Big hand opposite reverse

[AL78]

Acol, weak NT:

 

♠82

♥Q

♦AKQ964

♣KQ94

 

With opponents silent, partner opens 1♥, I respond 2♦, partner bid 2♠. How do you plan to continue?

I start with 3C see if partner can support diamonds or maybe even raise clubs 5404 clubs would likely be our spot.

[AL78]

I bid 3♣ for the same reasons and I'm thinking of small or grand slam in as yet an uncertain denomination so would like some more information from partner. Partner responds 3♥ which can be interpreted as nothing more to show (i.e. not guarenteeing extra heart length), now what?

The hands are not fitting well, but that ♥Q is a key card. I am trying to work out what shape partner is, and what cards he has for the reverse. 4♦ just looks right and forcing. No need to rush as you know you are in the slam zone. The problem is if partner now bids 4♥. After that I know we could miss a grand, but I would just bid 5NT pick a slam and settle for the small slam. There are many, many hands, where you will have 13 tricks off the top, but finding out about the quality of the ♥ suit is not possible to do imo. Partner could be reversing with ♠AKQx ♥AKxxxx ♦x ♣xx where even a small slam may not make. But on the combined point count alone I would want to be in a small slam as there are squeeze possibilities.
