Scoring: IMP

pass--1
2A--3
3----3
4----4NT
5A--5NT
6----pass

7 took chance of 60%+, would you bid 7? and how?

BTW, do you agree with south's initial pass?

I would pass south hand but would expect 80 % of experts to open it. I would also open 2N so then would have no hope of bidding 7.

Hate to say that this hand works much better with a big club system.

To get to 7 hearts in a natural system, you need to open S hand (which is not so out: 11 HCP, with 2 As and a 5-card suit). Otherwise you will have difficulties in telling N that:
  • you have a max for a passed hand
  • you have a fit in hearts
  • you have a diamond suit

OTOH, you need diamonds 3-2 for a grand (plus a few cases with a fav 4-1). The grand should be around 73-74%, which is not bad at all, but maybe not good enough.

The best solution to get there is not playing Drury :)
If it goes P-1-2 N should be much more active,

Kalvan14: The best solution to get there is not playing Drury



It also helps if you have a more sensible response method to Drury.

1H-2C
2D* *I'm interested. Relay me back to the major and I'll tell you why.
2N* *I'm interested in slam opposite a limit raise.

With this approach, the acution can be:
1H-2C
2N-3H* *Excellent hearts
3S-4D
5D-5H
6D-7D
7H.

However, I would have opened 2N like Justin and had no chance - would feel fortunate to get to 6.

Hi,

I would have passed as South, and I would
not have reached 7H.

Well, I think South's hand is worth an upgrade to 12 points due to the mildly good 5 card suit, the concentrated honors in hearts and 2 aces. Also, opening 1 might make it harder for opps to bid clubs.

But even if South opens, I think it would be hard to reach 7.

The grand is on because South has a 5th diamond, and the suit can be set up for a spades discard.

Unless the methods you use can find out about the 5th diamond, I think it's more reasonable to settle for the small slam.

BTW, I'd open south's hand.

Agree !

I would have played 6 after a 2NT opening and a puppet like sequence.

Is 2NT really a GF opposite a passed hand pard ?

I have always played such kind of sequence as invitational, nonforcing, say a good 13/14 hand.

I will have opened south's hand 1 (26 zar points (11 distributional, 11 hcp, 4 control). And, as most know here, with side weak doubleton and three card support, I would have raised 1 response to 2. It would be very hard, given this start to stop short of 7.

Yes. To bid 7 without knowing of the 5th diamond is a bit of a shot.

Some shots are worth taking, though.

Indeed, but playing the odds is generally the best way to reduce losses in the long run ( including losing partners LOL) :)

An suggested process:

pass---1
2*A---2 *Reverse Drury
3----4
4----4NT
5A----5NT
6----7

Since south passed, so it's ok bidding 6D showing extra length.

You cannot count 13 tricks on any auction except perhaps relaying and even then it might be pushing it. I wouldn't lose sleep about this one.

yes, it's good to have such methods, eh? in the relay precision from gerben's site (assuming south passes)

p : 1c
2d : 2h
3d : 3h (3352 : control ask)
4c : 4d (4 : spiral scan)
etc

but i agree with gerben that missing the grand shouldn't cause a p'ship to fall apart

It doesn't seem that complicated to show AQ,A and 5 after a drury sequence, is it?
