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.
The king is the most valuable chess piece in a game of chess. It can move left, right, up, down or diagonally. It can only move one square at a time. When recording chess games, king is shortened to K. The object of the game is to checkmate (capture the king). If a player's king is attacked by an opponent's piece, it is called check. The player with the attacked king must move so that the king is no longer in check.
