Another Interesting Bidding Challange
Jimmy:
Picked up this hand yesterday. Ended up in 6 !S, making 7 when the !H's were split 2-2.
How does OCP approach this beauty?

These hands are a delight. Nice going to get to slam.
Maybe others might approach this differently but my bidding would be as follows:
1 !S-1NT
I plan on a Gamma in !S. IMO this hand is too strong for Exclusion Beta [10-12 HCP more appropriate].
2 !H-3 !C [Gamma in !S]
Wow, Two fits with at least 9-cards in each fit [Responder also has the option of bidding 3 !D (gamma in !H)]
4 !C [Hxxxxx]-4 !D [Relay Beta]
4NT [4 controls]-?
At this point, Asker knows Teller has either AA or AKK for controls. If Asker ponders it, they can rule-out AKK because in that case the two Kings would have to be in the Minor suits and Teller has already shown 10-cards in the Majors [6 in !S and at least 4 in !H] leaving only 3-cards at most for the Minors. If Teller had both Minor suit Kings one would have to be a singleton - a big no-no in Beta responding. So you can narrow Teller's controls to AA but where do they reside? IMO Asker must ask in clubs simply because they are possibly facing two quick losers there. So, continuing the sequence:
4NT [4 controls]-5 !C
6 !C [first-round control]- 6 !S
Unfortunately we are out of space and really can't assess whether Teller's first round control in !C is either a Void or Axx [both are possibilities]. Some gambling folks might think it can't be Axx because we would be double void in Diamonds! and surely the opponents would have pipped up if that were the case. On that premise, some OCP practitioners might have pushed to 7 !S but do not include me in there.

Me neither! Nine cards and you need to find the Queen to make is fair game for a small slam, but it's not good enough odds for a grand slam. Bidding 7 of a major on Jimmy's hand will be a net loser in the long run.
Jimmy:
Hi Guys,
Thanks for the responses. John, have a question for you.
In your response you used the forcing one NT bid with opener bidding 2H and responder now bidding 3C gamma.
How does the bidding proceed if opener bids 3S showing max with 6 spades ( in effect, hiding the heart fit)?
1 !S - 1NT
3 !S

I'll let John wrestle with the sequences, but I have to say that if the 3 !S rebid results in your missing the slam, I would put the blame 100% on opener, and I don't need to see the rest of the sequence to say that! ::)
IMO, at least, the only excuse for suppressing the !H suit is if it's abysmally weak, and by that I mean something like 6xxx, not A10xx. If your spades are long enough in a maximum hand that you feel you have to hide a decent !H suit to bid 3 !S, then you should probably have promoted the hand to 1 !C in the first place.
Just bid 2 !H. If responder passes this then it's probable that 1NT was a desperation measure on a weak 0=4=4=5 or something close to it, and 2 !H is probably a much better contract than 3 !S. If responder intends a rebid, then you'll be much better placed when you have some idea of what responder has, and if responder wants to take control and go into the strong sequences, then you've made a much better start on describing your hand.
