How should bidding continue?

We play inverted minors.

Thank you[/hv]

What is 2♦ in your system?

[jdonn]

And if we start 1♦ does opener rebid 1♥ or 1NT in your system? And if he rebids 1♥ do you play 1♠ or 2♠ as 4SF or XYZ? And if he rebids 1NT what type of checkback do you play?

 

What is your system pleasssse. All I can say for sure is I would not start 2♣! I probably start 1♦.

[mikeh]

here is one method

 

1♣  1♦

1N  2♦ art gf

2♥  3♦

3N  4♦

4♠  ?

 

Maybe S can bid slam now, but will probably bid 5♣. Whether that gets N to bid slam is an open question. He does have 2 Aces, when he might only have had one, but he surely can;t have a much worse hand and open.

 

Note that this 1N rebid by opener assumes a walsh style approach.

 

If N will rebid 1♥ over 1♦, then use 4th suit and then bid diamonds and proceed more or less as above.

 

S cannot afford to ever use exclusion...reverse North's majors to see why.

 

This isn't a great slam presuming the opps lead effectively...what maybe makes it ok is that it will usually make simply on the lead. A club gives it to you. A spade from KQ increases your odds since now someone with 4 spades may be in trouble on the run of diamonds. A heart will generate make life easy (ruff the first one, draw trumps, cross to dummy, run a heart, pitching a spade...win the return and cross to dummy and pitch 2 clubs.

 

So in practice, this slam is probably over 50%.

1C 1D

3N 4C(cue)

5C(cue) 6D

all pass.

3N

 

looks likely to me.

 

Oh well, missed another really good slam. At least my auction advertised a spade lead which makes it only a so-so slam!

I like J-Lo's self(3♥!)-splinter for Diams..... but he's probably right that Opener won't cooperate with a 3S cuebid.

2♦ I guess would be pre-emptive

We play that 1♣ - 1♦ gets a 1NT bid unless opener is unbalanced.

 

And then we have a problem with what would be a forcing bid.

2♥ & 2♠ would be forcing however they could hardly be used here

Hi,

 

1C - 1D

1H (0) - 2S (1)

2NT (2) - 3D (3)

3NT (4) - 4D (5)

4S (6) - 4NT (7)

5H (8) - 6D (9)

 

(0) I was assuming SAYC, and I think in standard the response is 1H instead of 1NT

(1) FSF, inv.+ / I dont think it makes any difference for the following, if you play FSF as GF

(2) Stopper, in the context of inv.+ it also showes min.

(3) GF with long diamonds

(4) what else? One has a douple stoppe in hearts, spades and clubs, and a min

(5) slam interest, setting trumps

(6) showes a control, denies a top honor in hearts

(7) because of (6), p wont have the Ace of hearts, so RKCB is safe

(8) 2KC

(9) either (2) or (3) showed a min, so no reason to look for more

 

With kind regards

Marlowe

You could bid 4D, the obvious downside being that you are by passing 3NT.

One has only 12HCP oppossite a 12-14NT.

Responder basically needs to decide, if he wants to go looking for slam, risking

to play 5D, or if he signs of in 3NT.

The alternative is, that you play some form of (two-way) checkback stayman,

which would cater for the given hand, or for a minor two suiter.

 

... And the suggested 3H self splinter is certainly a good idea, although I am not

sure, I would try it out undiscussed, auto splinter, is something I dont have in

my repertoire at the moment.

 

With kind regards

Most auctions probably end up in 3NT:

 

1♣ 1♦

1NT 2♣ (forcing)

2x 3♦ (6 cards, game forcing)

3NT

 

now what? Given pard has good stops in the majors, pass is very sensible.

You really should work on your system, if you have no forcing minor suit bids after 1 NT. :)

 

I think you should play 1 club 1 Diamond 1 NT 2 club as artifical: weak with diamonds, or strong hand which you show after partner relayed to 2 diamond. But theere are other great systems out there too.

[hrothgar]

The following seems like a fairly reasonable start

 

1♣ - 2♦

2N - 3♦

3♠

 

1♣ = standard, 2♦ = SJS

2N = balanced hand, 3♦ = self sufficient suit

3♠ = first or second round Spade control

 

When opener cue bids 3♠ and denies the A/K of hearts, you're off to the races...

Unless you have a special treatment, Opener will rebid 1H over 1D :

 

1C - 1D

1H - 2S! ( let's say you use this common treatment as 4thSGF )

2NT - 4D ( jump sets trumps and demands a cuebid )

4S (denies a Ht Ctrl ) - 4NT ( partner has denied Ht Ace, so key cards will be black )

5H ( 2 - dQ ) - 6D

This.

[gnasher]

Most of these sequences seem to rule out the possibility of playing in clubs. That might be unwise: Axx QJxx xx AQ9x makes 7♣ pretty good (and only slightly worse than 6♦).

Good point on the Club suit:

 

1C - 1D

1H - 2S! ( 4thSGF )

2NT - 3C (at least 4 cards )

3NT - ?? will Responder go past 3NT with 4D....

and if so, will Opener cooperate with a 4S! cue ?

[JLOGIC]

Most of these sequences seem to rule out the possibility of playing in clubs.  That might be unwise: Axx QJxx xx AQ9x makes 7♣ pretty good (and only slightly worse than 6♦).

There is also the subset of hands where partner has the SK and we need to rightside slam by playing 6C.

 

In your example is 7C really only slightly worse than 6D? It seems like you will often guess who has 4 clubs on 4-1 clubs in 6D, or you might just get a stiff club lead from LHO. In 7C you can only pick up 4-1 clubs one way.

 

Also I think 7C is in more trouble on 4-0 diamonds than 6D is assuming they'll lightner double with a void and you're down on 4-0 diamonds offside if clubs go 4-1, and also if they find a heart lead even on 3-2 trumps. Whereas in diamonds you can pick up half the 4-0's at least.

 

This hand is pretty complicated. There are many concerns like:

 

1) Stopping in 3N when it's right

2) Bidding 5D or 6D when it's right

3) Finding clubs when it's right

 

I think everyones main priority is #2, rightly so, that is the most important issue. Some auctions deal better with 3, and some auctions deal better with 1 (indeed many of these auctions are just driving past 3N singlehandedly). It's hard to construct an auction that handles all 3 adequately. Maybe focusing on clubs at a lower level will allow partner to evaluate his clubs and keep 7C in play while also keeping 3N in play eg.

 

1C 1D

1N 2D

2H 3C

 

But what auctions are we comfortable passing 3N on now? What are we doing over 3D, 3H, 3S, 3N by partner?

 

I think giving up on clubs is pretty reasonable and just showing D+short hearts and letting partner decide. If partner has heart wastage then slam is usually out of reach. I think QJT9 is an unlucky holding, it's enough that partner will bid 3N but it's not really that much wastage compared to what he could hold.
