Fast chess is a type of chess in which each player is given less time to consider their moves than normal tournament time controls allow. Fast chess is subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a particular variation of fast chess in which different rules apply for each of the two players. The top ranked 2021 world rapid chess player is Magnus Carlsen from Norway, who is also the top ranked classical chess player.
