It is fairly clear to me.  You ask the players for the status of each 
group (alive, or dead.  Alive in seki is a special case of alive). Where 
they agree, you accept what they say.  Where they differ, you have to 
find out "whether it can be captured", with its would-be capturer moving 
first.

Of course, if the players do the finding out themselves, there is a 
danger that you end up with two adjacent dead groups.  If this happens, 
I am not sure what to do next.

Agreed.
