Flag-Fall

A game played under time control will end as a loss for a player who uses up all the time allotted on the player's clock, which is called flag-fall, unless the opponent has no possibility of effecting checkmate. There are different types of time control. A player may have a fixed amount of time for the entire game, or may have to make a certain number of moves within a specified time. Also, a small increment of time may be added for each move made.
