I think East should discourage. In this sort of situation, encouraging should say that it's OK for West to continue with a low one. That is, you cater for AK9x opposite Qxx, but not for AKxx opposite xxxxx.
On the occasions when the suit is cashing from the top, the leader may be able to work out that this is his best chance anyway, or you may get another chance later, after East has had a chance to make a Smith or suit-preference signal.
I can't, however, see West switching to a diamond, regardless of what East signals.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
