correct... my "basic search" is an attempt to search active positions to the
point they are almost "quiet" or totally "quiet" by doing the various extensions
I do.  Then I tack on a capture-only search to clean up the last bit of
uncertainty when possible...  so that the static evaluator doesn't have to
understand hung pieces, forked pieces, whether the king is in check or not,
and so forth...
