Simen Agdestein
Simen was ranked highest at number 16 in the world as a chess player, but it was not easy to combine with an active career as a football player. The football, however, ended soon due to a knee injury, but at least he played eight International games for Norway. He scored his one national team goal during that time.
Simen graduated from the University of Oslo, but has spent almost all of his career on the chess line at NTG. It started in 1998, and his work is still continuing today. Magnus Carlsen is of course the most discussed of his students.
