1.  doesn't matter.  I don't mind multiple solutions but see (4) below.
2.  doesn't matter as above.
3.  some of them.  I don't want all 800+ as it takes too long to run.
4.  no.  this is a key point.  I used to (in Cray Blitz) have a suite
    format that had this:  solution Bxh7+(+2)  CB would not count Bxh7
    as correct unless the eval was also +2 in material or more, which
    prevented lots of right moves for wrong reasons solutions..  I don't
    want "accidental" solutions as it makes comparing results with
others
    (or old versions) very difficult.
