Chae Yoo Jung (now Chae Yu Jung) is a left-handed mixed doubles specialist (who also plays level doubles). She shot into the limelight when she won the deciding match of the 2017 Sudirman Cup final, but previously had some success playing with Shin Baek Cheol (narrowly missing out on Olympic qualification). After Shin Baek Cheol left, she resumed her youth partnership with Choi Sol Gyu, with whom she achieved Sudirman Cup success. Her playing style is focused on net play and interceptions, which makes her exciting to watch. Recently she's been playing with Seo Sung Jae, but it's not clear how long term the partnership will be; they'll need some results at bigger tournaments before any conclusions can be reached. That said, I feel like her partnership with Seo Sung Jae is more effective (than Choi Sol Gyu) for 2 reasons: - Seo Sung Jae has a more effective attack - They seem to execute more varied styles of play 2 consecutive finals is also a good start to their partnership, even if they're only New Zealand and Australia. That said, an absence of top pairs means they haven't been put through a real test yet.
