north should interpret 3♠ as a splinter and cue 4♣ (I don't believe about 3S not being a splinter after a natural 1H. Assuming they play transfers in other situations, ask how they play this sequence: 1C - (1D) - x (showing hearts) - 3S which is a very similar auction.
south should sign off in 4♠. what north should do now depends on their cuebidding style, but if you assume they cuebid 1st and 2nd round controls, he should sign-off in 5♥ knowing south has no diamond control. if they play kickback, 4S could even be RKCB.
i don't think this is sufficiently surprising even from a passed hand to wake up south to north's misbid. south should perforce interpret this as a particularly distributional hand. maybe something like 6520 which was wanting pass as dealer and make a 2-suited overcall. south having made an invitational raise and having signed off once can jump to 6S. This however would be sufficiently unexpected to wake north up to his error, so I think he should be allowed to convert to 6NT which should be sufficient shock for south to pass.
i would happily deny east-west a very small part of their redress though. i think the penalty double belongs under 'wild and gambling' so the extra -150 between 3NT= and 3NTX= they deserve to keep.
Yeah right, maybe in Wonderland, and even there, only if people turn their brains off during the bidding.
The first thing that should be clear is that West doubleshoted with a bizzare double - so his side cannot get any redress in any way.
And what about NS? Well, the whole sequence looks very suspicious. Righty has shown the range of 11+, lefty say 4+, I have 9 and partner with maximum 16 honors left bids 3♠. Ok, that's borderline but possible. But, assuming a spade splinter and opponents that didn't bid spades, well, that's almost impossible. Moreover, righty has shown heart length by doubling 1♦ which reduces drammatically the chanches od 3♠ being a legitimate splinter.
So, what else is possible, partner maybe found a creative way to bid a 5x6x hand? Hmmm... Who knows.
Anyway, if the range of opener's action is {spade splinter, 6-5 two suiter, something crazy} with appropriate weight factors, the 3NT bid is the ONLY LOGICAL ALTERNATIVE (to be honest, supposing the bidder has an IQ above 45). Why? It is very easy to see:
- in case a] it should be seen as a waiting bid hoping to hear about the club control (no much sense in playing a natural 3NT by a limited hand in a thin spot where you have a major superfit)
- in case b] bidding 3NT shouldn't look much worse than 4♦, after all, the diamonds may be running + AQ clubs + spade A = 9;
- in case c] 3NT offers most flexibility.
And I didn't even notice the possibility that the responder would/could remember he (maybe) plays transfers and take this into account. Be honest, how would you weigh the odds about the possibility responder would remember in this strange spot the agreement he had (or hear about it) at least once in his bridge career, without any UI? I would say something about 97% of occurences. Maybe even more.
Therefore, 6NTx has nothing to do neither with restoring equity nor with bridge nor with justice, but very easily it could be read as a little piece of sadistic director's behavior in a spot where the "damaged side" nailed themselves to -750 (or -550, dunno) anyway.
Sorry for disagreeing with you.
