My partner opened the bidding with 1♦, and my thoughts turn immediately, to some type of slam, even NT may be right if partner is 3, 3, 6, 1 or 3, 3, 5, 2.
I bid 1 ♥, planning for a reverse to ♠ as a rebid and a rebid of ♣, if I keep hearing diamonds. The bidding could perhaps go,
1♦ -> 1♥ -> 2♦ -> 2♠ -> 3♦ -> 4♣,
Another possibility is to start with 2♣ as in,
1♦ -> 2♣ -> 2♦ -> 2♥ - > 3♦ - > 3♠
I have to assume it is reasonable that I would have at least 1 quick entry to partners hand unless he has AKQJ10 ♦ and J♥.
Anyways, after my 1♥ bid he responds 2♥ indicating a minimum opening with 4 hearts. Having found a fit but in my weakest suit, I have a different problem of my rebid.
Asking for Aces in RKC is wrong in my books because if he gives 1 Ace I have no idea if it is the A♦ or K♥. I chose 5 ♥ as a rebid to ask about the quality of the trump suit, this seemed like a reasonable risk as even with 6,5,4,2 ♥ in partners hand is still only 2 losers on a 3-2 ♥ break.
Would anybody bid 5NT as a grand slam force?
I'll follow up on the bidding and play, after a while, any and all comments appreciated.
