Thanks for your comment.
In the real chess world there always has been a bit of a lonely life for the players. Chess players travel all around the place all the time, need to study many hours daily to keep at the top, and their trade is almost unknown to the public. They can't just go and share all their creative ideas with anyone, as a guitarist may share his music. It is also hard to make enough money to support a family, so in that sense they usually fall on the single side of life. The image of a chess player and loneliness is not farfetched.
