Below are the pictures and biographies of the professionals scheduled to attend in 2025.


Invitations to professionals are still in progress, this page will be updated as professional attendance is confirmed.



Simul Game Etiquette

  • When the professional player approaches your board for the first move, it is customary to greet them.
  • Do not delay your move. When the pro comes around to your board, make your move.
  • Do not play your move before the pro arrives. It is rude to make the pro find your move.
  • Do show respect for the pro by not discussing your game (or anything else) with bystanders.
  • Do resign when the game is lost. Please resist the temptation to play the game out until the bitter end.
  • Quietly thank the professional, and clear off the board before you leave. In three-game simuls, pros will often do brief analyses after all three games are finished.
  • The event director reserves the right to terminate any games that are clearly lost.



Please do not sign up for more than one simultaneous game until Thursday so that all attendees will have an opportunity to play one. If you have not played a game by Thursday and would like one, please let the staff know and we will give you priority.

Wang9P

Yuan-Jyun Wang, Professional 9 dan - Chinese Taipei Go Association, Taiwan


Yuan-Jyun Wang, born in 1996, became a professional Go player at the age of 11 in 2007 and a 9 dan pro in 2018.  


Yuan-Jyun’s path to professional Go was sparked by the 2007 Ing World Cup for Children in Boston. Initially, he hadn't considered a professional career, but the event revealed the potential for greater access to the international Go community. Inspired, he attempted and succeeded in becoming a pro that same year.


Unwilling to sacrifice his education, he found a way to balance both. With Yuan-Jyun’s persistence and hard work, he rose to become Taiwan's top-ranked player in 2013 during his third year in high school. His Go achievements later secured him the admission to National Tsing Hua University, where he majored in economics and earned his bachelor’s degree within 4 years, all while remaining No.1 Go player in Taiwan. This feat earned him the respect of the university faculty and solidified his reputation as a model of diligence. 


Yuan-Jyun is affectionately called "Lao-Wang" by his online fans. He gained the title 棋王(Go King) at the age of 17 in 2013, which made him the youngest title holder in history of Taiwan. With 23 Taiwanese championships to his name and a runner-up finish at the 2018 JeollaNamdo Kuksu Mountains International Baduk Championship, he remains a leading figure in Taiwanese Go today.  


After graduating from college, Yuan-Jyun started his teaching career, sharing what he has learned with his students, some of whom are now pros. This summer, he is more than ready to participate in and make contributions to the American Go Congress, expecting lots of interactions with all the participants.
