Spilling

Definition

A time system is spilling if it could happen that had a player used less time for his first N moves he nevertheless would end up in absolutely the same time-system state. What this means is that surplus time is not carried over to the next time-system state. It is lost (spilt).

Follwing time systems are spilling:

• Bronstein Timing
• Round Down Timing and its special cases
  • Canadian Timing
  • Japanese Timing

Example

If a player in Canadian overtime has played his lot of stones for the current period, the next period with the next lot starts -- no matter how much time was left over.

Since this seems odd, two modifications exist:

• Steady Average Timing
  Resetting of time and stones happens when time runs out, not stones.
• Total Average Timing
  Remaining time after stones are done is not spilled, but added to the next period.
