Rainer's example may be a bit contrived, but there are so many hands that partner won't even begin to move over 2♥ with, where game is excellent, if not cold. Rainer's example might even pass 3♥! Facing anything but terrible wastage in both minors, game rates to be a fairly good contract, and 3♥ should be fine when partner passes. I still don't see the point of 2♥ though, we're not getting too high that often.
