Editing Time control (section)

==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.<ref>{{cite web|url=http://gemma.ujf.cas.cz/~cieply/GO/format.html#CLASS|title=Instructions|website=gemma.ujf.cas.cz|access-date=9 May 2018|url-status=live|archive-url=https://web.archive.org/web/20161220072413/http://gemma.ujf.cas.cz/~cieply/GO/format.html#CLASS|archive-date=20 December 2016}}</ref>

In [[chess]], various classification schemes are used. [[FIDE]] defines time controls based on the sum of the amount of time allotted to each player, plus the [[#Increment|increment]] per move times 60. Any time control in which this sum is more than 60 minutes (120 minutes at the master level) is '''classical''';<ref name="fide-classical">{{cite web |title=FIDE Rating Regulations effective from 1 January 2022 |url=https://handbook.fide.com/chapter/B022022 |publisher=FIDE |quote=''For a game to be rated each player must at the start of the tournament have the following minimum periods in which to complete all the moves, assuming the game lasts 60 moves.

Where at least one of the players in the game has a rating 1800 or higher, each player must have a minimum of 90 minutes.

In addition, both sites have a separate '''bullet''' category for games in which less than 3 minutes are given to each player; Lichess additionally has '''hyperbullet''' (≤30s) and '''ultrabullet''' (≤15s) categories.
 
In [[Go (board game)|Go]], anything under twenty minutes could be considered "blitz".
