Chess Ratings: A Deep DiveIf 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. 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 desperaweb.com I guess in some time format. Then randomly divide them all into 2 groups. The Automated Chess Rating Utility Get Your Elo Rating Here! Use this test to get an estimate of your Elo rating: study each diagram for no more than five minutes, then input your move. At the bottom of the page you can click and immediately obtain your Elo rating estimate. Live Chess Ratings for players with Elo ratings of You may review the latest games played by top players, download their games (PGN), follow big chess tournaments, and get a widget for Top 10 chess players in the world. Also included are FIDE blitz and rapid ratings, twitter @chess, and live games. 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.In turn, when the lowerrated player wins, this achievement is considered much more significant, and that player's reward is more points added to their rating.
The higherrated player, though, is penalized accordingly. To determine the exact amount of points a player would win or lose after a game, several complex mathematical calculations are needed.
Do not worry, though, because Chess. After every rated game, your rating is updated instantly. Almost all chess federations and websites around the world use the Elo rating system or a variation of it, such as the Glicko system.
This measurement of a player's strength has become the standard in the chess world, so it is the easiest way to assess someone's level of play.
In addition, the Elo system is a statistical model that operates solely based on the outcomes of the games played.
As a result, this measurement is more precise than merely judging a player's strength based on subjective and arbitrary elements of the game.
It has enabled fascinating insights into comparing the relative strength of players from completely different generations, such as the ability to compare Capablanca with Kasparov for example.
However, in some cases ratings can discourage game activity for players who wish to "protect their rating".
IIn these examples, the rating "agenda" can sometimes conflict with the agenda of promoting chess activity and rated games. Some of the clash of agendas between game activity, and rating concerns is also seen on many servers online which have implemented the Elo system.
For example, the higher rated players, being much more selective in who they play, results often in those players lurking around, just waiting for "overvalued" opponents to try and challenge.
Such players because of rating concerns, may feel discouraged of course from playing any significantly lower rated players again for rating concerns.
The agenda of points scoring can interfere with playing with abandon, and just for fun. 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 tiebreaking 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 handpick your opponents is not present in OverTheboard 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 overrated opponents, newentrants 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 Kfactor to the established player if they do win against a new rating entrant.
The Kfactor 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 "autopairing" 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 higherrated participants, who may face very stiff opposition from players below for example.
This is a separate rating in itself, and is under "1minute" and "5minute" 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 Kfactor, 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 "Kfactor" used. If the Kfactor 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.
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 derive a number to represent that player's skill. Performance can only be inferred from wins, draws and losses.
Therefore, if a player wins a game, they are assumed to have performed at a higher level than their opponent for that game. Conversely, if the player loses, they are 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 did not specify exactly how close two performances ought to be to result in a draw as opposed to a win or loss.
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 highestrated 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 nonscholastic is , the average player is , and professional level is The Kfactor , 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 USCFsanctioned 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.
