Introduction: Timing Methods

Time is an exciting aspect of many sports. This is certainly true in

games such as chess, go, draughts, shogi and Scrabble®. A players'

skill is determined not only by decisions, but by how quickly those

decisions are made. The more a sport is seen as a contest, the more

important it becomes to reduce the time a player has to perform an

action. This should be realized in a way that is closest in line with the

typical features of the contest and the sport that is practiced.

The DGT XL offers 11 different standard methods for timing two-player

games. The thinking times that are most commonly used are pre-

programmed in the DGT Clock as options 1 to 22, but it is also possible

to combine different methods by manually setting your own personal

preferences (use option 00).

Whilst several methods are well known, others may be less familiar to

you. Several of these methods have been in use for a long time; others

are the result of the possibilities now offered by modern electronics.

Every method has its own charm and has an influence on the manner

in which a sport is experienced.

The traditional "quickie" of 5 minutes per person is different from 3

minutes using 'Bronstein' or 'Fischer' in which every move attracts an

extra 3 seconds of thinking time, although the total thinking time for a

game is hardly any different.

We recommend players to experiment with the various methods which

the DGT XL offers. It can add an extra dimension to your favorite

sport.

1. TIME (Options 1 to 5)

This is the simplest way to allocate time. Each player is given one period

in which they must make all moves.

2. 1 PERIOD + Guillotine (Options 6 and 7)

The first period is used to play a predetermined number of moves. The

second period, the Guillotine, is used to finish the game. 1 Period +

Guillotine can be used as an alternative to the traditional ''Rapid and

Blitz'' with a quiet start.

3. 2 PERIODS + Guillotine (Option 8)

For a less frantic game, it is possible to play a game with two periods

before the Guillotine.

4. 3 PERIODS + Guillotine (Option 9)

A quiet end to a game also has its advantages. The simple traditional

clock gives the players repeated one-hour periods in which to

complete a predetermined number of moves.

For more than 50 years, it was standard in chess to play a serious

game in two periods separated by a break. This had two

disadvantages:

Games could not always be decided after two periods.

From 1990 onwards, the increasing strength of chess computers and

endgame databases added what some considered an unfair advantage

in the ability to analyze adjourned games.

Various proposals were made for ways to finish games in one session,

without having to resort to the Guillotine method, as this method may

influence the final result of the game in a way that can be

unsatisfactory to the players.

The 'Bronstein' delay' and 'Fischer' methods provided a solution by

giving players a predetermined amount of extra thinking time after

making each move.

After the introduction of the Digital Game Timer in 1994 the application

of the above-mentioned methods has been a major topic in discussions

in the chess world. The results of these discussions have been translated

successfully into the new DGT XL.

5. 'Fischer'- Blitz, Rapid and Slow (Options 10, 11 and 12)

This method applies from the first move, allowing a player to gain

extra time apart from the standard period, as every completed move

attracts extra time. By completing moves in a time that is shorter than

the extra time per move, a player can build up the thinking time

available for subsequent moves.

Note: The DGT XL remembers, through the operation of the lever

at the start of a game, which player is playing white. The icons

and

in the display (Fig. 2 F) clearly show which player is to

move. This has consequences for the moment when a player

exceeds the available thinking time for the first time. If black is

the first to exceed the allotted time for the first period then

white receives a double bonus. The correct operation of the lever

is also important in the 'Fischer' and 'Fischer Tournament'

options.

6. 'Fischer'- Tournament (Option 13)

The 'Fischer'- Tournament method is the most complex in the way

thinking time is regulated. In addition to the extra time available per

move, the player is also allotted an extra amount of principal thinking

time after a predetermined number of moves has been completed.

For this option a move counter is available. This counts the

number of completed moves (that is: the sum total of the moves

played by both white and black). The allocation of new principal

thinking time occurs only at the appropriate moment if the DGT

XL is carefully operated.

7. 'Bronstein'- Blitz, Rapid and Slow (Options 14, 15 and 16)

The oldest proposal from the chess world for a solution to the problem

of limited thinking time came from IGM David Bronstein.

His method applies from the first move. The principal thinking time is

reduced by delay. Before the principal thinking time is reduced the

player has a fixed amount of time to complete a move. It is not

possible to increase the thinking time by playing more quickly as it is

in the 'FIDE' and 'Fischer' methods.

8. 2 PERIODS + 'Fischer' (Options 17 and 18)

This method also applies from the first move. Starting the game in a

traditional way, the player has to complete a predetermined number

of moves within a fixed period of time. By playing the last period using

'Fischer', situations where time trouble influences the result of the

game too much can be avoided.

Always ensure that the lever is in the correct position before a

game begins.
