Over 3♣, I agree with Siegmund that a new suit shows clubs. Without hearts or clubs you would just bid 3NT. But I prefer 3♠ to 3♦ on your hand because you want to play 3NT when partner has short spades, e.g. x AQxxx KJx Axxx.
Also, I think you have to allow for the possibilty that partner just has a slam try in hearts, e.g. xx AKJxxx Qx Axx. In a regular partnership you might agree that a transfer then 4♥ is a slam try (because you didn't use Texas), but in a pickup partnership I would just pass 4♥ because partner might not have clubs when he retreats immediately to 4♥.
But your partner's 4NT and 6♥ were the only two calls I really dislike.
I definitely see the point of 3
♠ over 3
♣. After 3
♣ I first gave passing thought to 3NT but after a diamond lead I would need, as far as I could see, 8 more immediate tricks. At that time I was not yet thinking about slam. Bidding 3
♠ would often get us to 3NT when it is right.
Myself, holding xx AKJxxx Qx Axx opposite 1NT, I would transfer to hearts and raise to four. If partner realizes that this is stronger than texas that would be nice but I would not risk confusion by bidding 3
♣. The 6-4 choice of games option I need to think about. It seems to me that if he wants to be in 4
♥ when I have two hearts and four clubs he should not screw around with the clubs. A 6-4 slam try appeals more to me but then still clubs may be (and was) the best strain.
I really do appreciate all these thoughts even though I am not entirely convinced. Mostly I have trouble seeing why partner would bid 3
♣ if he wants to play in hearts when I have two small hearts and KQxx of clubs. Had he transferred to hearts and bid 4
♦ I would assume hearts are trump and he has a stiff diamond. I would bid 4
♥.
Anyway, thank you all for your thoughts.
