The curious thing is that Carlsen’s ELO didnt’t get nibbled even after all theese consequent draws. They’re too close.

That's because ELO only gets updated at the end of a tournament, not every game.

  At https://2700chess.com/ https://2700chess.com/ you can see the live rating with the effect of each game since the last periodic FIDE update. Expanding either Carlsen's or Caruana's rows will show you a list of the seven games since the last update, with a change of 0.0 next to each.

  That's interesting. Do you have a source for that? I always believed it is because either FIDE ratings are only updated once a month (see 7.1[1]) or because their ELO is too close, therefore the prob. of winning is 0.5 for both anyways.

    That's not true about Elo being updated particularly at the end of tournaments - either official/FIDE ratings or live ratings. I heard (possibly from the Chess24 commentators) that if their difference in rating was 4 or more, each draw would bring them closer together in live rating - Magnus would lose rating with each draw; but as it's 3, their ratings don't change. i.e. anacleto was right, thomasahle wrong. Also, Elo isn't an acronym (ELO) as one might think - it's named after its inventor Arpad Elo. https://en.wikipedia.org/wiki/Elo_rating_system https://en.wikipedia.org/wiki/Elo_rating_system Interestingly, when I first looked at this page, most of the good/correct comments were voted down, most of the bad ones not, it was weird. (It made me suspect that other HN pages are like that but I don't know it! - I know chess better than most subjects discussed on here) But that has now almost totally been corrected.

      Could it just be that the most recent comments were listed first? I think HN does that to give them a chance to get read and voted on.

  FIDE also calculates a game-by-game "live" rating. It's not normally published but it is used for some title requirements. For example the requirements for the most common way to earn the GM title include a requirement that your rating has reached 2500. The live rating is used for that.
