context_page_description: The rules of chess are rules governing the play of the game of chess. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from place to place. Today, the standard rules are set by FIDE, the international governing body for chess. Slight modifications are made by some national organizations for their own purposes. There are variations of the rules for fast chess, correspondence chess, online chess, and Chess960.
  Chess is a two-player board game using a chessboard and sixteen pieces of six types for each player. Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king. Games do not necessarily end in checkmate; players often resign if they believe they will lose. A game can also end in a draw in several ways.
  Besides the basic moves of the pieces, rules also govern the equipment used, time control, conduct and ethics of players, accommodations for physically challenged players, and recording of moves using chess notation.
context_section_description: Each square of the chessboard is identified with a unique pair of a letter and a number. The vertical files are labeled a through h, from White's left (i.e. the queenside) to White's right. Similarly, the horizontal ranks are numbered from 1 to 8, starting from the one nearest White's side of the board. Each square of the board, then, is uniquely identified by its file letter and rank number. The white king, for example, starts the game on square e1. The black knight on b8 can move to a6 or c6.
  In formal competition, each player is obliged to record each move as it is played in a chess notation in order to settle disputes about illegal positions, overstepping time control, and making claims of draws by the fifty-move rule or repetition of position. Algebraic chess notation is the accepted standard for recording games today. There are other systems such as ICCF numeric notation for international correspondence chess and the obsolete descriptive chess notation. The current rule is that a move must be made on the board before it is written on paper or recorded with an electronic device.
  Both players should indicate offers of a draw by writing "=" at that move on their score sheet (Schiller 2003:27). Notations about the time on the clocks can be made. If a player has less than five minutes left to complete all of their moves, they are not required to record the moves (unless a delay of at least thirty seconds per move is being used). The score sheet must be made available to the arbiter at all times. A player may respond to an opponent's move before writing it down (Schiller 2003:25–26).
