DGT NA

The upcoming Southern Open states:  5SS, 40/110, SD/30, d10.  

My DGT NA offers setting 10, Time + Bonus (Fischer) and 23, Delay up to 3 periods.  Which (if either) of these should I use for the tournament? 

Also, can someone explain the difference between Fischer and Delay?

Delay:
After the clock is hit, the opponent's clock does not immediately start.  It's effectively paused for the length of the "delay."  If you move before the delay is over, no time is lost, but no time is added either.  With delay you never gain time on the clock.

Fischer:
After the clock is hit, a number of seconds are added on to your clock.  If the time spent on a move is less than the amount of the add on then effectively you gain time on the clock.

Both:
As long as the players move faster than the delay/addon it's impossible to lose on time.

Thanks Wafflemaster.  From your explanation I guess I would use delay and not Fischer.

Yes, the time for the Southern Open is a delay time not a Fischer time which adds time to every move.  I think you would use the manual setting for the delay time with two periods.  But do not worry about it at the tournament you can always find someone that knows how to set that clock.  It is very popular at tournaments.

BTW, in the time description for a tournament the Fischer Time would be described as someting like 40/110 inc. 30   SD 1hour inc.30  The inc is short for increase which adds time.  Thus Fischer!!  The d means delay you will not have both.
