Dansc: Canadian overtime is often used in face-to-face games when the game clock is analogue and cannot count japanese byo-yomi. The player in overtime takes the necessary stones out of the bowl and the clock is set to the period limit. Then you have to play the stones you took before the time is up, after which you start over again.
uxs: What happens when you have played the mandatory amount of stones, and you still have some time left? Does the new period start right away? Do you have some free moves while the remaining time counts away? Does the remaining time get added to the next period?
Fwiffo: The new period and set of stones starts right away. The clock is reset, so any time remaining from the completed period is not available.
uxs: That's stupid. I am now never going to move faster than I have to, just because it's stupid. Thanks for the answer though.
Andrew Grant: It certainly is stupid, but that's how it's done on the servers and in most tournaments. In the Milton Keynes tournament in the UK, which I organise, you get to play extra stones while your time lasts and the next overtime period only starts when your time runs out. You will find this method described on the BGA website (along with a spurious rationale for using the "immediate loss of time" system instead).
Robert Pauli: Sometimes being fast is better, uxs.
There was an obvious move to do, but it would have started a new period. Still some time to spend, the player decided to work out the best yose sequence. Finally he played the first move in this sequence - skipping the obvious move and trashing it all.
Confused: With Canadian overtime, uxs, you can decide a little on what moves to spend your time. With Japanese byo-yomi you just have a limited amount of time per move. If after playing nearly all stones in Canadian overtime you have time left, you can use it count, read more etc. If the situation is so clear that you don't need the time, that's fine too. It makes the game quicker. All in all, the Canadian system strikes a quite good balance between a short game and still giving you enough time to spend on difficult situations.

blubb: Damn, if I compare this page to former versions, it appears completely garbled now by eccentric definitionism. I doubt a common beginner looking for the meaning of "Canadian Overtime" finds it helpful.
Bill: Why don't you pick a good version, copy it, and restore it? :-)
blubb: I hesistated to do so, because there seems to be someone trying to rule the domain of time system semantics. I've changed the page back to something more readable now, anyway. Hopefully, this doesn't start an editing war.
