kaluza: Also, there are tricky positions that are difficult to figure out. These would require some discussion between the players and possibly multiple attempts to mark the stones.

There is a message system build into BrainKing, so players can discuss the status of the groups. If it is dificult to decide the best way would be to play it out. As for beginners who need multiple attempts to mark dead stones: I haven't thought of that an I guess that isn't such a big problem. If all dead stones are removed in the (after-)game it just vanishes, since there are no dead stones to mark.

And I think that any set of rules that leads to an end is better than the current ruleset. If you pull a stubborn opponent who just doesn't want to loose, even with no more stones on the board you can do nothing - except calling Fencer to end that game or resign.
