Wow... No single comment to this entry after one week. I must be 3000+ ELO creating uninteresting subjects! And it just takes a title like: "Would Fischer beat Ding Liren?" to get over 100 replies a day :D The subject remains though original and totally off track from the mantras we are used to read in chess forums. Comes to mind the recent fine article about the five types of forum entries...Wait: is that why??
Ding Liren: a special one?

Wei Yi is not good in blitz too. So we have ample proof that you don't have to be so good in blitz to be good in chess.

Caruana is the same way. His blitz is much worse compared to his peers.
Really? On ICC, Caruana's #1 in blitz, #2 in the 3-minute pool, and #3 in the 5-minute pool.
I don't entirely trust FIDE's blitz ratings. Let's see how he does at the next blitz championships.

This is all relative. Caruana's FIDE blitz rating is 2665, based on five events. Wei Yi's 2606 is also based on five events.

Ding Liren's last FIDE blitz rating was for a single event in 2014. His entire blitz record is comprised of 4 events. He's obviously improved.

Caruana is the same way. His blitz is much worse compared to his peers.

Anybody knows, how come there's such a short record of blitz and rapid games for some top GMs with a respectfully long term experience in classic chess? They must avoid such tournaments, aware of their lower performance, I guess...

No, N_Parma, the reason there are so few rated blitz events is because it's so new to FIDE. There have been blitz events for years, but few of them ever get rated. People rarely travel great distances to play in blitz events.
Usually, blitz events are part of another event, such as an Olympiad or a match against another country. Recently, blitz events have been used at the start of a few major events to set up the seeding for the main event. I hope those become more common. Until they do become more common, online blitz ratings over on ICC will be far more reliable than FIDE's blitz ratings because GMs play far more blitz games there.

Ding Liren is indeed a special one. He is now world number 7 and just reached 2782 in the live ratings. First player from China to do so.
The way he is going and his young age taken into account, could he be the 1st Chinese player to crack 2800?

Thanks for your enlightening answer, SmyslovFan. That must be the reason why FIDE blitz ratings aren't reliable yet. However, I couldn't come across with any good looking ICC ranking, just one at http://staff.cs.utu.fi/~juhkivij/chess/icc_best_en.shtml in which Nakamura seems to be the only known player -well, there are a few others like Grishuk or Vallejo, even Caruana shows up in one list. They all use nicknames and Elo's seem out of control. I guess we'll have to wait some time until we know if being good at chess means being good at blitz as well.

Ding is doing great at the World Cup. He will no doubt come out of it with over 2800, if not straight a candidate to the World Championship. The more I see his games, the more I fall in love with his style.
He really is a special one.
Ding and Wei are both great, but I believe Wei will be a truly special one, like Magnus, except much more aggressive.
Wei could be the first WC from China some day, Ding I believe will be a long time top ten player, but I have doubts he will be WC.
Ding Liren just got into the world top-10 of classic chess. The rest of first line GMs have very high ratings as well in rapid and blitz chess. Enough ELO at least to be on top. Only DIng Liren doesn't.
I read in an interview his explanation: "I just can't keep up with the rivals [when playing rapid or blitz]".
Should that mean Ding solves positions on the go, not by memorizing lines or patterns, just analysing every single position calmly?
I find the subject fascinating -and a beacon of hope- for those who don't like to abuse their memory or living obsessed with chess to the point of playing almost like robots (which basically blitz chess in the end is)
