time control
In competitive chess, each player has a given time to make her/his moves. Several different time control methods exist. In the most simple case, a player has a fixed time to make all her/his moves. In time controls with increments or time-delay, some time is added to the clock after each move. In over-the-board chess events, players often have a fixed time to finish the first x moves of the game and get additional time after that.
