I went through the list of LiChess classical top 200 players and collected the FIDE ratings of LiChess classical ratings of anyone who I could verify on FIDE's website as actually having a FIDE rating: LiChess FIDE LiChess username Name 2585 2265 ClassyPlays Thibault Dudognon [FM] 2389 1869 nikkon2006 Nikita Konstantinov ...

It is not proven that Glicko is more accurate. Glicko just solves the problem a different way, with a different emphasis. Consider that all these systems abstract a human mind to a 4 digit number. There's a lot of politics in ratings; it's a touchy subject. If FIDE were to adopt it, they'd produce a new top-100 list, and a lot of GMs would likely be ...

I worked on a Scala implementation a few months ago, although it was a bit unpolished--I should go back to finish it. I at least got some reasonable results from it. If you win every game you play, yes, your rating will grow to be quite high even if you play against only low rated players. The probability that you will win every game against such an ...

As far as I understand the Glicko rating system adds a reliability score to the rating number, which may provide a higher fairness regarding the rating score adjustment calculations. Obviously this might lead to the wrong assumption that there is a correlation between playing rated games and resulting playing strength (since not playing decreases the ...

I am 2300-2450 on lichess blitz, while my FIDE rating is 2300-2350. There is a correlation but there is a large body of players on lichess that are not FIDE rated.

Of course it is possible! All the functions needed for the calculations are available on a scientific calculator, e.g. square root, log, value for pi, etc. The Wikipedia page should get you started. Mark Glickman's page on the system should take you further. This pdf has detailed descriptions and equations for Glicko-2 - http://www.glicko.net/glicko/...

I do agree that ratings seem a bit lower on lichess than on other websites, and actually I find this system much more stable. I am just over 2000 on FIDE elo and about the same on lichess (~2100 classical, ~2000 bullet). I have to say that it is the only place where I got a ranking reasonably near to my real ranking.

The rating system used by Lichess is called Glicko and is different from the FIDE one, called Elo system. This post on Lichess forum gives some insights about the topic: https://lichess.org/qa/6/how-does-the-rating-system-work-on-here The most important thing in the answer, in my point of view is this last paragraph: It's best to think of ratings as "...

IMO, Lichess ratings are a little bit inflated. My rating at lichess topped at ~1750 while my FIDE rating is ~1500. In comparison , chess.com is a little bit less inflated. My Standard (30 min) there is ~1600 which is about the same for the top player I could beat at my level.

Of course, lichess is extremely inflated. Just look at Penguingim1's bullet rating; it is like 3100. In fact, it was almost 3200 at one point. Yet, in real life, Penguingim1 is only rated 2450 or so USCF (which is higher than FIDE). There isn't really a good or direct translation, but perhaps you can estimate. I would say a rough conversion factor between ...

They are roughly the same, but different per type (speed v correspondence). This article from chess.com was really informative. I'm guessing the two sites are relatively comparable: https://www.chess.com/forum/view/general/fide-ratings-vs-chesscom-ratings-explored

There is unfortunately no 'good' way to convert from Glicko-2 to ELO. While a lot of people claim they have a formula, there really isn't any system that maintains the same invariants and distribution curve when converting. That being said, there are some ways you could try and 'convert' your score. For example, you could find people on lichess who have ...

What I wanted to know was does it make a difference if you calculate the results one by one or as one batch? According to Professor Mark E. Glickman - The Glicko-2 system works best when the number of games in a rating period is moderate to large, say an average of at least 10-15 games per player in a rating period. Note the above link also gives ...

From my personal experience, the ratings at lichess and most other online chess websites are drastically overrated in score. I know someone who uses lichess regularly. Although I don't know his USCF rating, he has a score of about 1600 on lichess. Having played him in real life, he seems to be more around 1000-1200 player. Also, my rating on chess.com is ...

If you're interested in use (more than in development), you should give a try to rankade, our ranking system that features rankings, stats, and more. Rankade doesn't use Elo, but its algorithm (called ree algorithm), although more complex, is similar to Elo if you play 1-on-1 matches only. Opposite to Elo and Glicko (here's a comparison), rankade can ...
