Die Wertungszahlen (Ratings) der FIDE sind ein Gradmesser für die Spielstärke von Schachspielern. Mathematischer Hintergrund ist die Normalverteilung (Gauß'sche Glockenkurve). Untersuchungen von Prof. Arpad Elo führten in den er Jahren dazu, daß die FIDE die Ratingzahlen als Wertungssystem einsetzte. Häufig werden deshalb die Ratingzahlen auch als "Elo-Zahlen" . Der Umfang einer Elo-Klasse beträgt jeweils genau Punkte. Dabei beträgt die Gewinnerwartung für den stärkeren der beiden Spieler genau 75 Prozent. Wenn somit beispielsweise der fiktive Spieler A über einen Elo von verfügt und gegen den ebenfalls fiktiven Spieler B eine Partie bestreitet, dann beträgt seine Gewinnerwartung genau 75 Prozent.

I do agree that ratings seem a bit lower on lichess than on other websites, and actually I find this system much more stable. I am just over on FIDE elo and about the same on lichess (~ classical, ~ bullet). I have to say that it is the only place where I got a ranking reasonably near to my real ranking. Cheater mag niemand und eine Manipulation der ELO-Wertung verschafft dir keine Belohnungen zum Saisonende (und die will jeder haben!) Meister+ Spieler, die die Meister-Klasse oder höher erreicht haben, können sich ein Spiel gutschreiben lassen, um es am letzten Tag zu nutzen – und das sollten sie auch tun!. 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. Die Elo-Zahl ist eine Wertungszahl, die die Spielstärke von Schach- und Gospielern beschreibt. Das Konzept wurde inzwischen für verschiedene weitere​. Die Elo-Zahl ist eine Wertungszahl, die die Spielstärke von Schach- und Gospielern beschreibt. Das Konzept wurde inzwischen für verschiedene weitere Sportarten adaptiert. Ausgehend vom Bradley-Terry Modell – benannt nach R. A. Bradley und M. E. Wertungszahlen im Schach sollen die Spielstärke von Schachspielern bewerten. Elo-Zahlen des Weltschachverbands werden allerdings erst seit In verschiedenen Zwei-Personen-Spielen (Go, Schach, Backgammon) hat die sogenannte Elo-Zahl bereits eine große Bedeutung für die Bewertung der.

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. Around there was only one active player Anatoly Karpov with a rating this high.

In Viswanathan Anand was only the 8th player in chess history to reach the mark at that point of time. The current benchmark for elite players lies beyond One possible cause for this inflation was the rating floor, which for a long time was at , and if a player dropped below this they were stricken from the rating list.

As a consequence, players at a skill level just below the floor would only be on the rating list if they were overrated, and this would cause them to feed points into the rating pool.

By July it had increased to In a pure Elo system, each game ends in an equal transaction of rating points.

If the winner gains N rating points, the loser will drop by N rating points. This prevents points from entering or leaving the system when games are played and rated.

However, players tend to enter the system as novices with a low rating and retire from the system as experienced players with a high rating.

Therefore, in the long run a system with strictly equal transactions tends to result in rating deflation. In , the USCF acknowledged that several young scholastic players were improving faster than the rating system was able to track.

As a result, established players with stable ratings started to lose rating points to the young and underrated players.

Several of the older established players were frustrated over what they considered an unfair rating decline, and some even quit chess over it.
