这手牌在同伴显示黒桃后应该算2NT中的最好牌，可以拉出来叫4NT。

发帖数: 524 | 3 My point was, you may want to ask this question
*BEFORE* rushing into 4NT.
A slam requires at least "2 A + Q", but suppose that is the case,
what else could he have?
Therefore, this slam can't be a sane one. |

发帖数: 642 | 4 This looks like a psychological guess. When LHO chooses to cue a major, he
should cue one with control (may be 2nd round control). But I saw some top
players cue the one without control, and I have no idea why they do it that
way.
RHO's 4NT may suggest control in spade, but maybe he has 3 or 4 spades, so
he can deduce his pd holds singleton or void spade.
So there is no clear answer based on above nonsense analysis.
The most reliable player on the table is your pd, so we should always trust
him ... 阅读全帖 |

发帖数: 2804 | 5 Actually, I think N-S just misbid, instead of intentionally gamble. There is
no reason for them to feel that they have to swing. This is not barometer
game, they had no idea that they were behind by 4 imps. They could easily
lead by 4 imps instead, and only need to push the board. It is possible that
they had misunderstanding over the 5NT bid.
I don't think 4S is a clear overbid. South did have extra value, if 3C only
showed limit+ hand. He didn't know north had void in diamonds. From his

发帖数: 2804 | 6 Since 3C cuebid is not game-forcing, West's 4C bid creates annoying problems
. It deprives an entire level of bidding from N-S. Even experts cannot agree
what should 4D from North show. Does it show slam interest, or a secondary
suit (so that partner knows what to do if opponents bid higher), or maybe it
is "last train" (which doesn't even promise diamond control)? We don't know
N-S agreement here, so we are all just speculating here.
But I think South does have enough to bid beyond 4H. Even if ... 阅读全帖 |

发帖数: 2804 | 7 If 3NT is "non-serious", then 4C is "serious cuebid". I think I'd bid 4NT
now. |

发帖数: 2804 | 8 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. |

发帖数: 2804 | 11 其实在有对无的局况下，我觉得西家的3H叫得还是不错的。在这种局况下，叫4H经常是
使对方没有选择只能加倍，而西家牌型较为平均，4HX未必是个好的牺牲。3H剥夺了对
方较大的空间，已为其信息交流制造了足够的障碍。
作为南家，首先4NT是个糟糕的叫品，无法判断同伴的关键张是否长在红心上面。鉴于
叫牌空间的问题，要把牌完全叫清楚已经不太可能，我会考虑直接叫5NT，让同伴在梅
花和黑桃中选。我想这个叫品基本上应该暗示五张黑桃及四张梅花。5H也是一个可选的
叫品，但可能会被当成对于黑桃的排除性关键张问叫，容易产生歧义。 |

发帖数: 2804 | 15 3H是合理的。假设你叫3H，同伴接着叫了4C。听着像是扣叫，虽然不排除黑桃/梅花两
色套的可能性。你继续叫4D，不管同伴是哪种牌，4D都不会太错。同伴现在4NT，这个
可以印证前面的4C是同意红心为将牌的扣叫。你答叫5NT，表示两个关键张外带一缺门

发帖数: 2804 | 16 If you had a hand that you intended to invite in hearts (plan to bid 1S then
3H), you can bid 4H after 3D. This is a value-showing bid.
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.
1H-1S-3D, you have:
3S = natural, often 6+ or 5 good ones
3NT = soft value on S and C
4C = cuebid for diamonds
4D = diamond raise but not suitable for 4C cuebid

holding, rather than keeps asking.

发帖数: 2804 | 27 对方点力范围并不清楚，但有一条线索是，左手家叫了4C。如果右手是0355，那么左手
方的牌型就是2155，可能持DA的话更倾向于选择4D而不是4C（如果我拿着这个牌型，无
对有，会考虑直接4NT加深阻击，不过这个是题外话了）。总体来说，右手方持DA的机
会较大。
你明明不止会飞牌，挤牌也在行啊。打得不错赞一个。
实战庄家从明手出一张小方块，其实也是一条思路，但需要右手只有DA没有DQ，而且还
不一定会打错。挤牌的打法，基本上只需要右手持DA即可（加上左手单张HK作为先决条
件）。 |

发帖数: 1295 | 35 agree with the strategy.
For MP, 4S should be ave+.
For IMP, the difficulty is that both hands are not limited from PD's point
of view. So cue bid seems mandatory. Possible sequence could be 4C-4D-4H-4NT
.... I tend to accept 6S if key card is ok. However, it may not be a good
slam (50%). |
