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. The World Chess Federation FIDE sets a single time control for all major FIDE events according to the handbook: 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. Exceptions can be made, though the Candidates tournaments for the World Championship have been played at 120 minutes for 40 moves, followed by 60 minutes for 20 moves, followed by 15 minutes for the rest of the game, with a 30-second increment starting on move 61.〔(【引用サイトリンク】title=Rules & regulations for the Candidates Tournament of the FIDE World Championship cycle 2011-2013 )〕 ==Classification== 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.〔(Instructions )〕 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. 'Lightning' is the quickest limit, then 'blitz'. Chess has an 'active' category after this. In chess, Lightning refers to 3 minutes or below, blitz refers to between 4 and 15 minutes, and Active is between 15 and 30. By way of contrast, for Go anything under twenty minutes could be considered blitz. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「time control」の詳細全文を読む スポンサード リンク
