Traditionally, competitive chess has been played with specified time limits. When chess first appeared in India around the seventh century AD, measuring time was a critical part of the game. Even before the World Chess Federation (FIDE) was established on July 20, 1924, the system of hour-glass timing was used.
Chess time controls refer to how much time a player receives to complete a game. Each player has an equal amount of time. Recently, I would theorize about five to eight years ago, speed chess (rapid, blitz and bullet ) became immensely popular. For some of the young, the shift from 90 minutes plus to 10 minutes plus, is attractive. However, I have my doubts about whether one’s chess abilities will get further refined.
