what is elo in chess
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 (1903â1992), a Hungarian-born American physics professor. Elo was originally invented as an improved chess rating system although it is used in many games today.
