DGT XL Digital Chess Clock
After the worldwide success of the DGT FIDE model digital clock, DGT presents
the DGT XL. The advantages include: Option to mix timing systems (e.g start with
a normal countdown period followed by a "Fischer" or "Bronstein Delay" period);
Increased display size: digits are 18mm in height; More display information
(timing system, current game period, white/black player indicator, ...); Buzzer
can be switched on or off; Easy operation with extra buttons; Extra upcount
timing method; Save and retrieve 5 user defined manual settings.
The DGT XL also connects
to the DGT electronic chessboard
and has special internet features like an option to display the
moves from ChessBase chess playing programs. You no longer have to look at the
computer screen to see what the computer played! You don’t have to take your
eyes off the board any more. You can now just check the display on the clock!
Currently Fritz 8 and Hiarcs 9 are the only programs supported, but more are
coming!
The DGT XL offers 11 different standard methods for timing two-player games. The
thinking times that are most commonly used are preprogrammed in the DGT Clock,
but it is also possible to combine different methods by manually setting your
own personal preferences.
While 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 experiment with the various methods which the DGT XL offers.
It can add an extra dimension to your favorite sport.
1. TIME: 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: 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: For a less frantic game, it is possible to play a
game with two periods before the Guillotine.
4. 3 PERIODS + Guillotine: 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.
5. ‘Fischer’- Blitz, Rapid and Slow: 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.
6. ‘Fischer’- Tournament: 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.
7. ‘Bronstein’- Blitz, Rapid and Slow: 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’: 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.
9. ‘GO’ using the Canadian Byo-yomi method: This method is derived from the
original Japanese Byo-yomi method of the game ‘GO’. When playing with
traditional clocks was the method that was most commonly used, an official who
would be in control of the time using a stopwatch would always accompany the
players. The player gets an extra 5 or 10 minutes of extra thinking time to
complete a predetermined number of moves, usually 10 or 15, after the standard
thinking time has been used up.
10. Scrabble® + Upcount: In Scrabble, games have to be finished, even if a
player exceeds the available thinking time. The more time a player uses after
exceeding the available thinking time, the bigger the number of points that will
be subtracted.
11. Hourglass: The thinking time for the player to move decreases, while
simultaneously the opponent’s thinking time increases. This method offers an
exciting alternative to the traditional ‘quickie’.
