In (a) Responder take a risk and bid 3NT after the good news,
but if Opener bid 3
then Responder correct
for 3 sign-off;In (b) e (c) Responder have a complete sign-off hand, and should pass,
in (c) Responder should pass if Opener deny support in diam bidding 3
,
that is one of the justification to use the negative bidding Clubs,
the other is transfer the hand to strong hand in a hard game contract.
