Yes, but I'm not an expert so take it with a grain of salt. :-)  The knowledge
you mention seems correct but would be almost useless without a deep search so
it seems to me the search depth and knowledge are intertwined and as everything
else in life, must be a comprimise.  Unless you have deep blue hardware and can
afford both.
