[edit] Old talk
Would it be possible to put a picture of an Ing Clock on this page? This would help augment the byo yomi passage and allows the introduction of the Ing Overtime Rules as used in Go Tournaments.--ZincBelief 12:19, 21 November 2006 (UTC)
This article is rather unstructured at the moment. What would be the best way to mould it into a format that can best illustrate and explain the types of time control used over many types of games? Section on speed Blitz, Normal, Especially Long is simple to write. For time control methodology we probably need to seperate into types
- Sudden Death: Obvious
- Overtime Forms: Canadian Byoyomi and Japanese Byoyomi, in Go ; Fide Time Limits in Chess.
- Compensation Forms: Fischer, Bronstein time
- Penalty Forms: Ing, Scrabble

Well how about this....
A time control is imposed on 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, time trouble or zeitnot is the situation of having very little time on one's clock to complete one's remaining moves.
[edit] 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[1]. 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. As an example, for go anything under 20 minutes can be considered blitz, while Chess generally considers something below 10 minutes to be in this category.
[edit] Methodology
The exact approach to using a game clock to regulate games varies considerably.
[edit] Sudden Death
This is the simplest methodology. Once a player's main time expires he loses the game.
[edit] Overtime Formats
Here the game time is seperated into two basic domains. The main time, and the overtime. To switch between the two requires some trigger event. For example in Chess reaching a fixed number of moves will trigger the gain of a fixed amount of bonus time. In go two common forms are
- Canadian Byo-yomi:
After using all of his/her main time, a player must make a certain number of moves within a certain period of time — for example, twenty moves within five minutes. Typically, players stop the clock, and the player in overtime sets his/her clock for the desired interval, counts out the required number of stones and sets the remaining stones out of reach, so as not to become confused. (Some game clocks, notably the Ing clock, do not permit this option.) If twenty moves are made in time, the timer is reset to five minutes again. This is written as <main time> + <number of moves to be completed in each byo-yomi time period> in <byo-yomi time period>. [2] If the time period expires without the required number of stones having been played, then the player has lost on time. In Progressive Byo-yomi the required rate of play alters as we progress through additional overtime periods. [3]
- Standard Byoyomi:
After the main time is depleted, a player has a certain number of time periods (typically around thirty seconds). After each move, the number of time periods that the player took (possibly zero) is subtracted. For example, if a player has three thirty-second time periods and takes thirty or more (but less than sixty) seconds to make a move, he loses one time period. With 60-89 seconds, he loses two time periods, and so on. If, however, he takes less than thirty seconds, the timer simply resets without subtracting any periods. This is written as <maintime> + <number of byo-yomi time periods> of <byo-yomi time period>. Using up the last period means that the player has lost on time.
[edit] Compensation
These methodologies typically requiree the use a special clock. There are two main forms which provide compensation for both time pressure and time lost in physically making a move.
- Bronstein delay - when it becomes a player's turn to move, the clock waits for the delay period before starting to subtract from the player's remaining time. For example, if the delay is five seconds, the clock waits for five seconds before counting down. The time is not accumulated. If the player moves within the delay period, no time is subtracted from his remaining time.
- Fischer delay - when it becomes a player's turn to move, the delay is added to the player's remaining time. For example, if the delay is five seconds and the player has ten minutes remaining on his clock, when his clock is activated, he now has ten minutes and five seconds remaining. Time can be accumulated, so if the player moves within the delay period, his remaining time actually increases.
[edit] Penalty Formats
Such methods exact a points penalty, or fine, on the player who breaches their time limit. One example occurs in Go, where the Ing Rules enforce fines on breaches of main time and overtime periods [4]. In tournament Scrabble the time control is standardized to 25 minutes per side with a 10-point penalty for each minute that is used in excess[citation needed]. The number of extra minutes is rounded up, so that overstepping time control by 61 seconds carries a 20-point penalty.

[edit] Time Control in rally
The article as is only covers board-game tournament use of the phrase, but the phrase also refers to rally races where check points along each leg are 'Time Controls' where the driver's time card is checked and marked, and penalties are imposed for arriving too late or too early. --Barberio 19:31, 21 January 2007 (UTC)
- Good point, some sort of disambiguation would be needed if Rallying couldn't be fitted into the article then.--ZincBelief 15:30, 5 March 2007 (UTC)
[edit] RFC: How the remaining time is being written
[edit] Standard Byoyomi
This is written as <maintime> + <number of byo-yomi time periods> of <byo-yomi time period>.
- I have seen it differently on common use, including the KGS and tournament papers.
| Description | Notation |
|---|---|
| On tournament games I have seen it like this: | 30:00+5x0:30 |
| That's, what a typical game clock says before time has run out: | 29:57 |
| Let's say, we have only 4 periods left: | 0:27 (4) |
| Now, when only only one period of Byo Yomi is left: | 0:13 SD |

[edit] How is Fischer time a subset of byoyomi?
Since the additional time you get under Fischer time carries over I can't see how byoyomi can simulate Fischer. Taemyr 13:32, 15 August 2007 (UTC)
The article doesn't list Fischer time as a subset of Byoyomi as far as I can see? It's listed in Overtime under compensation (delay) methods - a seperate section from byoyomi. Have I missed something? --ZincBelief 13:44, 15 August 2007 (UTC)
- Yes, you have missed something. From Time_control#Overtime_formats; Byoyomi and Canadian Byoyomi time controls are actually supersets of Absolute and Fischer time controls. Taemyr 13:48, 15 August 2007 (UTC)
- Yuck, who wrote that in... I don't follow that sentence at all. Canadian Byoyomi is a subset of Japanese Byoyomi. Comparisons with others are misleading. I will edit this. --ZincBelief 15:09, 15 August 2007 (UTC)
[edit] Time Trouble
Does anyone else feel this is slightly out of place. Detailing the FIDE laws of chess with regards to Time Trouble doesn't exactly fit for me into the Subject of Time Controls. Time Control is surely refering to how time is allocated for each player. It should not refer to how one will behave during certain (time) regimes.--ZincBelief (talk) 12:42, 2 May 2008 (UTC)
- I was the one who added the section here, and I won't object to the material being moved to another article, or split out to a separate article if that is appropriate. However, I do object to removing the material altogether, because time trouble is a very major consequence of time controls, a factor which features in lots of games among strong players, and a factor which is well-covered in some books (e.g. Chess for Tigers). The fact that rules were made to govern that testifies to that time trouble is a significant part of the game. The Oxford Companion to Chess, the closest thing we have to a specialized chess encyclopedia, has a separate entry on "time trouble" (so the topic is "encyclopedic"). At the time, I didn't feel that I could gather sufficient material for a stand-alone article, and adding it to this article seemed like the best fit. Sjakkalle (Check!) 13:22, 2 May 2008 (UTC)
- It is certainly a topic you can cover. I would imagine you can fit it into some chess rules page somewhere. I will have a look around to find a more suitable resting place. —Preceding unsigned comment added by ZincBelief (talk • How about http://en.wikipedia.org/wiki/Rules_of_chess --ZincBelief (talk) 13:54, 2 May 2008 (UTC)
