What is a chess clock?
A chess clock is a specialized clock that has two time displays. They are attached to each other and wired so that only one can run at a time. When the word “clock ” is used in a chess tournament or in play, it refers to just one of the two displays.
When is a chess clock used?
Chess clocks are used almost exclusively in tournament play. Many chess clubs will also use chess clocks in preparation for tournament play. In casual or recreational play, very few people actually use chess clocks, as there are a wide range of rules associated with their use. Chess clocks help to keep the game moving at an appropriate speed.
What are the rules of a chess clock?
There are many rules associated with the use of a chess clock, including who starts and stops the clock, when it is used, and so forth. The following are some of these rules:
•The arbiter of the chess game decides where the chess clock is placed.
•When the game is to begin, the arbiter starts the clock of the player with the white pieces.
•Each clock has a flag. When the time for each move expires, the flag falls.
•Players are not allowed to start their own clocks. At the end of a move, the player stops his own clock and then starts the clock of his opponent.
•The move is not considered complete until the player has stopped his clock.
•Players have to use the same hand to stop their clocks as they use for making their moves.
•Players are not allowed to keep their finger on the clock’s button or to “hover ” over it.
•If the player doesn’t complete the set number of moves in the allotted time, he or she loses the game. The number of moves and the allotted amount of time are determined before the game begins. The exception to this rule states that a draw may be called if the arbiter determines the player can’t put his opponent in checkmate within a series of legal moves.
•In the event the game must be interrupted, it is the arbiter’s job to stop the clocks. However, a player is allowed to stop the clocks if he or she is taking up an issue with the arbiter. It is also the arbiter’s job to determine when the clocks are to be started again.
•In the event that both flags fall (allotted time for the move expires) and there is no way to determine which fell first, the game continues and neither player is penalized.
•If a player does not use all of his time in his move, the time saved during this period is added to his time available for the next period.
