2/1 context...... but use any bidding system you like.

Our unenlightened bidding went:

4H ... making 12 tricks

Only 2 tables reached slam with a "leap of faith" bid of 6H over 2H.

I don't think I'm reaching this one, but if I did, it would be.

1-1
2-4(usually a splinter, but gives you a decent out over 4, and you can pass 4)
4-5(nothing else to cue, but interested in slam)
6

Always awkward when you're short in partner's (bad) bid suit.

Life is easier if you support with support. My auction:

1-2(GF, clubs VERY suspect)
2-2(hearts agreed)
2NT(not two top hearts)-3(not two top clubs, diamond card)
3(one top heart)-3NT(serious without spade control)

At this point, Opener MUST know that Responder has the club Ace, two top hearts, and the diamond Jack, if he is "serious" within the context of what he has denied. Slam, therefore, will turn on something developing in spades, or the club Jack, or the club 9, or some squeeze, or whatever. RKCB to the end. Note that Exclusion is unnecessary when Responder denied a spade control.

Does
1H-1S-
2H-3C force?

So over 3D, 4H gets my good support and C-control into this auction?

Would much rather have seen a 2 rebid by opener, this hand is nothing to be ashamed of.

With given bids though:
1-1
2-3
3-3
3 (hopefully shortness on the auction)-4 (losing some lesser honors' value, but its not like we have KQ10xx in spades)
4 (furiously trying to catch up with my hand)-etc

If we can rebid 2:
1-1
2-3
3-4 (should be cue for hearts, excited opposite opener's good 6-4, and now we get there easy)
I once yelled at my partner for discarding the 'wrong' card when he was subjected to a squeeze that I allowed by giving the wrong count with too high a card. Now he's allowed to pitch aces when the opponents have the king in the dummy. At trick 2. When he could have followed suit. And blame me.

I like 1H-1S-2D much better. With 6-4, both suits of good quality, and a hand that is not minimum, 3D is a better rebid. That gives responder a chance to appreciate diamond fillers and also to find out that opener is not a balanced minimum. Depending on style, 2H rebid by opener could be something like xx-Qxxxx-AKx-QJx in which case 4H is plenty high enough!

I also dislike the 2H rebid.

Since kenreford started it, I would also respond 2C instead fo 1S. Opener would then show a 0643 shape with (eventually) 4C and I think responder would just ask for keycards in hearts.
and the result can be plotted on a graph.

As already said by many others, I think 2H by South is a pretty serious underbid. After 1H-1S-2D there's at least some chance of being able to catch up later if a fit surfaces.

And as I've said in many other threads, there is a reason why I play 1H-1S-2D-3H as natural and forcing, relegating the 12-pointers to FSF rather than having bad slam auctions on hands like this.

After that start and 3S-4C-4D cuebids, there's at least SOME chance somebody will figure out the trumps are solid and bid the slam (but finding out for sure that there is no diamond loser to go along with the missing CK is hard.)

Here are 2 other concepts ( from my notes ) to solve the GF bid problem for Responder. Subsequent bids still are not easy:

1) Meckwell:
1H - 1S
2D - 2S! ( they treat this as an artificial GF )
3H - ??

2) Bill Higgins has suggested 2S! as a limit raise+, "fit-showing-jump" with 3 cards Hts ( Jacoby 2NT, or some such, would be a GF w/ 4 cards ):

1H - 2S! ( let's say it should be GF w/3h )
3D - 4C ( cue; denying Sp Ctrl )
4NT( not worried about Voidwood since no A,K w/partner) - 5S ( 2 + hQ )
6H

An artificial (2xClubs. Natural must promise 3+clubs) 2C GF?
Now what would the 2D GF look like in contraposition? How different from 2C GF? Surely not also 2xD?
Artificial some other way controls /trumps / points? Develop these like Swiss raises?
What rebids then show real 4-5x clubs or 6+clubs --the real suit cases?

1H (1) - 1S (2)
2H (3) - 3D (4)
3H (5) - 4C (6)
4D (7) - 5C (8)
6H (9)


(1) 2/1 context
(2) we would bid 2NT as Jacoby, but most likely you require 4 card supp.
(3) I would prefere 2D, espesially if it promises a 4 card suit
(4) values, but can be improvised sometimes
(5) nothing else looks better, denies 3 spades
(6) agreeing hearts, slam move, not 100% clear, if it promises a control
(7) Cue, showing a top honor
(8) Cue, First round control, ..., the diamond cue made the hand stronger,
one will face at best a spade doubleton, the cue denies also 1st or 2nd
round control in spades you dont have to bid this, but if you dont open crap,
the 5 level should be reasonably safe, and stopping in 4M without making
another move would be very timid, but usually not the brave come back home
from the war.
(9) AK in diamonds, spade void, this needs to be enough

The key bid in this sequence is 5C.

With kind regards
Marlowe

PS: It is funny, that peoble insist on playing 2NT as GF raise with 4 cards,
start a flame war, if someone suggests to weaken the req. for 2NT, and later
on invent new conventions to show the GF raise with 3 cards, one would
think that responding hands with GF values und 3 card support are more freq.
than hands with GF values and 4 cards. - I could not resist, as I have read the
amount of comments suggesting new toys for hands with GF values and 3 card
support.
With kind regards

ONEferBRID,

Instead of looking at one hand and choosing the methods that would work on this hand, I think that you should pick good methods to play, and then look at how you can bid the hands well within this method. Given any two hands you can always find a method that works for these hands and then say, aha, look how good the method is! That doesn't work, and no agreements work best for every pair of hands.

Having said that, I think the meckwell idea is very good.
and the result can be plotted on a graph.

It depends on who you ask. For my part, clubs is natural UNLESS Responder's next call agrees Opener's first suit. With clubs AND agreement, there are some fit-jump options later, to help the cause.

Diamonds are generally natural.

If you could handle a short club opening, or a Gazilli-like short club rebid, then you copuld probably handle this 2 call also.

For me, the natural auction would start 1H - 1S - 2D - 3C - 3H - 4C. I only mention it because noone else has given this possibility. Having a gadget that allows the auction to become forcing and agreeing hearts at the 3 level would be beneficial. Responding 2C works great on this hand but there are lots of other hands where it is not so good. In the past Fred has pointed out some dangers of using 2/1 on unsuitable hands just to establish the game force.

Does nobody play
1 - 1
2 - 3 as game forcing?

Mind you, it doesn't really help for this hand...
