Fischer'- Blitz, Rapid And Slow (Options 10, 11 And 12); Fischer'- Tournament (Option 13); Bronstein'- Blitz, Rapid And Slow (Options 14, 15 And 16); Periods + 'Fischer' (Options 17 And 18) - DGT XL Gebrauchsanweisung

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
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.

9. 'GO' using the Canadian Byo-yomi method (Options 19 and 20)

This method is derived from the original Japanese Byo-yomi method of the game 'GO'.
