[blml] Is this a psych?

[Robert Geller]

We've been having a bit of discussion about the following
hand in  Japan.   South is nv vs vul at imps, and holds
       J7  754  Q762  KQ95
North is dealer and opens 2D (multi) = a weak 2 in either major
or a strong balanced hand.

South bid 2NT, asking for North's hand type (strength/suit of
weak 2 or strong 2nt).   Obviously this is a tactical bid and one
would normally expect South to have more strength for his bid,
but the question is, should this be considered  a "psych of
an artificial conventional bid"?
