GMs Wang Yue, Wang Hao, and Hou Yifan of China.
I also had 10 year old Javanna Smith who is playing her first Olympiad for Trinidad & Tobago. She won her first ever Olympiad game today.
In addition, the Olympiad IT Chief Dr. Michael Breidung was kind enough to explain what it takes to have all the games broadcast LIVE during the Olympiad. He is in charge of making sure the the entire procedure is running smooth.
