The following incident occured at a recent meeting of our local go-club.

Two players were discussing a seki situation in which white had
extended a single stone, after black captured the two of them and white
captured back to return to the previous position. They called me over to ask
what the ko-rule says about this. I explained that the position was not to
be repeated upon which one player asked whether that includes the turn,
because the only effect of the last three moves was that it was now black's
turn. I said I remembered that the turn was indeed included, but was
subsequently asked whether that means the black player was not allowed to
pass. This struck me as very odd; surely passing should *always* be allowed.
So that made be decide I must have been wrong in thinking that the turn
is part of the position.

So my question is:
is there any rule-system in which the no-repetition rule
includes the turn in the position? do they also state that a player
may pass at any turn?
