What makes the main difference in the careers of Carlsen and Karyakin is sponsorship money and support from Microsoft which Carlsen has.
This has been why the Russians (With State sponsorship) have performed so strongly, compared to the U.S. players with no state sponsorship.
Sergey is a very respectfull (And respectable) young man. (Based on my relationship with him.) I think he is a great example of someone with extraordinary talent who also possesses humility beyond his years.
It is also my opinion that he has not even come close to realizing his full potential.
If anyone out there is interested in career sponsorship of GM Karjakin, (A true role model.) you are welcome to contact me directly.

I am able to also provide sponsorship assistance with GMs Kamsky and Akobian.
