"...but when he’s forced to defend he’s hardly stronger than other top players."
The old saying about "The hardest part of chess is winning the won game" has almost been forgotten when it comes to Magnus Carlsen.
Mags is money when it comes to sealing the victory.
Some quotes from a great Caruana interview published at chess24:
On Anand's play: "The problem is that over the whole course of the match he played worse than his opponent and he was unable to get to grips with the complex situation that arose"
"the only time he managed to win in the match it occurred due to Carlsen choosing a terrible variation. In the remaining games he didn’t come close" (apart from in game 6 I guess, see below)
"that situation arose absolutely by chance. What was strange was instead Anand choosing an opening variation that involved a transition to a worse ending for Black. Moreover, it was all well-known. And it was also the type of position in which Magnus is particularly strong. It was simply inexplicable"
On Carlsen: "I consider Carlsen even stronger in rapid time controls"
"He’s considered a great endgame specialist, but when he’s forced to defend he’s hardly stronger than other top players. In the past openings were a weak spot and he had problems with principled players who went for main lines – for example, with Kramnik"
On the WC format: "Of course you could improve the system a lot"
"At the moment the World Champion only needs to win the match for the crown and for the rest of the time he can play how he likes"
"However, to make such changes you need a more effective organisation than FIDE. It’s enough to look at what’s happened to the Grand Prix and the Women’s World Championship. It’s pretty ridiculous"
"of the four planned tournaments one of them was supposed to take place in Tehran, where not all of the players would be able to travel – for instance Gelfand. I had that option, but the tournament was scheduled for the same time as Zurich, in which I’d already agreed to play. Besides, the first two tournaments were organised almost one after the other, although there were plenty of available dates. At about the same time they were holding the Petrosian Memorial, in which I’d have liked to take part but was unable to because three events in a row is too much.Plus over the course of half a year there was no information from them until suddenly we got an e-mail with a demand to take a decision in one week. Two venues for the stages have already been changed: Moscow and Tehran became Khanty-Mansiysk and Tbilisi – no consistency. The prize fund was reduced, so that now if you take a second with you it’s almost impossible to earn anything. That’s unprofessional"
"Do your colleagues share your opinion about the World Championship?
Yes, I’ve talked with them on the topic. The current system has existed for 70 years already and is clearly out of date
And have you talked about it with Carlsen?
No, not with him, but I know he talked about the necessity of getting rid of the Champion’s privileges. However, that was before he won the title. (laughs)"
