She won her first Championship in 2010 at age 16. I loved being in a room filled with chess enthusiasts, at the oldest running chess club in the United States, to hear her speak for a hour. (I lost my autographed flyer on my way to the station but at least I took a picture of it 😅)”. Photo: renejr11.
