Had to change the title. :)  By the first hypothesis do you mean you will
simply rediscover what is accepted opening theory?  Or that you will
determine which lines are soundest?

How exactly does this sort of solving work anyway?  I mean, I can see it
in general terms, but I'm not sure of the details.  Suppose you're at a
certain position, and you see that you have five moves from that point
in your database.  They have centipawn values of +50, -75, +123, +64, and
+10 for the side on move.  What is the value of your current position?
An average?  If you assume that your opponent makes the best move then I
suppose the value must be the least, or -75 in this case.  If you apply
this to each point in the database, you should develop long variations
based on this "least" (best move for the other guy) value at each point.
Is that about right?  And does it matter where you start, or can you
locate the "ends" of each variation?  Then you have to consider how to
add new data into a "solved" database.  Or make a correction.  Suppose
you do a longer analysis and a new point has the least value. I suppose each
point can have a "raw" original data value and a "solved" value, both of which
could be updated as needed.  Interesting
stuff anyway.
