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.
Chess is a board game for two players. It is played on a square board, made of 64 smaller squares, with eight squares on each side. Each player starts with sixteen pieces: eight pawns, two knights, two bishops, two rooks, one queen and one king. The goal of the game is for each player to try and checkmate the king of the opponent. Checkmate is a threat ('check') to the opposing king which no move can stop.
