BId this using 2/1 - progressive

[Winstonm]

Partner bypassed 4♦ denying a diamond control.

Partner would not splinter in your suit - clubs.

Partner, with AKx, Jxxx, QJxxxx, void would have bid 4H over 2H (fast arrival principle)?

[jillybean]

It would be great to be playing some serious/not serious slam gadget but what to do if not having that option?

 

Over 3H I will bid 4C. I assume partner bids 4S. This should be a cooperation, not a forced response, yet pard can’t be certain about trumps so I expect good ones and a reason to think slam is likely. AKx, QJ96, KJxxx, x

 

I don’t think I can find out about the spade king and pard could not go past 4H without a diamond control so I think I will settle for 6H over 4S . GS is possible but I don’t think we can find out enough to bid it.

Is partner not free to cue above game without D control now that the partnership have made their first cue bid 4C?

 

Partner, with AKx, Jxxx, QJxxxx, void would have bid 4H over 2H (fast arrival principle)?

Yes, or I'd like to think so. :)

Here's the full hand, the auction was not ours but I was asked to look at the hand.

One pair bid and made 6H, one pair was allowed to make 6nt, and one pair got to 6C but went -1 Everyone else stagnated in 3/4nt, or 4/5 hearts.

Yes, this says a lot about the level of play.

[mikeh]

If 4S denied a diamond control, then it was a terrible bid.

 

There is no hand I can construct where responder should force beyond game, merely because responder made a mild slam try, with no diamond control.

 

Bear in mind that all we’ve done is to announce that we have mild slam interest, and he’s already announced some extras by not bidding 4H over 2H.

 

If, therefore, he bids 4H over 4C, we’re not playing him for a hopeless hand…that would have bid 4H rather than 3H.

 

I can’t construct a hand on which he has no diamond control and we lack 5-level safety so I would have bid keycard over 4H (for me, 4S since I play kickback, but 4N should be safe if that’s your keycard)

 

Bidding 4S with no diamond control is strange, not to mention bad. Why do we have to have this hand?

 

AKx QJxx QJxxx x is great when we hold this hand….not so much when we hold Qx A10xx xx AKQJx, and have told the opps to lead diamonds

 

That hand, 2=4=2=5, is worth 4C since opener might hold say Axx KJxx Axxxx x and 6H is excellent even on a spade lead….fly the Ace, cash top hearts, and play clubs from the top. Hearts 3-2 and no opponent with a stiff club, and we are close to claiming…well over 60%. Or duck the spade, then safety play trump if that works, otherwise hope hearts are 3-2 and we win the hook…% depends on the propensity for the opps to lead away from the spade king, on an auction that probably suggests a spade lead (although it gets complicated if there was a chance to double a 4S call).

 

Since first drafting this, I’ve seen the hand. So why can’t responder hold Qx AJxx xx AKQJx….an even better 4C cue holding….and once again we’ve told the opps to lead diamonds. Now even the 5-level is decidedly unsafe.

[Winstonm]

Is partner not free to cue above game without D control now that the partnership have made their first cue bid 4C?

 

I can only answer based on how Bob and I used to play.

 

It all depends on the strength allowed for the initial slam try. If it can be somewhat mild, then opener should not cue bid 4S without a diamond control because responder has not shown that control. If responder has a "serious" slam try, he will cue again after the sign off. Note, if opener bids 4H over the 4C bid, he denies a hand that looks valuable for slam purposes, not any particular control. With a hand that is more slam inclined, 4D is available if that control is held.

 

Please understand that we played before the advent of things like Last Train so our arsenal was comprised of cue bidding and keycard. I like to think it honed our judgment, but I may just be fooling myself.

[jillybean]

Ok, we have not honed our system to include mild or serious slam tries. Everything is a slam try.

With partner making a mild slam try (4♣/3♥), 4♠ would show first round, not second, ♦ + ♠ control?

[DavidKok]

Responder has failed to bid 3♠. Therefore classically 4♦ shows a ♦+♠ control and 4♥ denies having both (but may have either one). A very annoying situation. Exploring which control is missing (it is very improbable opener has neither) may well take the partnership beyond the safety level - opener could well have ♠xxx♥QJxx♦AKQJx♣x or the likes and the defence might take the first three spades.

 

The direct 4♠ is not much better, because it is guaranteed to take the partnership beyond 4♥ (failing if responder has longer empty diamonds). But I don't see a good solution either (well, last train).

[mw64ahw]

Using the 1♠ GF gadget was an approach I picked up from fromageGB. It provides extra bids to shape out and show strength compared to 2♣

 

In this case:

1♦-1♠ GF

2♥ (4♥6+♦ Min)-3♥ SI (with an MLT of 4.5 this is well within bounds otherwise just place the contract)

3♠ (♠ control)-5♣ (3KCs w. ♣ & ♦ controls and at least 1 ♥ honour)

6♥ (We have the combined strength to make the small slam)

 

Using 2♣ as GF I would bid 4♥ denying the ♦ control or 2♥ honours. North has the strength to then continue the slam bidding.

 

So far I've avoided using frivolous/serious NT/Last train as I find the nuances a touch opaque.

Partner has to be thinking not simply bidding. What does partner know? A slam try has been made without a spade control. That should mean good trumps. Pard has cue bid his long suit - sounds like a pretty good suit, a source of tricks. Opener’s job now is to tell partner if his hand is suitable for slam. AKx, xxxx, KQxxx, x 4H the heart support is too weak.

 

KJx, QJxx, AQxxx, x 4D ok and I have diamonds controlled

 

So, what would 4S mean? At worst, AKx, Q9xx, KQxxx, x

 

With two aces and the queen the bid would be 4D

[Gilithin]

Responder has failed to bid 3♠. Therefore classically 4♦ shows a ♦+♠ control

Classically it would have shown first round control, thankfully very few pairs still use classical slam methods. In modern bidding 4♦ typically shows a ♠ control and denies the ability to go beyond game. That will often be because of a missing ♦ control. Standard modern slam bidding methods are actually pretty complex for most club players and there are simpler alternatives that achieve a similar effect without needing so many special rules and inferences. That such a simple auction as this is already open to so many shades of interpretation without specific agreements in place is an example of the issues that can easily arise.

[Gilithin]

You don't need to find out about the ♠K below 6♥ on hearing 2+Q, you just need to stop in 6♥ if it's missing. So pull out your king ask and proceed to 7♥ (or 7NT) if partner produces the spade king.

You miss the point, the king ask is 5NT so let's say partner shows the ♦K with 6♦. Now what? Even if partner only has the ♠K, most pairs play that showing a king above the trump suit is optional so there is no guarantee that you will hear 6♠ rather than 6♥. And that is even without considering partner holding a singleton ♠A or ♦AKQ. It is just very difficult to cover all of the various possibilities with any certainty.

[mw64ahw]

There seems to be a lot of over thinking here.

If South's denied a ♦ control there aren't a lot of hcps left to hold i.e.

AK♠

QJ♥

QJ♦ max.

Take out K♠ and South is opening light with 10hcp. If 4♠ is Kickback then continue cue-bidding with 5♣ (also the Kickbo bid if you use that approach) instead of asking for KCs to clarify if partner has K♠. Skipping 4NT as a proxy for ♠ control says bid the slam if you have a the ♠ controls we need. With a duff ♥ suit or w/o K♠ sigh-off in 5♥

[DavidKok]

And that is even without considering partner holding a singleton ♠A or ♦AKQ. It is just very difficult to cover all of the various possibilities with any certainty.

Ah, for me 6♦ would show the king of diamonds or the other two kings (not possible here), in particular it denies the king of spades. 6♣ would show the king of clubs or the other two, i.e. the other two. And 6♠ shows the king of spades (or the other two) and therefore denies the king of diamonds, but that's fine since we can count 13 tricks.

1♥

 

The benefits of "2/1 GF" apply to a major, but not a minor. Over a balanced club you want to describe your hand, and over an unbalanced diamond your priority is to find your fit or hear opener's shape. 1♥ is forcing if you want to play "natural", and I have no problem with forcing to game after that, so you do not need a GF bid.

 

1♦ 1♥, 2♥ - this shows 4 card support, and a common gadget after major support is 2M+1 to ask for strength.

 

1♦ 1♥, 2♥ 2♠, 2NT - his step1 shows 12-13. (Step2 would be 14/15, etc.) As opener is unbalanced the most important thing to find out next is his short suit, so next step asks :

 

1♦ 1♥, 2♥ 2♠, 2NT 3♣ - There are 2 suits it could be, so using "low/high", step1 shows short suit in clubs.

 

Normally the next most important thing is to discover whether singleton or void, so next step would ask for that, but here with my clubs I am not bothered. I can see a 29 count excellent fit so slam may be possible, but I am concerned about my spades. I need to cue to discover a stop before ace asking.

 

The concepts of "non-serious" and "grand slam try" do not apply when partner is well defined, so the 3 bids below game can be assigned as 4M-3 / 4M-2 / 4M-1 for controls of the "low", mid", high" side suits. I bid 4M-1 to ask for control in spades. "Control" is any of void/singleton/A/K. If partner does not have that control he is forced to sign off in game, but if he has control he is forced to deny a higher control (if there were one), or show his ace response as if asked with the normal 4M+1 ace ask.

 

1♦ 1♥, 2♥ 2♠, 2NT 3♣, 4♦ 5♣ - 2 steps above a 4♠ ask shows 2 crucial cards (AAAAKQ) so I know he has spade control and 2 keycards. We are missing an ace (or trump Q), and if an ace I do not know whether diamonds or spades. A missing diamond ace is of no concern, but nor is spades as we have KQ, and any other losers in that suit can be thrown on my clubs for a ruff.

 

1♦ 1♥, 2♥ 2♠, 2NT 3♣, 4♦ 5♣ , 6♥

 

6♥ is looking solid.

[jillybean]

Playing 2/1 or std, I want to bid my 5 card ♣ suit before my 4 card ♥'s.

 

All of these detailed agreements are fine if you have a partnership willing to put in the time and effort needed to master it.

I don't have that, so keeping things simple is important right now.

[nullve]

Maybe

1) Assuming a style where 2♥ would promise extras

2) Splinter (what else?)

3) cue

4) RKC

5) 0 or 3 key cards

Nice but..

Should you splinter in partners first suit?

South does not have a diamond cue.

You need agreements on your cues, we won't splinter in partner's suit on your first cue, so would not bid 4♣ which absorbs way too much space anyway, and partner with ♦AQJxxx knows you have the K rather than a stiff with 4♦. N has a VERY difficult bid if he can't bid 4♦ over 4♣ however and it may be least of evils, but this is part of why 4♣ is not a good bid.

 

Our full auction would be something like

 

1♦-2♣

2♦-2♥(kinda 3rd suit forcing not GF artificial)

2N(5+♦4+♥ minimum ish)-3♠(bid 3N with a spade stop, or agreeing hearts slammish if I bid on over 3N)

3N-4♣

4♥(no ♦ cue]-4♠(Kickback)

5♣(1/4)-5♦(Q♥?)

5♠ (yes and ♠K)-6♥

[fromageGB]

Playing 2/1 or std, I want to bid my 5 card ♣ suit before my 4 card ♥'s.

Ah! I guess I am in the mafia camp as for me it is majors first (cheaper). Should opener not have 4 card support he describes his shape and then I will see where to go.

[Winstonm]

Nice but..

Should you splinter in partners first suit?

South does not have a diamond cue.

 

I do not believe a splinter in partner's suit is a good idea - as a source of tricks it makes more sense to cue bid secondary honors, filler cards.

[Winstonm]

Nice but..

South does not have a diamond cue.

 

Here is my interpretation of how this would go. I don't think there is anything unusual here to remember.

 

1D-2C

2D-2H

3H*-4C *this hand has controls, shape, and decent support, so not fast arrival.

4H*-5C* * sign off is required as no diamond control. *I have diamond control and good clubs and hearts.

5S*-6H* *OK. I have what it sounds like you need - spade controls. * I am missing the the diamond ace.

 

PS: Note that Kickback and Keycard are totally absent, but a little judgment is required.

[jillybean]

Thanks. As you say, nothing unusual, it's a logical conversation.

Exactly

[Gilithin]

I see the conversation a little differently to be honest. First of the auction up to 3♥ should be non-controversial, regardless of whether the system is 2/1, SA, SEF or Acol. After 3♥ methods come into play. First of all the basic system Winston was working with. 4♣ is clear and since South's first job is to limit their hand I can support the 4♥, after which 5♣ is again clear. This is where I disagree though - North has denied a spade control here so without one South would automatically bid 5♥. So I think 5♦ here should be a form of Last Train and explicitly deny a diamond control, with any call above 5♥ showing controls in both. So my preference there would be a 5♦ bid instead of 5♠.

 

Things are a little different if we are playing Frivolous 3♠/3NT; now 4♣ is a Serious cue and South's first job is to show or deny a spade control. In this case the bid is 4♦ rather than 4♥ using the same logic as after 5♣ in the previous auction.

 

Similarly for Serious 3♠/3NT. If North bids a Serious 3♠, South can show the spade control with 3NT and the rest is easy. If North instead bids a Serious 3NT, South can show the spade control (and club shortage) with 4♣ and again things will work out.

 

Finally, using Frivolous 3♠ and denial cues, North can bid 3NT over 3♥ ask about spades while showing serious slam interest and South continues 4♦, once again showing the spade control and club shortage.

 

You will notice that the more advanced methods require more memory but a little less actual judgement/luck than the basic methods. Which is easier to play is something of a matter of taste.
