Fischer Timing
Keywords: Rules, Tournament
Definition
Fischer Timing is the time system where
- one gets an amount of time (say, 5 minutes),
- time used for each move is deducted,
- and an extra amount of time (say, 15 seconds) is added after each move.
Remarks
Players' remaining time
- grows as long as they use less than the post-move increment
- and declines when they use more -- on average.
- is always at least the incremental amount for each move
The Players' overall time limit is linearly dependent on the number of moves (e.g. you can tell that a 300 move game with 30 min + 30 sec/move will last for a maximum of 210 min).
There is no spilling of unused time.
There are no periods. All you have to watch is the time.
Example
5 minutes plus 30 seconds bonus.
# Time Used ------------------ 1 5:00 1:00 2 4:30 1:20 3 3:40 2:40 4 1:30 0:10 5 1:50 0:20 6 2:00 0:30 7 2:00 2:00 8 0:00 lost
If it were only one second less in step 7, life would continue with 0:31 on the clock.
