Fast chess

Fast chess, also known as speed chess, is a type of chess in which each player is given less time to consider their moves than classical chess 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.

As of July 2024, the top-ranked blitz chess player in the open section is Magnus Carlsen from Norway, who is also the top-ranked classical chess player, reigning World Rapid Chess Champion, as well as the reigning World Blitz Chess Champion. Carlsen is also the top-ranked rapid chess player.
