发帖数: 31 | 2 Playing on Morehead City Sectional Tournament NC last Saturday. I had two
wonderful games with my partner, average 62.5% we wont the two session

of them. This is one of the four slams.
My hand was: (S)
S: XXX
H: J
D: AKXXX

Partner's Hand was:
S: AXXXX

发帖数: 623 | 3 2S slam interest and 2NT transfer doesn't seem to be
coherent. After minor staymen or transfer you have plenty
space to show slam interest.
More technical details. A few methods that are popular
today:
1. 2S MSS or D bust (if after 2S, responder rebids 3D, it
shows a garbage hand with long D suit). 2NT transfer to C
(sign off) or 4-4-4-1.
2. 2S, 2NT transfer to C and D respectively. Opener can bid
one lower to show super-acceptance. Eg. 2S-2N shows super
acceptance in C.
3. 2S transfer to C or D |

发帖数: 3714 | 4 blush.. it wasn't my idea to bid 3S, actually this is not my style too..
but with 6 loser and good suit this is a reasonable try from my point of view.
I think S should open 1H, and show strong later. 2NT implies no 5 major,
which may cause trouble when S-N are trying slam later.
S shouldn't bid 2C, since he has too many losers. In this situation,
it is reasonable for N to try slam because N was mislead by S. |

发帖数: 623 | 5 The problem is you may endbid pd. He may not know what to do with 1-5-4-3
shape, or even 2-5-4-2 shape, with 10x S. And he may have to temporize with a
3H bid. Then you may not know whether to raise him in H, bid 3N, or bid 4D.
Bidding 3D directly, however, is helpful in finding the D slam, but the slam
will only be good if he has a singleton somewhere, or he has 5D (in which case
he also has singleton). But in this case, partner's hand is easier to
describe, and it may be better for you to take |

Back to the question raised, my question is if North holds solid diamond suit,
plus medium club support (Kxx, Q9x, or 10xxx), slam interest in either club or
diamond, after 1D-2C, what will you do?
I think in that example 1D-2C-3D-3NT, 4H must be a cuebid, in that sense, he
might want a spade 2nd round control (otherwise, blackwood will be much better
if he holds both heart and spade control, slam will almost be certain). I

发帖数: 3277 | 7 I would just bid 3NT with your hand, because it's MP and chance for slam
is remote. you need pd to hold something like:
Sx HAxxx DAx CAQxxxx to make the slam.
I don't really think 3S here shows sp stopper. It should be asking for
sp stopper. |

发帖数: 3277 | 8 over 1D 2H
2S: showing C support, relay as I stated above, forcing to 4C
2NT: relay to 3C, later we can sign off in D as well.
if we bid 3H/3S, that shows a semi-solid or solid D suit, at most
one loser. also a cuebid, trying for slam.
if we rebid 3NT, that shows balanced hand, 6 good diamonds, inivting
slam.
3C: shows C tolerance with 6+ D suit.
responder can be 3D with fit. cuebid 3H/3S: with good C and value.
or sign off in 3NT with bad C and no D support.
3D: show |

South:

East pass, real bidding is:
South North

2C 4H

I think 4H is the best for this hand. But I feel it is not the right way to
bid this hand. Because south has a too good hand to give up slam try.
My question is: what is the right bidding sequence for both N and S that will
explore slam and still safely stop at 5?

发帖数: 3277 | 10 well, the score format is IMP, so there is no top or bottom here,
+500 should be a reasonable score. Tops and bottoms are for Match point,
not IMP. Anyway, I wouldn't pull the double if your partner's double is
for penalty. if it's take out, it would be a tough hand to bid,
that's why some players play good bad 4NT here.
4S x p 4NT: shows slam interest in H or D, or sign off in C.
4S x p 5C: slam interest in C.
4S x p 5D/H: to play. |

The question is whether I should bid slowly or fast. I think there are several
reasons to take the slow path: 1. I had the master suit; 2. Even if they found
a save my 2 A's rate to take 2 tricks, and I don't have to worry too much
about double game swing. 3. Facing an average opening hand, this may actually
produce slam. For example, KQx KQxxx xxx Ax, slam |

Seems 1H is definitely not a choice for your guys. :-)
what's wrong with 1H? I bid 1H because I have 5 hearts, very simple.
In reality, I believe, if you do want to reach the slam, probably
you have to go through 1H, not some other Hi-tech aritifical sequences
which nobody could understand.
Or, maybe you could reach the slam simply because at five level a fit
has just been found, so raise to show it. |

发帖数: 545 | 14 This the question i raised quite some time ago. Last night when I reread mike
lawrence's book on 2/1. His opinion on 4card major vs 5card major is that both
have their merits. In partscore and game contract they are basically even. He
said, it is in slam bidding which 5card major outguns 4card major.
This remind me of the precision club. I think precision has exactly advantage
in slam bidding. So this seems to imply that precision with 4card major will
be even better.

I quit subscribing to it this year. The new format reduces the juice of it...
Is it by any chance online?
In general are there good ways to bid with a 6 card major, to seek for a slam
(it wouldn't be a big issue if 4H/4S is the goal)? Smolen is for two majors,
yet it is very important, for slam to be possible, to know the 1N opener's
trump support when you are single-suited. |

good point---3D shows nothing but a suit preference
of the 5+d promised over the 4 spades promised in 1d-2s.
i.e. South's having one Ace doesn't necessarily lead to
a slam.
Moreover, North (of course not North with THIS hand) could
even pass 3D. 1D-2S doesn't promise a game. So if I were
North, based on such a 3D(passable) plus the 4C later(that
shows slam interest), supposing they are consistent, there
would be a 6 without ace asking, but no 7 (without ace asking either).
But isn't 3S a non-fo |

发帖数: 3277 | 17 4S is fine. north should have passed 4S.
5C would be an overbid, because your diamond suit is quite weak,
partner would usually bid over 4S with SAxxx Hxx DAKxx Cxxx
The major problem of this sequence is 4NT which is clearly an overbid.
Since partner can't cuebid 4H or 5C, slam should be remote. 4D has shown
some slam interest and north's hand has no extra, so the right action
is to pass 4S.
If you have HQ DKQ and CA, you would cuebid 5C for sure.
If you have HA DQJ and CA, you would cuebid 4H. |

honestly, don't know what happened. his cue show slam interests, even with
your limited 1nt.
your 4c cue and confirmed slam interests.
but he jump to 5d looks like he is searching for S fit.
guess he has like 3460. and your H support with double S is nice here.
I will raise to 6d. |

4c is wrong. Usually, only cue when you have EXTRA.
for your hand, your extra is double fit, not extra point/strength.
besides, you have too many points in pd single or void S.
and, your H is too weak.
so 4D is the only choice for you.
Pd's hand looks pretty, he will try 5c to show slam interests.
your SA looks nice in this case.
Myself prefer 6d directly after 5C, since you have no extra for grand slam and
feel very satisfied with 6d.
Obviously, your P have no HA, since he cue 5c, after 4d.

发帖数: 623 | 20 I don't think so. 4S would be an overbid. Opener can reverse the S with D and
you do not have safety on 5 level. And in fact, in that case, 4H is the last
making contract.
This is a case where cuebidding at 3 level will help greatly. As you can see,
responder has no serious interest in going to C slam to begin with, cuebidding
3D would help. Now a cuebidding of 3S will either show doubt of 3NT or real
interest of C slam (in which case, he could pull out from 3NT). Opener will

Besides, Given we play 2/1. 4C needs not to be very strong.
finally, I choose pass.
For this hand, what I prepare is if P 4nt, I have a perfect 6C.
If p 6c, I will 7c.
if P 5c, I pass.
I admit, C slam is the most difficult here.

This is a rubber game and both vul.

with a hand with a side A and trump AK, definitely go :)
that is in the high end of my 4C bid
with low end hand (lack of controls, not very good shape, etc), 5c
to sign off
not certain slam, bid 4nt to wait for pd's decision
I am not expert player, don't have very clear boundary for high

posts...
4C is good for the described hand, 5C is a little low in my way,
if llyshc is bidding 4S, I will reach 6C with original hand
the process may be 4nt 5c 6c... I left a chance for my partner
to talk about grand slam possibility.
however, I think there is nothing to blame 4C, and pass 3S is
completely wild... out of my logic to 2 over 1 system... |

发帖数: 21367 | 25 if in your system your 3S includes the hand you have,
your partner could not pass with all these, he/she should bid 4c
and let you decide whether 4S or not
however, usually 1S 3S is a limited raise which could be passed
hence your 3S may be a bid underbid
this slam is not easy to bid after 3S even you play it as GF.
you could start with J2NT or 2/1 GF... then the slam is reachable |

For standard method, it's just impossible to bid 6D unless one side takes

For my own system, I have a way to find it.
2C 2D(gf waiting)
2H(4 or more H , may hold longer minor) 3C(minimum, 3 hearts)
3H(longer D, 4 hearts) 3S(cuebid, agreeing D as trumps)
4C(cuebid, extra value) 4D(waiting)

I feel it's good to use splinter when you are the responder. let the guy
who has more HCPs to take the caption role. when you have many hcps, you
probably want to avoid splinter and save some bidding space.
I and my partner have encountered this scenario a couple of times:
the one with more HCP bids splinter, but the other one fails to see a slam,
therefore bids to game only. It's hard to continue slam try after that. |

1nt, you will start eith 2d, transfer to 2h.
then bid c after pd's bid.
One more round rebid c will help.
You can pretty much imagine your bidding like
2d, 2c, 4c, 4s....
After that, you will need to think about the information you got from your
pd.
It is like
2d: I have a H suite
3c: I have inviting+ strength plus a c suite.
4c: I have slam interests, plus C AK.
4S. I have SK and won't be satisfied with slam. |

发帖数: 623 | 32 I'd say, with x Kxxx AJxx xxxx, I'd bid 2D and one pd pushes with 2H, I'd
bid 3S splinter as well. Because once partner pushes, as far as I'm
concerned, it's game forcing. For such a hand, slam is not good on trump
lead (after the splinter, it's pretty marked). From partner's point of view,
I'd say this is about the limit that he can imagine. So unless you push to
slam all by yourself after 2H, you have a good chance to miss it.

can have alternative routes to get to slam (or avoid slam) but this

For instance if you have a hand like xx AKQxxxx Ax Ax, being able to bid 5H
somehow to ask S control will simplify a lot of things. If you try to cuebid
after transfer, pd sometimes may not be able to evaluate his hand to decide
whether to cooperate or not.
In addition, it seems to me that here you can have two ways t |

2C: staymen

after opener responds 5S, responder knows he has SKQ, HA, CK. 6C confirms
all keycards and asks further help in C for grandslam (he already knows
opener has CK, so no need to ask further). After 6C, opener should bid 6S

doesn't need cuebid at this moment, just 4NT rkc is sufficient. If you want
to be scientific about it, you can use 3NT by responder as artificial bid

and natural bidding space for gameforcing hands. This kind of old day
conventions are simply against the common bridge logic, "Game and slam
