So, what exactly is ELO Rating?

The ELO rating system is a method for calculating the relative skill levels of players in two-player games like chess. It is named after its founder, Arpad Elo, a Hungarian-American physics professor.

Each player has a numerical rating that represents their playing strength based on game results. Higher ratings indicate stronger players.

History and Origin of ELO Rating

The ELO rating system was developed in the late 1950s by Arpad Elo, a professor of physics at Marquette University. It was originally intended for rating players in games with a fixed scoring system like chess and go.

The system was adopted by the World Chess Federation (FIDE) in 1970 and has since become the standard for rating chess players worldwide.

Why is ELO Rating important?

The ELO rating system provides an objective way to compare the skills of chess players across different regions and levels. It allows tournament organizers to seed players appropriately and match competitors of similar strengths.

Ratings also serve as benchmarks for players to track their improvement over time.

Examples of ELO Rating

A beginner may have an ELO rating around 800. Club players typically range from 1000-1600. The highest ratings belong to elite grandmasters like Magnus Carlsen (2868 peak rating). Any rating over 2500 is considered super grandmaster strength.

Variations of ELO Rating

While FIDE uses the standard ELO system, some national chess federations like the United States Chess Federation (USCF) use slightly modified versions with different rating floors, K-factors, and formulas for calculating ratings.

How to get an ELO Rating

Players’ ratings change after every rated game based on the rating difference between opponents and the actual game result compared to the expected statistical outcome.

Winning against a higher-rated player yields more rating points than an expected win.

Famous examples of ELO Rating

Garry Kasparov achieved a peak FIDE rating of 2851, one of the highest ever. Bobby Fischer’s ‘peak’ rating of 2785 in 1972 was retrospectively inflated to 2900+ using modern calculations. Magnus Carlsen has the current highest rating at 2868.
