Most people associate Elo with the game of chess — it is used extensively by national chess federations, online chess websites, and even by FIDE (the governing body of international chess. 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 novascotiabluegrass.com I guess in some time format. Then randomly divide them all into 2 groups. Arpad Elo was a master-level chess player and an active participant in the United States Chess Federation (USCF) from its founding in The USCF used a numerical ratings system, devised by Kenneth Harkness, to allow members to track their individual progress in terms other than tournament wins and losses.

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. Play and find out. No, a sticky is a technical term referring to a forum topic which is always at the top, listed before even the most recent topic.

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 ! As of April , the Hydra supercomputer was possibly the strongest "over the board" chess player in the world; its playing strength is estimated by its creators to be over on the FIDE scale.

This is consistent with its six game match against Michael Adams in in which the then seventh-highest-rated player in the world only managed to score a single draw.

However, six games are scant statistical evidence and Jeff Sonas suggested that Hydra was only proven to be above by that single match taken in isolation.

On a slightly firmer footing is Rybka. As of January , Rybka is rated by several lists within , depending on the hardware it is run on and the version of software used.

Without such calibration, different rating pools are independent, and can only be used for relative comparison within the pool.

The primary goal of Elo ratings is to accurately predict game results between contemporary competitors, and FIDE ratings perform this task relatively well.

A secondary, more ambitious goal is to use ratings to compare players between different eras. It would be convenient if a FIDE rating of meant the same thing in that it meant in If the ratings suffer from inflation , then a modern rating of means less than a historical rating of , while if the ratings suffer from deflation , the reverse will be true.

When a player's actual tournament scores exceed their expected scores, the Elo system takes this as evidence that player's rating is too low, and needs to be adjusted upward.

Similarly, when a player's actual tournament scores fall short of their expected scores, that player's rating is adjusted downward. Elo's original suggestion, which is still widely used, was a simple linear adjustment proportional to the amount by which a player overperformed or underperformed their expected score.

The formula for updating that player's rating is. This update can be performed after each game or each tournament, or after any suitable rating period.

An example may help to clarify. Suppose Player A has a rating of and plays in a five-round tournament. He loses to a player rated , draws with a player rated , defeats a player rated , defeats a player rated , and loses to a player rated The expected score, calculated according to the formula above, was 0.

Note that while two wins, two losses, and one draw may seem like a par score, it is worse than expected for Player A because their opponents were lower rated on average.

Therefore, Player A is slightly penalized. New players are assigned provisional ratings, which are adjusted more drastically than established ratings.

The principles used in these rating systems can be used for rating other competitions—for instance, international football matches. See Go rating with Elo for more.

The first mathematical concern addressed by the USCF was the use of the normal distribution. They found that this did not accurately represent the actual results achieved, particularly by the lower rated players.

Instead they switched to a logistic distribution model, which the USCF found provided a better fit for the actual results achieved.

The second major concern is the correct "K-factor" used. If the K-factor coefficient is set too large, there will be too much sensitivity to just a few, recent events, in terms of a large number of points exchanged in each game.

And if the K-value is too low, the sensitivity will be minimal, and the system will not respond quickly enough to changes in a player's actual level of performance.

Elo's original K-factor estimation was made without the benefit of huge databases and statistical evidence.

Sonas indicates that a K-factor of 24 for players rated above may be more accurate both as a predictive tool of future performance, and also more sensitive to performance.

Certain Internet chess sites seem to avoid a three-level K-factor staggering based on rating range. The USCF which makes use of a logistic distribution as opposed to a normal distribution formerly staggered the K-factor according to three main rating ranges of:.

Currently, the USCF uses a formula that calculates the K-factor based on factors including the number of games played and the player's rating.

The K-factor is also reduced for high rated players if the event has shorter time controls. FIDE uses the following ranges: [20].

FIDE used the following ranges before July [21]. The gradation of the K-factor reduces ratings changes at the top end of the rating spectrum, reducing the possibility for rapid ratings inflation or deflation for those with a low K-factor.

This might in theory apply equally to an online chess site or over-the-board players, since it is more difficult for players to get much higher ratings when their K-factor is reduced.

In some cases the rating system can discourage game activity for players who wish to protect their rating.

Beyond the chess world, concerns over players avoiding competitive play to protect their ratings caused Wizards of the Coast to abandon the Elo system for Magic: the Gathering tournaments in favour of a system of their own devising called "Planeswalker Points".

A more subtle issue is related to pairing. When players can choose their own opponents, they can choose opponents with minimal risk of losing, and maximum reward for winning.

In the category of choosing overrated opponents, new entrants to the rating system who have played fewer than 50 games are in theory a convenient target as they may be overrated in their provisional rating.

The ICC compensates for this issue by assigning a lower K-factor to the established player if they do win against a new rating entrant. The K-factor is actually a function of the number of rated games played by the new entrant.

Therefore, Elo ratings online still provide a useful mechanism for providing a rating based on the opponent's rating. Its overall credibility, however, needs to be seen in the context of at least the above two major issues described — engine abuse, and selective pairing of opponents.

The ICC has also recently introduced "auto-pairing" ratings which are based on random pairings, but with each win in a row ensuring a statistically much harder opponent who has also won x games in a row.

With potentially hundreds of players involved, this creates some of the challenges of a major large Swiss event which is being fiercely contested, with round winners meeting round winners.

This approach to pairing certainly maximizes the rating risk of the higher-rated participants, who may face very stiff opposition from players below , for example.

This is a separate rating in itself, and is under "1-minute" and "5-minute" rating categories. Maximum ratings achieved over are exceptionally rare.

An increase or decrease in the average rating over all players in the rating system is often referred to as rating inflation or rating deflation respectively.

For example, if there is inflation, a modern rating of means less than a historical rating of , while the reverse is true if there is deflation.

Using ratings to compare players between different eras is made more difficult when inflation or deflation are present. See also Comparison of top chess players throughout history.

It is commonly believed that, at least at the top level, modern ratings are inflated. For instance Nigel Short said in September , "The recent ChessBase article on rating inflation by Jeff Sonas would suggest that my rating in the late s would be approximately equivalent to in today's much debauched currency".

By when he made this comment, would only have ranked him 65th, while would have ranked him equal 10th. It has been suggested that an overall increase in ratings reflects greater skill.

The advent of strong chess computers allows a somewhat objective evaluation of the absolute playing skill of past chess masters, based on their recorded games, but this is also a measure of how computerlike the players' moves are, not merely a measure of how strongly they have played.

The number of people with ratings over has increased. Wei Yi Wei Yi. Vidit Vidit. Andreikin Andreikin. Svidler Svidler.

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.
