Well, you are the only one to respond to this part of the thread, so I guess I'll wrap it up here.
I don't really like an initial 3n or a 4s bid here as you put a lot of pressure on partner to bid further. I've always found it profitable to "bid where you live". In other words, show the values you have so partner can make an informed decision.
Partner's hand is:
I was hoping for more discussion on the 4d bid, I was wondering how many people have discussed this kind of situation. I play with my regular partners that after a strong jump shift, such as 3d, weakest bids are rebidding your own suit, rebidding partner's first suit as a temporizing move, rebidding 3n showing values outside of partner's suits, or raising a minor straight to game. So we prefer having a 4d bid mean more than 5d, although some partners disagree on what a 4d bid should ask. Some like it as minorwood, but I hate that by a responders hand. So 4d here was meant as forward going and cooperative for more. 4s puts a lot of pressure on partner to evaluate the 3 fast club losers and continue on. For that reason, I like 4h, bid where you live. Partner won't think you all of a sudden found a 4th heart and should treat it as a cuebid. Over that, partner can bid 5h or 6d (5d would be cowardly) and I would infer that partner has at least a doubleton spade as with shortness, they would continue to cuebid. After that, 6s is not difficult.
I found this hand interesting in that it was play 17 times and only one pair bid the slam and only one other pair bid to 5s looking for more. 15 other pairs stayed in 4s, which indicated to me that this was a difficult hand for standard American or 2/1 systems.
It is very difficult to be objective on these hands, once we know the actual layout. That layout looks very bad for my 3N choice
Having said that, I do think that a pass of 3N by responder doesn't do justice to the hand, which surely has some slam potential and, when not, should afford safety at 4N (and in any movement over 3N, a bid by either partner of 4N must be an offer to play there).
So what should South do?
At the risk of allowing my knowledge to influence me, I think S is worth a 4D call: natural with mild slam ambitions.
Over that, North has an enormous hand: I cannot see not driving to slam opposite this. I would expect a good 5 card suit or a decent 6 card suit, in order for south to move, and off course North can count tricks opposite as little as x xxx KQxxxx xxx, when surely South has more than that.
The key is whether South should show the diamonds. I think he should since slam is probably not great opposite many 18-19 counts unless partner 'likes' diamonds. For one thing, the partnership may need to be able to ruff a spade in order to generate an important trick.
It is perhaps ironic that the risky 3N, imo, offers a better chance for slam than the fake jumpshift that catches such remarkable support. The problem is that after 1S 1N 3D 4D, North has a routine 4S, and south may feel he has already shown some mild interest in a high level diamond contract, so to move again shows 'more'. Whereas, on my auction, South has shown nothing at all as of 3N, so can afford to show his hand via 4D and now North really can't help but bid slam. However a lot of players, unaware of how to evaluate hands, would simply pass 3N, not understanding the power of that KQJxx holding, and/or maybe lacking confidence that the auction can always end at 4N.
Say opener had AKQJxx Axx x Axx....over 4D, opener can offer 4S. With, say, AKJxx Axx xx AQx, opener offers 4N.
