	This is a perfect case to illustrate what I mentioned in my follow
up to the original article. In this example it is clear that Black
manages to avoid cranking his points up by being in a totally defensive
position where his best choice happens to be his only choice.
It is interesting to note that no matter what kind of scoring
scheme is used or how wide the score gap between White and Black,
White will eventually 'catch up' with Black by using the second best
(not necessary the worst) move strategy to force Black to make the
best (which may often be the only legal) move in every response.
	Well, guess the truly great chess players are not necessary
the ones who make perfect plays, but the ones who can AFFORD
deviations.
