ELO rating does not show how smart you are, how well your memory is, how fast can you calculate chess variations or recognize chess patterns (it is a topic of a separate discussion, how well the IQ score reflects all of the above). Anyway, I started wondering about the following thought experiment. Say you took all the people with established elo on one site like say people who have played more than different people on sayulitawineshop.com I guess in some time format. Then randomly divide them all into 2 groups. The Elo rating system was officially adopted by the U.S. Chess Federation in and by FIDE in Many chess organizations and websites also use this system to rate players. On sayulitawineshop.com, we use a modified version of the Elo system called the Glicko system, which takes more variables into consideration to determine a player's rating. If you seem to average on live chess, chances are you can't be "better" than OTB standard, be it FIDE USCF or ELO. (the opposite is more likely, your OTB playing strength can be much worse!). Pursue material suitable for and if you find it too rudimentary, move to books recommended for the next rating class. Therefore, in the long run a system with strictly equal transactions tends to result in rating deflation.

Not Lotto Kosten science really: my weaknesses are for me to know and my opponents to find out. The Elo rating system was featured prominently in The Social Network during the algorithm scene where Mark Zuckerberg released Facemash. An Elo rating is a comparative rating only, and is valid only within the rating pool where it was established. Performance can't be measured absolutely; it can only be inferred from wins and losses. For women's tournaments, the categories are rating points lower, so a Category 1 is an average rating of to Bbq Sauce Bullseye, etc. Moreover, even within the simplified model, more efficient estimation techniques are Jackpot Spiele Kostenlos known. TotoScacco uses a modified Anleitung Siedler Von Catan rating system to rank the players of its guess-the-results game, where one has to predict the results of top chess events.

Although a player might perform significantly better or worse from one game to the next, Elo assumed that the mean value of the performances of any given player changes only slowly over time.

Elo thought of a player's true skill as the mean of that player's performance random variable. A further assumption is necessary, because chess performance in the above sense is still not measurable.

One cannot look at a sequence of moves and say, "That performance is Therefore, if a player wins a game, he is assumed to have performed at a higher level than his opponent for that game.

Conversely if he loses, he is assumed to have performed at a lower level. If the game is a draw, the two players are assumed to have performed at nearly the same level.

Elo waved his hands at several details of his model. For example, he did not specify exactly how close two performances ought to be to result in a draw rather than a decisive result.

And while he thought it likely that each player might have a different standard deviation to his performance, he made a simplifying assumption to the contrary.

To simplify computation even further, Elo proposed a straightforward method of estimating the variables in his model i.

One could calculate relatively easily, from tables, how many games a player is expected to win based on a comparison of his rating to the ratings of his opponents.

If a player won more games than he was expected to win, his rating would be adjusted upward, while if he won fewer games than expected his rating would be adjusted downward.

Moreover, that adjustment was to be in exact linear proportion to the number of wins by which the player had exceeded or fallen short of his expected number of wins.

From a modern perspective, Elo's simplifying assumptions are not necessary because computing power is inexpensive and widely available.

Moreover, even within the simplified model, more efficient estimation techniques are well known. Several people, most notably Mark Glickman, have proposed using more sophisticated statistical machinery to estimate the same variables.

In November , the Xbox Live online gaming service proposed the TrueSkill ranking system that is an extension of Glickman's system to multi-player and multi-team games.

On the other hand, the computational simplicity of the Elo system has proved to be one of its greatest assets. With the aid of a pocket calculator, an informed chess competitor can calculate to within one point what his next officially published rating will be, which helps promote a perception that the ratings are fair.

The USCF implemented Elo's suggestions in , and the system quickly gained recognition as being both fairer and more accurate than the Harkness system.

Elo's system was adopted by FIDE in Elo described his work in some detail in the book The Rating of Chessplayers, Past and Present , published in Subsequent statistical tests have shown that chess performance is almost certainly not normally distributed.

Weaker players have significantly greater winning chances than Elo's model predicts. However, in deference to Elo's contribution, both organizations are still commonly said to use "the Elo system".

Each organization has a unique implementation, and none of them precisely follows Elo's original suggestions. It would be more accurate to refer to all of the above ratings as Elo ratings, and none of them as the Elo rating.

Instead one may refer to the organization granting the rating, e. In the whole history of FIDE rating system, only 39 players to April , sometimes called "Super-grandmasters", have achieved a peak rating of or more.

However, due to ratings inflation, nearly all of these are modern players: all but two of these achieved their peak rating after Several chess computers are said to perform at a greater strength than any human player, although such claims are difficult to verify.

Computers do not receive official FIDE ratings. Matches between computers and top grandmasters under tournament conditions do occur, but are comparatively rare.

Also most computer players are software packages, making their playing strength and hence their rating dependent on the computer they are running on.

The Grand Master model K has an estimated Elo rating of ! He was a solid chess player himself, as you can see from this game he played against a young Bobby Fischer.

The Elo rating system was officially adopted by the U. Many chess organizations and websites also use this system to rate players. On Chess. He reached an impressive classical rating of in As of June , Carlsen is the highest-rated player for classical and rapid time controls and second in blitz behind GM Hikaru Nakamura.

Each player's Elo rating is represented by a number that reflects that person's results in previous rated games. After each rated game, their ratings are adjusted according to the outcome of the encounter.

While people usually think of the Elo rating system as a way of measuring a player's absolute strength, you should note that this is not the case.

Rinse and repeat. It isn't too hard. IT doesn't take too long to figure out what's over your head and what isn't. I don't see a phenomenal jump in the efficiency of your study-time by hunting down this mythical number and THEN filtering the quality of material flowing into your cranium Or better yet, taking a closer look at your lost games and having a strong-er player go over them with you.

My CFC rating used to about On here, my blitz rating fluctuates anywhere between and admittedly on the lower end right now.

Shivsky, thanks for your input and while I can't help but agree with your sentiments I do think there is some value to knowing how one ranks up with other players and because I am pursuing a stronger game I can't help but look to others for suggestions.

So yes I could figure out for myself what is and isn't beneficial for me to learn - whether it's too elementary or over my head, when starting out a study plan I'd rather take a tried and true r approach rather than follow my own unorganized study plan.

This helps me personally with staying on track rather than getting distracted and jumping from study topic to study topic and I can remain focused.

All in all, I'm not one to conform to trodding the beaten path, but at the same time I want to avoid going it freestyle on my own, and just wanted to better understand my skill level so I can plot my study accordingly.

That said, I'm not trying to "filter out" anything based on the number, but I'm trying to "filter out" the things based on what the number represents.

I am not following my number blindly, I know to take statistics with a grain of salt. Knowing where one stands against others can not be ignored when competing with others.

My best example of all of this would be if I asked members here on the forum what they recommend I study, the first question they'd ask, as information they'd need to base their answer on, would likely be my rating.

Fair enough As far as books go, there's the Novice Test in Danny Kopec's Test, Evaluate and Improve your Chess and the very comprehensive Igor Khelmnitsky Chess Rating Exam if you want to get a good approximation without actually playing a Federation rated tournament game.

The other way out is for you to post one of your losses in this thread and you'll find most of the decent folk here who play rated tournaments could size you up rather quickly.

FIDE tournements is 2 hours each player each game. There is alot of difference between both 5 mins and 3 days. You cant find your elo without playing in a elo rated tournement.

The USCF implemented Elo's suggestions in , [4] and the system quickly gained recognition as being both fairer and more accurate than the Harkness rating system.

Subsequent statistical tests have suggested that chess performance is almost certainly not distributed as a normal distribution , as weaker players have greater winning chances than Elo's model predicts.

Significant statistical anomalies have also been found when using the logistic distribution in chess. The table is calculated with expectation 0, and standard deviation The normal and logistic distribution points are, in a way, arbitrary points in a spectrum of distributions which would work well.

In practice, both of these distributions work very well for a number of different games. Each organization has a unique implementation, and none of them follows Elo's original suggestions precisely.

It would be more accurate to refer to all of the above ratings as Elo ratings and none of them as the Elo rating. Instead one may refer to the organization granting the rating.

There are also differences in the way organizations implement Elo ratings. For top players, the most important rating is their FIDE rating.

FIDE has issued the following lists:. A list of the highest-rated players ever is at Comparison of top chess players throughout history.

Performance rating is a hypothetical rating that would result from the games of a single event only. Some chess organizations [ citation needed ] use the "algorithm of " to calculate performance rating.

According to this algorithm, performance rating for an event is calculated in the following way:. This is a simplification, but it offers an easy way to get an estimate of PR performance rating.

Permanent Commissions, A simplified version of this table is on the right. FIDE classifies tournaments into categories according to the average rating of the players.

Each category is 25 rating points wide. Category 1 is for an average rating of to , category 2 is to , etc. For women's tournaments, the categories are rating points lower, so a Category 1 is an average rating of to , etc.

The top categories are in the table. FIDE updates its ratings list at the beginning of each month. In contrast, the unofficial "Live ratings" calculate the change in players' ratings after every game.

The unofficial live ratings of players over were published and maintained by Hans Arild Runde at the Live Rating website until August Another website, chess.

Rating changes can be calculated manually by using the FIDE ratings change calculator. In general, a beginner non-scholastic is , the average player is , and professional level is The K-factor , in the USCF rating system, can be estimated by dividing by the effective number of games a player's rating is based on N e plus the number of games the player completed in a tournament m.

The USCF maintains an absolute rating floor of for all ratings. Thus, no member can have a rating below , no matter their performance at USCF-sanctioned events.

However, players can have higher individual absolute rating floors, calculated using the following formula:. Higher rating floors exist for experienced players who have achieved significant ratings.

Such higher rating floors exist, starting at ratings of in point increments up to , , , A rating floor is calculated by taking the player's peak established rating, subtracting points, and then rounding down to the nearest rating floor.

Under this scheme, only Class C players and above are capable of having a higher rating floor than their absolute player rating. All other players would have a floor of at most There are two ways to achieve higher rating floors other than under the standard scheme presented above.

If a player has achieved the rating of Original Life Master, their rating floor is set at The achievement of this title is unique in that no other recognized USCF title will result in a new floor.

Pairwise comparisons form the basis of the Elo rating methodology. Performance is not measured absolutely; it is inferred from wins, losses, and draws against other players.

Players' ratings depend on the ratings of their opponents and the results scored against them. The difference in rating between two players determines an estimate for the expected score between them.

Both the average and the spread of ratings can be arbitrarily chosen. Elo suggested scaling ratings so that a difference of rating points in chess would mean that the stronger player has an expected score which basically is an expected average score of approximately 0.

A player's expected score is their probability of winning plus half their probability of drawing. Thus, an expected score of 0.

The probability of drawing, as opposed to having a decisive result, is not specified in the Elo system. Instead, a draw is considered half a win and half a loss.

In practice, since the true strength of each player is unknown, the expected scores are calculated using the player's current ratings as follows.

It then follows that for each rating points of advantage over the opponent, the expected score is magnified ten times in comparison to the opponent's expected score.
