The stars really aligned for Gukesh in countless ways, his form and openings hit when and where they needed to, and he was left playing a very out-of-form world champ who wasn't even in the top 20 in the world.
I suspect his record (world champ at 18) will remain intact for many decades yet to come. He attributed much of his success to God, and even as an agnostic - I'm inclined to agree!
Notably he's still nowhere near the strongest player in the world - he's not even the strongest Indian! The world championship in chess can be an odd beast at times.
As to Gukesh's faith, it brings inner peace and happiness, and if you observe the contestants' faces, the difference was evident. Gukesh isn't making a show of being prayerful, he's really doing it. It means he is doing what he is doing for a greater goal, which is always for a worldwide peace and happiness for all human beings, when really performed in harmony with our Creator. If one's religion's purpose is for dominance over others one can never gain inner peace and happiness from it. It must be for personal harmonization with peace and happiness for all human beings, or it is just more mammalian self-righteous warfare.
That's why Rumi says, "You have no idea how little we care for what people say." What he means by this is that a lot of people talk about religion, but what we do and how we feel as a result of our religiosity is the only proof that is accepted by God. Most people do not understand that such proof is evident on people's faces and in the tone of their voice, but you seem to have noticed the reality that Gukesh has it and, sadly, Ding does not.
Gukesh's victory is a way of demonstrating to folks that there are real gains to be had from seeking the peace and happiness of religion for peace and happiness's sake. No religion is superior to others in this respect. No. There are only true seekers and those who merely seek to justify their oppression of others by their religious affiliation.
I extensively explain how this works in my comments over the past week or two.
"The Way goes in." --Rumi
A completely unprepared Magnus vs a 100% prepared opponent will go to a better prepared opponent (See Magnus interviews if you don't believe this). 4-6 months spending memorizing lines is not easy. It is too much work. Magnus has already proven he is GOAT, he doesn't have to prove anything.
But - this doesn't take away achievement from other players, if Magnus doesn't want to be bothered doing all the prep.I wonder if we will say the same thing in any other sport.
Ma Long for example - did not participated in Paris Olympic singles, does that mean Fan Zedong or Truls moregard achievement was any less? Nobody would say that.
It's also worth noting that is he is the reigning Rapid World Champion, the reigning Blitz World Champion, and the reigning Chess World Cup Champion.
He chose not to defend his Classical world title, and has been quite clear about the reasons.
Magnus is, by a landslide, the best tournament player (probably ever) but the world championship for classical is very different than a tournament, and his results there have not been anywhere near the level of his tournament performances.
And Magnus has also stated that he believes he has peaked. Basically - he was going to imminently lose, and I think he wanted to go out undefeated. Notably the one player he was willing to play, Alireza, was the only viable contender who he would expect to have been an overwhelming favourite against.
Also in terms of legacy, the max number of world championship victories is 6. He stopped at 5.
