I would have thought something like
1♦-1♥
1♠-2♣ (4SF GF)
2♦-3♥ (which should now be suit setting) ought to get you there
Yes, that's the sequence I would think gets things going.
miamijd brought up an important point about which bidding sequences are forcing and which are invitational. They are related to how you play 4th suit forcing(FSF). As pointed out, most people play FSF as a game force and a jump in the major is simply invitational.
Playing it that way, you have options over opener's 2
♦ rebid. If East bids 2
♥, it shows at least 5+
♥ and often 6 and a game force still applies. A jump to 4
♥ is a signoff often with long broken
♥. So, a jump to 3
♥ really sends a couple messages. It says "I have really good
♥ and want to play in
♥" and "I have a good hand with at least some mild slam interest".
The East hand fits the 3
♥ bid even though only having 13 HCP. It is a 4 loser hand because of the long solid
♥ and
♠ Kx. A
♣ control and 2 1/2 to 3 cover cards might make a
♥ slam a reasonable place to be.
Now let's swap chairs and look at it from West's perspective. How does this hand look with respect to slam opposite a good hand with strong
♥ and at least mild slam interest? Opposite something like just
♥ AKQxxx, or, even
♥ KQJxxx with extras, there's potential to take a lot of tricks. And, the West hand has controls in all the side suits. So West should cooperate at least in slam exploration at least through 4
♥.
So, I think West's next bid is a 3
♠ control bid.
If you understand that East with any possible interest in NT could rebid 2
♥ rather than 3
♥, then you might agree to use 3 NT over 3
♠ as a waiting bid/serious 3 NT. Then West could bid 4
♣ showing the
♣ control.
If you don't have that agreement, then I think East has to bid 4
♦ showing a
♦ control. West will know it's shortness but holding
♦ AK means East may be able to make a pitch a loser or two. By bidding 4
♦, East denies a
♣ control. So West has a choice of actions over 4
♦. An aggressive West might just bid 6
♥. A more conservative West might bid 4
♥. But over 4
♥, East can make one more push by bidding 4
♠ and West should continue to 6
♥.
