<P> A time control is a mechanism in the tournament play of almost all two - player board games so that each round of the match can finish in a timely way and the tournament can proceed . Time controls are typically enforced by means of a game clock . Time pressure (or time trouble or zeitnot) is the situation of having very little time on a player's clock to complete their remaining moves . </P> <P> In the case of chess, the World Chess Federation FIDE has a single, classical time control for most of its major events, 90 minutes for the first 40 moves, followed by 30 minutes for the rest of the game, with an addition of 30 seconds per move starting from move one . The Candidates tournament and the World Championship are currently played at 100 minutes for 40 moves, followed by 50 minutes for 20 moves, followed by 15 minutes for the rest of the game, with a 30 - second increment starting from move one . Also, FIDE formulates different time controls for fast chess . </P> <P> The amount of time given to each player to complete their moves will vary from game to game . However most games tend to change the classification of tournaments according to the length of time given to the players . Shorter time limits, which do not afford due consideration to moves, are afforded a lesser degree of importance . Indeed, shorter limits are normally given special names to distinguish them . </P>
