发帖数: 623 | 1 Other day saw this and I thought it was humorous:
We all know that after oppo's 1H/S opening, a 3H/S cuebid shows a solid minor
and asks pd to bid NT with stopper. The Tasmanian cuebid is the reverse: in
the same sequence the 3H/S means: pd, I have stopper in their suit, do you by
any chance have a solid minor?? |

I am not sure which way works better, perhaps I should do some
simulations. still, responder may have a strong suit, so if we play this style,
2C - 4C should be set up trumps and ask for cuebid. also, we may have some
trouble in looking for 4-4 fit in majors since 3H/s are cuebids now.
perhaps we can play it two way, either a cuebid for C or real suit. so
if we raise D at the next round, it's a cuebid, named pre-cuebid

发帖数: 2804 | 6 It should not be a cuebid. If you have diamond fit, you should have bid 2S (
that IS a cuebid) earlier, instead of double. If you have general value but
not able to double 4H, you can bid 4NT here.
If bidding is below 3NT, you might bid 3S (as cuebid) to search for 3NT. But
here bidding is at 4-level, so I cannot think of a need for cuebid. |

Yes, you are right, anyway, bridge is just 拼体力 sometimes.
Perhaps north should have made a cuebid over 4D cuebid. Who knows.
or south should have made a cuebid over south's sign off. Also, I really
don't mind missing a slam here.
Another point I want to mention is that Kxxx Axxxx Qxx X is
worse than Kxxxx Axxx xxx x, because the 5th spade may provide
an extra trick to for pitching which might be crucial.
So a better sequence might be something like this:

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. |

发帖数: 623 | 10 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

after that, if partner can bid 3H, you'd bid 3S which is a cuebid.
if partner cuebids 3D/S which shows some sort of club support, you'd
cuebid the other unbid suit as a slam try as well. Then you'd
check key cards to decide which slam to bid. If partner bids 3NT
over 3C, you want to bid 5NT to ask partner to pick a slam. |

发帖数: 20570 | 14 The basic idea is very simple here. Liu Jing sometimes may not really need
trump Q at all, because he may hold trump Q. In that case, side suit kings
are very important. So 5NT should be reserved for that purpose to preserve
space for cuebids. Therefore, a direct 6S has to show trump Q and no side
kings. Actually, in early days, some players do play a direct jump to trump
suit to show that hand type after trump Q asking. 5NT to show trump and no
side king allows you to cuebid side queens, which ... 阅读全帖 |

Qx Axx Axxxxx xx
Here, after the 3H, players should have agreement on 3S. My suggestion is a
cuebid because your splinter is not looking for a major fit so your splinter
often shows 4 spades.
Suppose partner bids 3NT, you can either pass or bid 5D. I think both bids
are very close. If partner bids 3S as a cuebid, you can RKC.
If partner bid 4D to deny 3NT and a control in S/C, you can cuebid 5C to

The main point is, after jump-shift (which consumes space), you need a
waiting bid like 3H. It is ambiguous, but it makes other bids more defined.

3S = natural, often 6+ or 5 good ones

I guess a diamond lead works.
Pd could hardly be club void. coz that means opps have
9 clubs, i.e. LHO has 4 clubs at least. In this case,
he would have passed 5C or 6C most of the time.
It seems that RHO didn't take 4C as Ace asking, otherwise,
he should have passed 4NT. Therefore, 4S was a cuebid and he
took 4NT as Ace asking.
I guess the reason of LHO's hesitation is one Ace missing,
and he was thinking of taking chances that the missing ace was
not the crucial one.

or cooperate with a cue like 3H, or go beyond. If after you return to 3S, and
opener bids further, either 4S, or another new suit, than the original 3D's a
cuebid showing slam interest. Say after 1S-3C-3D-3S-4C, 4C gives you another
chance for cuebid and shows a strong slam interest. Compare to 1S-3C-3D-3S-4S,
that sequence shows some moderate slam interest.

发帖数: 3277 | 23 unusual vs unusual is popular.
suppose your partner opens 1H, your RHO bids 2NT,
now your double shows that you want to penalize opponents in at least
one suit. your 3C shows a good hand with hearts, at least invitational.
3D: shows good hands with spades. 3H: competitive.
3S: construcative, nonforcing.
The basic principle is that:
cuebidding opp's lower suit shows a good hand with the lower rank
unbid suit;
cuebidding opp's higher suit shows a good hand with the higher rank
unbid suit.

two suits. So you can bid 3D to start cue. This gives you opportunity to do
something before committing past 3NT. Sometimes responder bids with 5-4-2-2

SJS is not right for this hand anyway, it's a 6-4 two suiter.
obviously east's 4S is a huge underbid. The right bid is 4D over 4C as
a cuebid. When one holds only 3 losers and partner made a extra showing
bid(4C) after opened the hand, 4S is just a crime.
West's 4S is rather bad, he should bid 4H as a cuebid and partner would
cooperate for sure.
4H is bad, 4H rebids show a weaker hand here. |

high, suppose partner holds 3-5-3-2 shape, and no points, he will be
forced to bid either 3H or 3S which can cause you a big trouble because
it may get chopped. You often can't tell
whether a cuebid shows first round or second round control, usually
you just ask RKC to clearify it. However, there are some rare situations
that you can't RKC because of your voids like this one, here, you need
to apply a lot of logical thinking at cuebid |

everything is Standard), 3H is forcing. If partner bids 3NT, you can cuebid
4S to implicitly set hearts as trump (which shows 6+ hearts); if partner
raises to 4H, you can rkc; if partner bids 4m, you will have headache, but
no more than starting with ambiguous 3S.
I think in general, willy-nilly "we don't know what it means" cuebid is a
bad habit in bridge. |

发帖数: 623 | 33 I don't think 4H can possibly be HA, in fact it should deny H value.
The reason is you've skipped both C and S, if this is a cuebid of control,
how in the world can you suddenly do control cuebid with no value in either
S or C?
In addition, pd did not splinter, so he's likely to have concentration in C
and little or no value in S, if you don't have S control, you would bid 4C
and soon you will play 5D.
Typically when you do a Splinter, you guarantee values in the other suits.

After 3H, the way I play is: 3S shows non-serious interest (i.e. "I am
willing to cooperate just in case you have serious slam interest, but I don'
