Elo Chess

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 players would be expected to win based on comparisons of their ratings to those of their opponents.

The ratings of a player who won more games than expected would be adjusted upward, while those of a player who won fewer than expected would be adjusted downward.

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

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. On the other hand, the computational simplicity of the Elo system has proven 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 their next officially published rating will be, which helps promote a perception that the ratings are fair.

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. 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.

I am playing in chess. I want to know my rating because I am still unrated. For this I may please be guided what steps I have to take. Will it be possible to know my rating without being a member?

If yes, I may please be intimated how and if no, I want to know how I can get the membership? Select "rated" rather than "unrated" from the drop down menu when you start a new game.

You don't need to become a premium member. My rating on chess. I think numbers are inflated here just because of the fact it is the internet and there will always be ways to cheat using computers or help from friends ect.

But, in my head, if you play completely legit, like we all should and do, and you can keep up with other high level players and cheaters, ect, then I dont see this rating system being too different then others, especially at higher levels.

My online rating ils a little better than my real rating on chess. For most of us, the "Holy Grail" is 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.

This system calculates the probable outcome of a person's games against other players. Calculating the probable outcome of chess games is one of the fascinating aspects of this rating system: it takes into consideration the fluctuations in a player's performance.

From time to time, we all have bad days when we play poorly. Even when we are at our best, we can still slip up and make a game-losing blunder.

Lower-rated players can still beat someone who is rated higher than them, and the Elo system calculates the probability of that happening.

However, if both players face each other in a match of multiple games, the player with the higher rating probably wins most of the games.

Interesting from the perspective of preserving high Elo ratings versus promoting rated game activity is a recent proposal by British Grandmaster John Nunn regarding qualifiers based on Elo rating for a World championship model.

Nunn highlights in the section on "Selection of players", that players not only be selected by high Elo ratings, but also their rated game activity.

Nunn clearly separates the "activity bonus" from the Elo rating, and only implies using it as a tie-breaking mechanism. The Elo system when applied to casual online servers has at least two other major practical issues that need tackling when Elo is applied to the context of online chess server ratings.

These are engine abuse and selective pairing. The first and most significant issue is players making use of chess engines to inflate their ratings. This is particularly an issue for correspondence chess style servers and organizations, where making use of a wide variety of engines within the same game is entirely possible.

This would make any attempts to conclusively prove that someone is cheating quite futile. Blitz servers such as the Free Internet Chess Server or the Internet Chess Club attempt to minimize engine bias by clear indications that engine use is not allowed when logging on to their server.

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.

Such a luxury of being able to hand-pick your opponents is not present in Over-The-board Elo type calculations, and therefore this may account strongly for the ratings on the ICC using Elo which are well over In the category of choosing over-rated opponents, new-entrants to the rating system who have played less 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. Elo therefore must be treated as a bit of fun when applied in the context of online server ratings.

Indeed the ability to choose one's own opponents can have great fun value also for spectators watching the very highest rated players.

For example they can watch very strong GM's challenge other very strong GMs who are also rated over for example.

Such opposition which the highest level players online would play in order to maintain their rating, would often be much stronger opponents than if they did play in an Open tournament which is run by Swiss pairings.

Additionally it does help ensure that the game histories of those with very high ratings will often be with opponents of similarly high level ratings.

Elo ratings online therefore still provides 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 in recent times 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.

There are three main mathematical concerns relating to the original work of Professor Elo, namely the correct curve, the correct K-factor, and the provisional period crude calculations.

They found that this did not accurately represent the actual results achieved by particularly the lower rated players.

Instead they switched to a logistical distribution model, which seemed to provide 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 winning, losing or drawing, in terms of the large number of points exchanged.

Too low a K-value, and the sensitivity will be minimal, and it would be hard to achieve a significant number of points for winning, etc.

Elo's original K-factor estimation, was based 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 have staggered the K-factor according to three main rating ranges of:.

In over-the-board chess, the staggering of K-factor is important to ensure minimal inflation at the top end of the rating spectrum. In theory, it would make it harder for players to get the much higher ratings, if their K-factor sensitivity was lessened from 32 to 16 for example, when they get over rating.
