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 grandotokiralama.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 grandotokiralama.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.

Novag Constellation Junior. Follow chess. Elo's original K-factor estimation, was based without the benefit of huge databases and statistical evidence. Topalov Topalov. See also: Hubbert curve. Elo therefore must be treated as a bit of fun when Ogame Ressourcen Rechner in the context of online server ratings. Meaning I have no way of finding out my "real" rating. I want to start studying chess and I feel it would be best to have an idea of my actual rating before I get too serious about it so as to know what level I am and thus study what is suggested for my skill level.

I have heard that chess. Currently I am rated around on chess. I feel much better than this and I think my endgame is my strong-point and I have a firm grasp on middle-game tactics, and have noticed a lot of my losses can be attributed to openings blunders or just overall lack of opening knowledge so I've begun to study openings, which I know most don't recommend for "beginners" which I am not, and have been playing chess since I was 5, but I realize I'm not a very strong player and I am dead-set on improving.

So I need to have an accurate idea of my rating so I can both study accordingly and see results which is key to improvement in anything.

So you're basing your study plan on a mysterious number so that you can filter out material that's correct for your level?

I don't see why you need a number to do that. Pursue material suitable for and if you find it too rudimentary, move to books recommended for the next rating class.

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.

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.

Another feature of this system is that the rating gap between the players dictates how many points they can win or lose. Since a much higher rated player is expected to win, they do not receive a lot of points for a victory against a player rated much lower.

Their opponent also does not lose a significant amount of points for the defeat. In turn, when the lower-rated player wins, this achievement is considered much more significant, and that player's reward is more points added to their rating.

The higher-rated 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.

Performance can't be measured absolutely; it can only be inferred from wins and losses. Ratings therefore have meaning only relative to other ratings.

Therefore, 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 of approximately 0.

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

When a player's actual tournament scores exceed his 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 his 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 his expected score.

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

An example may help 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 His expected score, calculated according 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 his opponents were lower rated on average.

Therefore he is slightly penalized. New players are assigned provisional ratings, which are adjusted more drastically than established ratings, and various methods none completely successful have been devised to inject points into the rating system so that ratings from different eras are roughly comparable.

The principles used in these rating systems can be used for rating other competitions—for instance, international football matches.

In general the Elo system has increased the competitive climate for chess and inspired players for further study and improvement of their 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 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 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.

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.
