Is a 3300 Blitz Rating Even Possible on countryfurniturebc.com?

A chess player is "one pawn stronger" than another player if he can give a pawn and have an expected score of 0. A ranking system based on material odds is perfectly possible: the strength of a player could be described by the material odds needed against a chess master, and actually that was the way chess strength was described in the midth century according to the history section of Handicap chess.

How do we translate between Elo and material odds? The first thing to realize is that the number of Elo points equivalent to one pawn varies with the strength of the players.

Some estimates by GM Larry Kaufman are given in the "Rating equivalent" section of the article linked above. More data points are given by matches played with material odds or draw odds between two human players or between a human and a computer, some of which are discussed at the end of the "History" section.

I fitted a curve as best as I could and below is a graph of the result. The calculator applies this curve to display material odds when given two Elo ratings.

Handicap stones in Go are the rough equivalent of material odds in Chess since both are modifications of the start position so that both players have equal chances of winning.

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 USCF uses a modification of the Elo system, where the K factor varies and there are bonus points for superior performance in a tournament. First, the difference in rating is calculated for each other player, subtracting the other player's rating from Portisch's rating.

Then the expected score against each player is determined from a table, based on this rating difference. For instance, one opponent was Vlastimil Hort , who was rated at The rating difference of 35 gave Portisch an expected score of 0.

The expected score is summed for each opponent, giving Portisch a total expected score of 9. Then the formula is:.

Elo devised a linear approximation to his full system. With that method, a player's new rating is.

Elo — The Glicko system was invented by Mark E. 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.

Melde dich ruhig mal an und mach mit! Wo würdest du bei so einem Turnier dastehen? Es gibt durchaus Blitzturniere mit 5 Minuten Bedenkzeit.

Elo once stated that the process of rating players was in any case rather approximate; he compared it to "the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind". The International Chess Federation, FIDE (Fédération Internationale des Échecs), awards several performance-based titles to chess players, up to and including the highly prized Grandmaster (GM) title. Titles generally require a combination of Elo rating and norms (performance benchmarks in competitions including other titled players).

The Elo rating system measures the relative strength of a player in some games, such as chess, compared to other players.
