Unfortunately you don't get to see partner's hand before making a bid. Yes, if you knew that west held a rock crusher then you can open 3D, safe in the knowledge that partner will ask for key cards and bid seven. However west's actual hand could have been held by north, or south, in which case you would be happy to open 5D and make life as difficult as possible for them.

A good rule in these situations is immediately to bid as far as you are willing to go. If you were to open 3D would you be willing to let N/S play in 4H or 4S? Probably not. You would sacrifice in 5D. In which case bid 5D straight away and let oppo do the guessing. A further advantage of this is that if partner doubles their contract you can safely pass, knowing that partner knows you have very long diamonds.

Loosely translated that appears to say "anybody bidding a total nonsense 3D is an idiot". And I don't even know what language it was. 😄

I'd call the director on you as my partner if you opened 2c on this. 😉

5D seems like the normal opening bid and one that I expect 90%+ of experts would choose in a poll. Given that, how to reach the grand?

Obviously, any bid of a new suit by responder should be looking for a grand (otherwise, just bid the small slam, as there is no room for exploration). There are two nethods you can use: asking or showing. For a variety of reasons, I think asking is much better when the opener has preempted. If you're going for slam opposite a preempt, especially for a grand, there will never be more questions than: (A) Do you have first (for a small slam, first or second) round control of Suit X and (B) are our trump solid? The showing method doesn't really get you there.

If you use the asking method here to look for a grand, you have to have methods about what suit each bid asks about. Most common over a five level bid is that a bid of a suit asks about that suit up to spades, and then 5NT is clubs and so on. So here 5NT asks about clubs. 6C would show first round control but doubt about trump; 6D would show no first round control of clubs; 7D would show first round control of clubs and good trump. Since you can't have AKQ of d and Ac and open 5D in first seat, opener should just bid 7D over 5NT. How could he ever have any more than KQd and Ac? The other way of looking at it is that if partner lacked BOTH the AKQd AND the Ac, he has no business making a grand slam try.

That's an interesting way of reaching the grand, Mike. Thanks for posting it. Personally I haven't seen this method over five level pre-empts. There again, the chance of holding a 9 card suit is about 1 in 2600 or thereabouts, I believe, and partner enquiring about slam remotely higher, so I'm bound to have forgotten it by the next time I need it. Just my luck

The newish players in our club would bid

1D - 1S
3D - 4NT
5S - 7D

and wonder why they got such a good score.

 dickiegera, on 2017-October-11, 08:16, said:

I think opening 5D is ok according to rule of 2 & 3
The problem2 is only quality of trump suit. My opinion is to bid 5NT to ask partner for top honors.
5D - 5NT
7D yes 2 of 3 top honors.

Probably not over five-level preempts, but it's really a logical extension of the more standard jump rebid control asks you've seen over 2, 3 and 4-level preempts. Most folks are familiar with auctions like

2M 4m
2h 3S
3m 4M
4H 4S (if not Kickback)
4M 5m

and the like as control asking bids. Over 2M, for example, a bid of 4m has no real use otherwise (you can bid 3m if forcing first, or 2NT first with the normal type of hand). Same with 2h 3S (can bid 2S if forcing or 2NT if not first). Same with 4M preempts.

The reason is that a preemptor (especially at the 3 level and above) has narrowly defined his hand. You don't want to show him what you have; you want to ask him to narrow his hand even more so you can basically see both hands. Indeed, if you are interested in a slam, you must have first round control of at least two of the three side suits to investigate a slam. If you have that, and if you clearly have the tricks for slam, what you generally want to do is ask about the preemptor's holding in the fourth suit. There are a number of ways to play responses, but you normally have to be able to show first round control, second round control, and no control, and then for a follow-up ask, you want to be able to distinguish the high card (A or K) from the distributional control (stiff or void). You probably also want some way to be sure your trumps are halfway solid.

There's no reason why this shouldn't extent to bids over 5-level preempts as well.

Cheers,
Mike

You have some very good "newish" players then! In my experience most would open 5D ("I only have 9 HCPs, partner, but I do have 9 diamonds"), or if they did open 1D they wouldn't rebid 3D. And most Wests might opt for 2S over 1D, or a final contract in spades or no-trumps as "they only have one diamond".

I'd bid 5D-5S; 6C-7D. 6C has to be a first-round control at this level.

Maybe, but two of them (out of two asked) yesterday separately thought this was the obvious auction.

And next time opener will have the Q♣ rather than the A♣!!

Frankly speaking, it is the ninth card in diamonds which is causing difficulty in bidding.We open 5D only with a rule of minus 500 in mind and purely preemptive.So we open this hand only 1Diamond.But I am not afraid to admit that further bidding is pretty hypothetical.Even the Precision MAESTRO may not be able to find a systematically agreed bidding sequence to reach 7Diamonds.It is easier to bid it when we see all 26 cards ,isn’t it?

In this cards layout, meaning, East is the dealer, and none is Vul the final auction should be 7NT no matter the opponents cards distribution.
But if North is the dealer and holds 8 Heart cards and 6 HCP, he would bid 4♥, and east should PASS. West would bid 4♠ and the auction will end with 5 by East.

Here is one option for distribution:



.

Playing GIB 2/1 the auction could go:

1 ♦ 2♠ (Soloway jump shift)

3♦ 3♥ (forcing)

4♦ 4 NT (RKC)

5♠ 7♦

2 problems. Responder is equally likely to bid 7 NT, and everyone I know would open 5♦. (So I like Miamijd's solution).

I can't imagine anyone passing over 4H on the east hand. However, if someone did, a subsequent bid of 5D over 4S would be a slam try agreeing spades and showing a diamond suit. Something like Kxxx x AQJxxx xxx

 GrahamJson, on 2017-October-13, 09:25, said:

Regardless of what 5♦ after passing shows, I cannot imagine west with a hand most of us open 2♣ passing 5♦ over 4♠. Once west bids 5♥ showing great slam interest and a cue, the pair should at least reach 6♦ and hopefully 7♦ after the 6♣ cue to follow.

 GrahamJson, on 2017-October-12, 06:42, said:

I admit this would have been my auction, as well. I don't know of any standard treatments that I would expect most advanced players to know.

 dickiegera, on 2017-October-11, 08:16, said:

For high level preempts you can simply replying in turbo fashion.

1st step even
2nd step odd no Q
3rd odd+Q no extras (we might have all the keycard but only 12 tricks)
4th odd+Q extras/sources of tricks (meaning if we have all the keyc we need to be in 7)
5th to play

At the 5 level VUL you can probably ignore the Q of trumps and save a step.
