Both ratings are absolutely not comparable
Kasim is a professional player, I am not.
I play 10 games/year, he plays maybe 100/year.
Such a player has certainly a much superior opening preparation.
I can´t play promising opening systems like the Najdorf since they require a lot
of homework.

Certainly Kasim is clearly stronger OTB, but that doesn´t mean he understands
every position better than I do.
Also human ratings say nothing about the playing strength against Computer
programs. A 2300 player can easily be better than a 2700 player there.

Any Anti-Computer expert will tell you: This was the ideal position against
programs. Pablo easily would have drawn this position against Hydra.
