|===|-------| time before
|--| time for one move
|======|----| time after
Remarks
Both players start with the same time on their clock.
Despite being simple, it invites unreasonable fast play to force the opponent to play as fast.
Example
10 minutes each.
# Time Used -------------------------- 1 10:00 10:00 1:30 2 8:30 11:30 1:40 3 10:10 9:50 2:00 4 8:10 11:50 0:20 5 8:30 11:30 5:00 6 3:30 16:30 0:30 7 4:00 16:00 4:00 8 0:00 20:00 lost
