A method of discouraging players from taking an excessively long time to act. When someone calls the clock, the player has a set amount of time in which to make up his mind; if he fails to do so, his hand is immediately declared dead. In tournament play, a common rule is that if a player takes too long and no one calls the clock, the dealer or floor personnel will automatically do so.
