Can you 7NT get to 2/1 on this hand with North being dealer?

Maybe, but I'm not so confident.

p-1
2 drury - 2 waiting
3 natural game try - 3 ostensibly retry
4 max no help - 4n keycard
5 one - 5 Q-ask
5N yes, no kings - 6 anything extra in clubs?
7 why yes! - 7N not an unreasonable MP guess.

I'd like to think that after making a club game try north should not go to 7 with just AQJx or AQxxx, but if you told me that at another time I perpetrated the same auction with only one of those holdings, I would believe you. I think more realistic is that south does not make a grand try.

No I can't.
(The only way it would work is if opener made a slam try showing 6 hearts, goads his partner into bidding RKC, then shows all keycards and K. But I would just start with a balanced slam try, i.e. 2N over drury 2.)

It's very easy when not playing Drury, but drury is part of 2/1 right?

Depends on what you are playing, obviously. Let's see how I would bid this with one partner...

P-1
2(Drury)-2NT(balanced slam try)
4(max, not primes)-4(RKCB)
5(one)...

Cannot find out from there.

Let's try a different method.

P-1
2(Drury)-2NT(balanced slam try)
4(picture jump)-4NT(RKCB)
5(one)-5(queen?)
6(yes, no club King)-grand

It seems that a picture option needs to be available in this sequence. Thus, I now think the older structure I used is inferior (partner's idea). Better after 2NT is to have 4-level picture bids, glumping shortness into perhaps 3 or 3 (extras, minimal) with relays to unwind, and 3/3/3NT for balanced unwinds. Something like that.

For those that play fit jumps by a passed hand, how far off is the North hand from such? (I presume that balanced hand is not a plus factor ). South would certainly perk up upon hearing a 3 fit jump response!

Honest answer: No, I can't.

But I will speculate, based on how the auction would begin with me and my clone.

Pass 1
2 2NT
3


2 was Drury, 2NT was slam going, 3 unfortunately just shows the ace. But now suppose that S gets excited about developments and decides to get inventive. It could go:

Pass 1
2 2NT
3 4
4 4NT
5 5
?

Here 4 is inventive, 4 is natural, 4NT is 1430 5 is one key, 5 is a Q ask and, since we are now committed to 6, and interest in a grand.

Now N gives this some thought. Apparently S has the king of clubs. Why else would he bid 4 before embarking on the invitation to a grand? All the keys are accounted for, he is looking at the Q of hearts, partner has expressed interest, he has tricks in clubs, so...?

Maybe it works. Maybe not. It's hard to count to 13 w/o knowing of the sixth heart, but partner is encouraging a grand and those clubs look pretty useful.


Probably we end up in six, posting about how to bid seven.

I might reach 6 a great deal of the time, but 7 seems hard.

Here is a concept... use 2 to show clubs and 2 as drury (assuming you play weak two diamonds). The reason being you are much less likely to want to bid 2 naturally as a passed hand, but you could easily have a hand that would have opened a weak two clubs -- if that was in your system (it will not be).

I have a chance to get to 7H, assuming I think south's hand is an ACOL 2 bid. My system allows a 2 bid on an 8 trick major one suiter (this seems just short of eight tricks). However, I would not upgrade this hand so I would open 1 and be lucky to find slam.

Phil:

I agree with Phil. We might bid:

Pass
     1
2: Reverse Drury
     3: Slam try, 6+ hearts
4: First or second round control, denies control, denies control (3NT would have shown a diamond control.)
     4: I have the controls that you are denying, I am still interested.
4: I do have a trick source, slam should be reasonable. Let's use kickback (0314).
     5: 1 or 4 (obviously 4)
5: Jeepers! If he has the K, we have 12 sure top tricks and decent odds for a 13th. I will show that we have all keys and ask for specific kings.
     6: I have the K, but not the K, I may have the K.
7NT: If he has the singleton K, then they need to split 4-3 or something else good may happen. If he has Kx, the need to split 4-2 or better. 7NT seems like a reasonable shot.

The key bid is for North to use kickback, which is not obvious, but not that far fetched either.

Opener's 2NT rebid as a slamtry can be used as "Jacoby-over-Drury" whereby Responder can show shortness with a 3-level bid and a "good" outside suit at the 4-level--in a minor for this hand ( much like KenRexford's "picture-jump" ). With neither he can just rebid the agreed Major :

p - 1H
2C!( 3 card limit raise ) - 2NT! ( Jac-Drury)
4C! ( good 5 card suit ) - 4S! ( kickback RKC )
5C! ( one ) - 5D! ( Q-ask )
5NT! ( Q but no K's ) - 6C! ( must be a specific Q-ask; grandslam try )
7C! ( Q and J ) - 7NT ( counting on 1s, 6h, 1d, 5c )

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Fit-Showing-Jumps are ON as a passed hand, but I rather they show 4 card support, since Opener may only have 4 cards for his 3rd or 4th seat opening.

perhaps this is too double dummy butmaybe:


P=2C
3C?=3H
4H=4S(RKC)
5C=5D(q ask)
6h=7h or 7nt?

2c=adjusted 4 loser hand with long major+ more
3c=passed hand max with good clubs
