Like the Beatles told us, "Imagine." They knew the secret to good bridge. Imagine... what your partner's and opponents' hands looks like, Imagine what card your Pard would need to hold for success. Then bid and play accordingly. We're going to continue our theme of responder rebids today in an auction that is as yet unlimited.
In each case, Pard will have opened a minor and rebid 1♠. We know he doesn't have enough to Jump Shift, so he is limited to around 17-ish pts... sort of limited, but not really.
