals.
Chaeyeong’s other teachers were Yang Jae-ho, Choi Gyu-byeong, and Lee Jeong-woo. She qualified as a professional on 28 Apr 2011, aged 15. In September of the same year, she entered the 7th Siptan.

Name
Her given name is also written Chaeyoung, e.g. on Go Ratings and Go4Go. Go To Everyone confusingly calls her Kim Jaeyoung, which is often a male given name e.g., Choi Jaeyoung 8p. The first syllables have different Hangul, Hanja, pronunciations, and meanings; the last syllable has the same pronunciation and same Hangul, but different Hanja so different meaning:
- Chaeyeong: Hangul: 채영; Hanja: 彩瑛; IPA: /t͡ɕʰɛ.jʌŋ/ (aspirated). The 채/彩/Chae character means: “colour” or “to pick/gather”. The 영/瑛/yeong character, common to both names in Hangul but not in Hanja, means “crystal”, “shining gemstone”, or “lustrous jade”. Thus the name means “Radiant crystal” or "Colourful gem”, and is mainly given to females. Chaeyoung’s younger sister Kim Dayoung has the same last character in her name, 다영 (多瑛), plus Da = “many”, “abundant”, hence her name means “abundant brilliance”, “plentiful shining gems”, or “great radiance”. Sharing a character is common in Korean and Chinese families, often a generational name, albeit usually the first character.
- Jaeyeong: Hangul: 재영 Hanja: 宰榮; IPA: /t͡ɕɛ.jʌŋ/ (non-aspirated). The 재/宰/Jae character means “talent” or “wealth”, and the 영/榮/yeong character in this case means “glory”, “prosperity”, or “honor”. So the name means “Glorious ruler” or “Prosperous leader”, and is mainly given to males.

On the 2025-01-01 rating list, Kim Chaeyeong is the

On the Korean ranking list of 6 Jan 2025, she overtook O Yujin to become #3 female, and moved up 13 places to #83 in the overall rankings, showing the largest increase among players in the top 100.

Winning 29th Women's Kuksu after her other win 10 years previously
Choi Jung 9p had a huge plus score against Kim, and had beaten her in five previous finals, this time Kim beat Choi semifinal on 7 Dec (W+R). Then she faced prodigy “genius girl” Nakamura Sumire 3p, who had a 3–0 score against her in official games. But Kim won the final 2–0. Kim commented after the first game (B+R):
I watched all three games of the Women's Kisung Championship finals with great interest, and I think Sumire must have had a lot of regrets (she lost 1–2 to Choi Jung after winning the first game). However, I think she showed that her skills have risen to the top level. That’s why I was able to prepare without any pressure.
Sumire seems to play very well when she plays according to her style. When I first played against Sumire, I felt pressured because she was so young and she was getting a lot of attention, but now her skills have really improved, and I don’t feel pressured. Just like the first game of the final, I will play the second game without thinking of it as a match that will decide the winner.
After the second game (W+R), Kim said:
Watching all three games of the Women's Kisung Championship, I felt that Sumire liked to make her shape bigger. In both games of the final of this Women’s Go Championship, I prevented Sumire from making her shape bigger. I prevented Sumire from doing what she likes and is good at. I think this was the reason for my victory.
First of all, I’m dazed because it hasn’t been that long since the baduk match ended. I’m really happy, and I’m happy that I’ve done better than I expected this year.
I thought it was a similar flow to yesterday. At first, I thought it was okay, but later, as Sumire said during the review, if she had come to catch it accurately, there would have been no time and it would have been difficult to be sure about surviving. It was dangerous because I couldn’t see the way to survive, but when I made a shape of a hogu (tiger's mouth), I thought I survived.
At the awards ceremony, Kim said:
I first won the Women’s Go Championship in 2014 after I entered the professional ranks, so it feels really strange to win again after 10 years. It was also my first time playing a final against a player who was much younger than me, so I feel grateful that we can continue to compete for such a long time.
She and fellow 28-year-old female 9-dan, Female Kisung Choi Jung, are on the cover of the monthly ''Baduk'' magazine for Jan 2025.

Views on female and male players
In an interview after Kim first became a professional, she was asked:
“They say that the task for female players is to develop the skills to compete on equal terms with men. What do you think?”
Kim responded:
“I also suffered from competition with male opponents. There were often cases where male students who were not as good as me would surpass me within a year. Nevertheless, I believe that there will come a day when female players will not be particularly inferior to male players. If we keep working hard and time passes, it will be possible.”
But in the 2023–2024 KB Kookmin Bank Baduk League, which ended in May 2024, she was the only woman and helped her team, Ulsan Korea Zinc, to victory.
Personal life
On 8 March 2025, Kim Chaeyeong (29) married fellow 9p Park Ha-min (27), after dating for 6 years. They are the 12th Korean all-professional couple, and only the second 18-dan couple in the world (after Jiang Zhujiu and Rui Naiwei who married in 1992).
