The website 2700chess.com has a database with the FIDE ratings (from May 1st, 2019). Their search form only offers the option to show the top 50 or 100 players satisfying the search results, but it's possible to modify the submit request and ask for the top 5000 instead. When I do that, I get 808 results: So the other 700 must have ratings lower than 2500 ...

Most chess sites use some variant of the Elo rating system If you have a much higher rating than your opponent, the expectation is that you will win. So if you do win, then we haven't gained that much information, so the change in rating for both you and your opponent will be small. If your opponent wins, there will be a much larger change in rating as ...

Using the official FIDE rating lists, there are 954 players with above 2500 ELO. Currently, FIDE has awarded 1668 players the title of "Grandmaster". Filtering out inactive players, there are 1334 GMs and 729 players with "grandmaster strength". There are GMs with a current ELO as low as 2138. Keep in mind that titles can be awarded for achieving certain ...

I looked at the data briefly and got some interesting conclusions. I used data from FIDE webpage for january in years 2006-2019. I calculated each player's rating change in consecutive years and used player's age in the first of the two as the age when this rating change occurred. Then I simply calculated the average. The result is this: As you can see, ...

Rating is a lagging indicator. That is, it gives an estimate of playing strength in the past. Therefore by definition players who are improving are underrated and players who are declining in strength are overrated. Therefore as a first step if you can enter late you should look at the age profile of the entries and avoid entering tournaments with lots of ...

OK, so the tournament was the Rattenberger Schnellschach-Open 2019 Tiroler Einzelmeisterschaft im Schnellschach It was a Swiss tournament. Here are your results from the tournament. One of your opponents, Karl-Heinz Staudacher, has no rating. You should exclude your result against him altogether. One of your opponents, Manuel Keßler, has a standard rating ...

What you have to understand is, first, that any rating is just a comparison of players within that pool. So a 2200 on chess.com is not the same as 2200 on lichess.com, or on ICC. They are probably close, but it is not the same. Second, you need to realize that your three game sample is just not enough to draw any valid conclusions. You are human, so even if ...

This trick is prevalent in all levels. Of course, depending on the position, your ability to muddy the waters varies. Against much higher rated opponents, it is typical that they will gain an advantage without giving you much counterplay. Nevertheless, in all levels of the game, the losing side will try to muster some counterplay to get back into the game. ...

Why didn't I get a FIDE rating? Probably because you didn't meet the requirements to get a rating. According to FIDE Rating Regulations effective from 1 July 2017 (sorry no link currently because FIDE have munged their site and you have to search withing the site): Official FIDE Rating List 7.1 On the first day of each month, the QC shall ...

Based on the screenshot, I believe this was a Swiss tournament. In that case, you ignore the unrated opponents. Do not average in a rating of 0, and do not count the results against those players. The Ra is the average rating of your rated opponents, not the average rating of the entire tournament, based on this line: In a Swiss or Team tournament: this is ...

In general, countries with many tournaments but not a super strong "chess culture". I think China and Iran tend to not have so many tournaments (if I recall correctly), which explains why their players tend to be more underrated. Meanwhile, European countries have lots of FIDE rated events (some clubs have such events every weekend!). Since they have more ...

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 "...

Given Carlsen's 2882 current rating and the fact that he also reached this rating in 2014, it seems likely that at some point he had a year with a performance rating higher than your 2892 figure. (I calculated Carlsen's 2013 performance rating as 2890 [47 points in 69 games against an average opponent of 2757] but it's tedious enough to calculate that I don'...

It is better to look at every game. Only looking at tournament performances causes you to lose some important information. Should a 4 round tournament count the same as a 9 round tournament? Under your system, they count the same. That doesn't seem right. I had a tournament recently where I won against 3 low-rated players and drew against a player rated ...

As suggested in the question I have taken FIDE rating data from 1992 (when active/inactive flags were first introduced) through to September 2019 taken from Olimpbase and FIDE and loaded it into a database which has allowed me to run SQL queries against the data to get some answers for this question. I looked at average decline in playing strength for ...

No. A good arbiter needs to know the Laws of Chess, but that's about it. There's no need to refer to tactics or openings or strategy when you're arbitering. After all, the days of adjudication are over. I've heard that there are a lot of arbiters with titles that aren't good arbiters, but that wouldn't be solved with imposing a minimum rating. In fact, such ...

If you're losing, then attempting to complicate matters is a good idea. It gives your opponent a chance to go wrong and you a chance to recover. I've saved many games by aggressive moves that upon scrutiny could be found wanting. If your opponent stays calm and analyzes them thoroughly, then chances are they probably won't work. But nothing has been lost by ...

Handicapping I've played in blitz tournaments where the higher rated player was handicapped 1 minute per 100 rating points with a maximum of 3 minutes deducted. When you play with one 1 minute physical ability becomes a huge factor. If you are not fast enough to move a piece while your opponent is reaching for his clock, and then hit your clock near ...

In the pre-2014 FIDE Laws of Chess article 10 said this: Article 10: Quickplay Finish 10.1 A ‘quickplay finish’ is the phase of a game when all the (remaining) moves must be made in a limited time. 10.2 If the player, having the move, has less than two minutes left on his clock, he may claim a draw before his flag falls. He shall summon the ...

There are several things to note: Computer ratings are inaccurate because there are so few serious games played between humans and computers that can be used to tune the ratings. Then the rest of the computer ratings are derived from computer v computer games. So it's 2200 plus or minus an error margin that could be hundreds of points. I have no idea where ...

The period before 2001 is documented on the Olimpbase site. The period from 2001 on is documented on the FIDE rating site. To find the details for pre-2001 go to the Olimpbase site and about a third of the way down on the right hand side under "PLAYERS & TEAMS" click on "Elo lists 1971-2001". To find the details for 2001 and after go to the FIDE rating ...

Late to the party, but while Anand losing to a guy, who was rated 400 points below him was, clearly, a huge upset; an IM, who was over 2400 at one point, and 2368 when that game was played is definitely strong enough to take advantage if Anand makes an error. This still probably beats all upsets I have ever heard of. In the first round, GM John Fedorowicz, ...

It seems that rankade, our ranking system for sports, games, and more, fits your needs. It's free to use and it's designed to manage rankings (and stats, including matchup stats, and more) for small to large groups of players. Rankade doesn't use Elo, but its algorithm (called ree algorithm), although more complex (here's a comparison between most known ...

There are two alternative rating systems - Glick/Glicko-2 and EloRater. I believe the author of EloRater is a member of this site - @JimGarner. You could try contacting him directly.

If you're unrated, you don't really have an expected score. How can anything be expected when your rating is totally unknown? But the win expectancy table is sometimes used in reverse, to calculate the rating of an unrated player based on the actual score. There are actually a few different formulas that might be used to determine your initial rating, ...
