The Elo rating system is a method for calculating the relative skill levels of players in two-player games such as chess and Go. Elo is often written in capital letters (ELO), but it is not an acronym. It is the family name of the system's creator, Arpad Elo (1903â1992), a Hungarian-born American physics professor. Elo was originally invented as an improved chess rating system although it is used in many games today.
Titles generally require a combination of Elo rating and norms (performance benchmarks in competitions including other titled players).Once awarded, FIDE titles are held for life, though a title may be revoked in exceptional circumstances.he title Grandmaster is awarded to outstanding chess players by FIDE. Apart from World Champion, Grandmaster is the highest title a chess player can attain. Once achieved, the title is generally held for life.
