In order to also show the prisoner count correctly in SGF viewers, I'd
favor an approach that would first have a position setup with k-stone
black group in atari and j-stone white group in atari, then two moves
that'll capture the groups, then a position setup which will produce
the current position. Maybe you could introduce a property as an SGF
extension to declare that some SGF nodes are "virtual" and shall not
be visible to the user. But not sure if the result still won't be too
