Dia. 6-16-1 is an example in which Black can capture one of the two
strings of white stones. Let's play this out by territory rules I. Black
has made the last move. After two passes to establish the preliminary
end of the game, White plays 1 in Dia. 6-16-2. Black plays 2, and the
exchange through White 9 follows, after which Black has to give White
one more stone by the rule of equal numbers of moves. Dia. 6-16-3 shows
the final result. Black has thirteen points of territory minus seven
prisoners: total six. White has seventeen points of territory minus
eight prisoners: total eight. White wins by two points.
White also wins by two points under area rules III. How this position
should be resolved under traditional territory rules is a problem, but
if it is played out, again White wins by two points.
