At the end of the preceding section we noted that area rules I and II
are the simplest theoretically, and they are logically complete, but
they suffer from a reinforcement problem: when there are an even number
of neutral points a player can reinforce an uncertain position blindly
without losing anything, which makes the game less interesting. It was
also stated that this problem can be solved by deducting half a point
from Black's score and adding half a point to White's score when Black
makes the last competitive move.
If we add this rule of half a point for the last competitive move to
area rules II, we will have area rules III. These rules will be a rather
significant advance in area rules because they will make the game more
interesting in practice. If we can only give a complete definition of
the last competitive move, we can claim to have a set of rules that is
optimal in both theory and practice.
