Born in Guam, Robson soon after moved with his family to Florida, where his father taught him chess when he was just three years old. From 2004 to 2007, Robson finished in the top 10 at the World Youth Championship and then won SuperNationals in 2005. He defeated his first grandmaster in 2006, the same year he earned the USCF National Master title. Other impressive performances include first place in the 2005 and 2006 Pan-American Youth Championships; the 2009 U.S. Junior Championship; the 2009 World Team Championship; and the 2012 Dallas Invitational.
In 2008, Robson won his first major tournament at the Miami Open, and later that year became the youngest American to win the Grandmaster title, at the age of 14 years, 11 months and 16 days. The mark bested the record held by Hikaru Nakamura and once by the great Bobby Fischer, making Robson one of America’s brightest hopes to another world-elite GM.
Though the University of Texas offered him a chess scholarship, in 2012 Robson decided instead on the SPICE program at Webster University where, just a few months after enrolling, he won the 2012 Webster University SPICE Cup Open and eventually helped the program win three consecutive national titles.
