Fischer Bonus

This method was named after chess world champion Bobby Fischer: "Fischer Bonus" called FISCH in
this manual. In this method a certain amount of time is added after each move. If players use less
time per move than the set bonus time, then the time on the clock will be higher after the player has
finished the move than at the start of the move. The rules of the international Chess Federation
(FIDE) stipulate that with this method the clock can no longer be operated after one of the players
runs out of time in the last or only period. The clock "freezes" and a blinking flag will be shown. In this
method the FREEZE icon will be shown during the complete game in the upper part of the display.

US Delay

Another method to give the players extra time for each move is the delay method. The clock does not
start to count down immediately when the players turn starts, but will wait a few seconds before
starting count down. This method is mainly used in the United States of America and is therefore
called "US-DELAY" (US-DLY).

Delay

Another method to achieve the same effect as US-delay is to add the delay time to the main time
first. Then the clock starts to count down immediately. This method is called "Bronstein Delay" after
chess grandmaster David Bronstein. When a player uses less time for a move than the set delay time,
the time on the clock will be reset to the amount at the start of the move after the player finishes his
turn. When a player uses more time than the delay time for a certain move, then the delay time will
be added to the remaining time on the clock at the end of the move. In this method the total time
can never be higher than what it was at the start of the move. An advantage of this method over the
US-delay method is that the total time available is always displayed for each player. A disadvantage is
that the players cannot see whether or not they are still in their delay time. On the DGT 3000 this
method is called DELAY. The final result of this method is exactly the same as in the US-delay method.

Byo-yomi

This method is also called Japanese Byo-yomi, but in this document it will be referred to as BYO. This
method is mostly used in games such as Go and Shogi. Byo-yomi is almost always preceded by a
period TIME in which there is no required minimum number of moves.
Using this timing method it is possible that player A is in his byo-yomi period while player B may still
make several turns in the Time period.
In the byo-yomi period each player gets a certain amount of time per move. If a player ends his turn
within this time, the time on the clock will be reset to the value that it had at the start of the turn. If a
player does not end his turn within this time, the DGT 3000 will show a non-blinking flag on the side
of this player. The rules of the game determine if this player has lost the game, or is allowed to go on.
When the opponent ends his turn the byo-yomi time will be reloaded and the flag will disappear.
The Japanese term "byo-yomi" means literately "counting the seconds". In a byo-yomi period the
time is called out by an observer in intervals. The less time is left, the smaller these intervals become.
In most cases during the last 10 seconds the time will be called out every second.
A common setting in Go is 60 minutes TIME followed by 20 seconds byo-yomi. As mentioned previ-
ously the byo-yomi period can start at different turns for each player. For example the player with
white can have 10 minutes left in the TIME period, when the player with Black already played several
moves in the byo-yomi period.
In tournaments the byo-yomi time is often divided in several periods. For example 5 periods of 1
minute each. If a player uses less time for a certain move than the byo-yomi time, he stays in the
same period. When he needs more time for a move than the byo-yomi time, he will enter the next
byo-yomi period. When he runs out of time in the last period, the clock will show a non-blinking flag.
