My money is on Wei Yi, 14 yrs old and 2600 rating. But again, many young players showed a lot of promise at a young age, only to fizzle out after hitting their ceiling.
Leko, Karjakin, Bu Xiangzi, Radjabov....etc, come to mind.
There is only Caruana IMO who may have a shot....but he needs to improve greatly by next year and be more consistent.
Wei Yi +1
I think the excuse Anand fans used was that Anand was "hiding preparation" because he valued keeping the world championship title more than winning some silly tournaments. We all saw how that played out
Yeah, that was another of their excuses. "Anand only tries hard in World Championship matches, to save his prep." And whenever I asked them why he had such a hard time in his last match against Gelfand, whom Aronian, Kramnik, or Carlsen would almost certainly have defeated in the regular games, they ignored the question.
Likewise, the Carlsen-haters have cycled through a bunch of excuses over the years, with one perennial being that ratings don't mean very much, and the WC is the true measure of chess skill. I suspect we won't be hearing that one so much anymore either now, but no doubt they'll come up with some new explanations why Carlsen is "overrated", just like a conspiracy-theory nutcase always finds more support for the conspiracy no matter what new evidence comes to light.
