For the correct working of the move counter driven Bonus Tournament op-
tion, the players are obliged to correctly stop the clock after each
fi
nished
move, so that the clock keeps track of the played number of moves
Always ensure that the lever is in the correct position and the player color
icons are correct before a game begins.
6. Delay (“Bronstein”) (Options 22 to 25)
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
fi
rst move. Before this main thinking time starts counting down
the player has a
fi
xed 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 Bonus
methods. The delay time is initially added to the Basic time.
The clock always shows the total available time, that is the main time plus
the delay time per move (or, on a running clock, the remainder of the main
time plus the remainder of the delay time, if any)
7. Time + professional byo-yomi (Options 26, 27 and 28)
From its very nature the game of Go lends itself naturally to allowing play-
ers extra time to complete a game. Traditionally, the byo-yomi method is
used for this. Byo-yomi gives the player who has used up his thinking time
a
fi
xed amount of time for each subsequent move.
In normal games of Go the principal thinking time allowed is 1 1/2 to 2
hours, usually combined with a byo-yomi of 20 to 30 seconds. After the
principal thinking time has been used the clock jumps to byo-yomi time.
Each time a player completes a move the clock jumps back. If the player has
not completed the move before the clock reaches 0 a
fl
ag appears in the
display. For top matches the principal thinking time can be 9 hours which is
followed by 5 byo-yomi periods of 1 minute each. At the end of the 9-hour
period the clock jumps to 5 minutes. If the player completes a move be-
fore a time of 4 minutes is reached the clock jumps back to 5 minutes. If he
completes a move after the 4-minute period has been exceeded, the clock
reverts to 4 minutes. The clock thus reverts each time to the beginning of
the current byo-yomi period.
Note that the icon “byo-yomi” is shown in the display as soon as a player en-
ters the byo-yomi phase. The
fl
ag sign is not shown yet, the
fl
ag sign is shown
when a player reached zero, during byo-yomi. The game can go on, the
fl
ag
is cleared when the players next turn starts.
8. Time + Canadian byo-yomi (“Overtime”) (options 29, 30)
Canadian byo-yomi o
ff
ers a simpli
fi
ed version of professional byo-yomi. It
gives a player the extra time to complete a number (5 to 25) of moves in-
stead of extra time per move. After passing the
fi
rst period (TIME), the byo-
yomi time is given, and the byo-yomi icon is shown in the display. When the
agreed number of moves is made, the players clock can be reloaded with
the byo-yomi time by pressing the “-“ button for 1 second.
