In the Tuesday Pro-Am, this hand popped up at our table, and I am still befuddled as to how to get to the ultimate contract.  In third seat, red on red, you hold: ♠-xxx, ♥-AJxx, ♦-AKxxxx, ♣-void.  Partner opens 2NT, and after your regain your composure, you bid 3♣.  Partner bids 3♥ and you wonder how high to bid.

If I am playing with one of my experienced partners, I would start cue-bidding with the intention of getting to 7 something. But with a "newbie" I just bid 6♥.  Partner makes 7 Hearts with the following hand: ♠-A, ♥-KQxx, ♦-QJxx, ♣-AKJx.  As you can see, 7NT is cold - but how in the world do you get there?  Any suggestions would be greatly appreciated.

Sincerely, Jim Somma
