NOW Karjakin missed his great chance 19...Qg5! (game 8)

[zenpawn]

Anand never did that, Kramnik never did that, and, most probably, Karyakin will never do that.

Nevertheless, I have little doubt Kasparov considers both to be quite worthy Champions!

not at all, he says both did not fulfill the requirements for the job. (and he is rigth of course)

Hence the "nevertheless."

[Lyudmil Tsvetkov]

Champion charisma is not completely related to his tournament performance... That performance has to be constant for a while and needs to have some personal aura that fascinates people.

it would be good for chess to have a champion who reigns supreme for a prolonged period of time.

chess is not like other physical sports, where tropheys could change hands every year or so.

becoming first at chess requires much bigger effort than being first at any physical sport. sporting tricks are learned much faster than all the knowledge chess includes.
