he rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game.

A game can end in various ways besides checkmate: a player can resign, and there are several ways in which a game can end in a draw.
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.
