But Winter is /not/ qualifying his opinion. He cannot prove that this was

putting much stock in its authenticity."

Which is plain different than saying it is wrong or untrue!

Phil, you are misrepresenting Winter's words here. Winter did not
say the quote was "wrong or untrue," or anything to that effect. Here
are his exact words, from the OP:

"No source is given, of course, because none is known (see, for
instance, the discussion in C.N. 4483), and that of itself should have
resulted in the quote being expunged. Are there not enough
authenticated chess observations to choose from?"

Clearly, Winter is saying that in his opinion, only
*_authenticated_* statements should be presented as quotes attributed
to a given person. Since no authentication exists for this one, he
believes it should not have been used, much less attributed to
Capablanca.
One may certainly feel that Winter here is being overly rigorous,
even pedantic, but one should not misrepresent him.
