Fred, I never meant that reaching 6NT was one of the primary reasons I like 2♣, though it works out well on this hand. I just thought that it was more likely to gain information at a lower level so that I could hear more about partner's hand. Justin, I would agree with you that if I were sure I could tell partner all these things about my hand, I would. However, I'm not sure why the auction should time out this way. Over a 4♠ signoff after partner shows slam interest or a 4♥ cuebid, we can continue to describe our hand at the 5-level, but I think you will agree that partner will not get all the information we wanted him to get. In my opinion it is better to just listen to what partner has to say and try to make an informed guess with this kind of hand. It was actually quite difficult for me to construct a wide variety of hands where my fourth trump is very important to partner, given that I am actually 4333. I found that in fact it is more likely that I want to know what partner's hand looks like, since the play will probably involve ruffing twice in partner's hand when he has a 4-card side suit. I would actually like to see some hands where responding to 2NT will work out better than 2♣ in a style where we usually open 1NT with 15-17 balanced and 5♠. I am not denying that they exist, I would just like to more carefully consider the problems with bidding 2♣ here.
