It is possible, and I would think extremely likely, that there is more
to this PV than what you see.  Eight moves is not a lot to return from a
10-ply search, so it appears to be truncated, and given their preference
for expensive extensions, possibly extremely truncated.

On the other hand, it would surprise me a little if a micro couldn't see
as much after giving it 8 plies of "solution" for free.

I let mine search for an hour or so, and still +1.27 (from white's point
of view).

I thought that this was going to be the primary evidence for cheating.
If this evidence doesn't work, what other evidence is there?

I mean, eventually someone is going to say that Karpov was making all of
the moves, and the whole match is something out of "Capricorn One", and
there will be no way at all to "disprove" that, will there?
