Yes, if it is trut for both players that if they play first, they get a
result that is worse than letting the situation be and agreeing it is a
seki. Not very useful, I know, but then only short definition I could think
of.

Which tournaments? Things are different in Japan and in China. Some sponsors
have clear preferences towards some rule sets, as do some clubs. There are
heated discussions on these matters, which I have tried to stay away from.
I am sure someone else on this list can point you to various "official"
rules...

Again, it depends. By old Japanese rules it voided the game, and brought bad
luck to both players.

I do not remember, it was somethign pathological, with two-stone strings
getting captured back and forth, making a total of 3 eyes for 2 groups.
I never studied it, just remember that there was a pathological example.
Maybe someone else can shed some light to this?
