Subject: not promoting rook or bishop? (about Sam Sloan HP)

  I've been reading Sam Sloan page about
shogi and I've noticed in one of his "(work
this out)" remarks that there exists positions
where it is better to choose not to promote
the rook or the bishop.

  Can anyone give me a sample position in
which one should better not promote Rook or
Bishop. I just can't believe it. (Well, if it
wasn't Sam I'd actually discarded it yet).

  I can't understand how can an unpromoted
rook or bishop do just anything their
promoted versions can't (being their
movement pattern a superset of the original
ones).

  If this is true, I guess that it has something
to do with some strange rule application I
don't know.

  I'll be right here waiting your comments.
See ya'll.
