Fast chess (also known as speed chess) is a variation of chess in which each side is given less time to make a move than under normal tournament time controls. This means that each player will have less than 120 minutes at his or her disposal, based on a 60-move game, and sometimes considerably less than this. Fast chess can be further subdivided, by decreasing time controls, into rapid chess, blitz chess and bullet chess. Armageddon is a particular variation in which different rules apply for each of the two players.
