promising young man, congratulations!
but be sure count your cards next time :-)
Yet you should have slightly regreted your bidding,
shouldn't you?
no way to beat 3NT if south is the declarer.
You don't know if you can make 3NT, but you know it is
almost always
better to make your pd declarer with that hand? don't you?
How?
1C-1S-3C-3NT might be a reasonable sequence. or a tricky one
1C-1S-2D-3D-3H-3NT..... |

叫牌很简单: 1C-1D-2NT-3NT （对方没有插叫）
6D乃至6NT貌似不是一个很差的定约，不过你现在要集中精力做成3NT。西家首攻S5（长

发帖数: 985 | 6 这副牌5C打不成，

不过这样的牌型，
该怎么叫到3NT呢？ |
|
w**n
发帖数: 244 | 7 3NT 的叫牌本来就是带赌博性很强的叫牌, 有一坚强低花
套, 加上在一高花有止就可以赌了. 想想赚了可就发了.
如果两门有止, 再加上一坚强低花太强了反而不适合开3NT
吧, 和牌手也有关叭. |
|
c****u
发帖数: 3277 | 8 3C might not be a good bid here cause your C is just too weak, and
you can hardly belong to 5C. 3nt is
actually a practical choice. of course after 3nt, south can bid 4S
cause his diamond is rather weak. For the play part, silicon's line
is right I think. |
|
m****r
发帖数: 6639 | 9 这个是imp的记分. 也许找c fit有一定的用途.
如果是mp记分, 我觉得5c 比 3nt 或者 4s 好的情况太少太少了. 而且南的点力放在
那里, 还有两个A, 3nt再怎么也不会错的. |
|
i****e
发帖数: 642 | 10 Yes, there are too many uncertainties. One important clue may be declarer's
choice of 3NT instead of 4H. With ATx KQ9 xxx AKxx, we can't say it is wrong
to play 3NT, but I would choose 4H.

发帖数: 43 | 20 我如果拿到这手牌， 很可能也叫3nt.。这有赌的性质，依牌手风格而定。
不知道首攻方的牌型 牌力。如果低花套不是很强，我认为应该赌高花，以高花
首攻，因为是无将定约，似乎你低花套较强的可能较大。 |

发帖数: 667 | 21 除非是七张套，并且至少其他两门有止，我才会试3NT

|
c****u
发帖数: 3277 | 22 那你干脆每把都开6NT, 反正1000副里总有可能蒙上1,2副.
赌博性3NT的最大问题是庄位可能不对. 而有边花实力的话, 1阶开叫往往
更合适些.
对方阻击又如何? 叫牌本来就是会泄露一定信息, 但其收益是找到相对合适
的定约. 我不赞成超级科学的暴露狂式的叫牌, 但这是两回事.
说到底是看概率, 看长期下去哪种方法的收益最高. |

Against Strong opps, I open 1NT, opps remain silence,
pd transfers to hearts and rebids 3NT, which is the
final contract.
West started with the Dimond Q, on which I covered with
Ace and East followed the suit with 4. Since I 'd like
to gather some distribution information first, I played
off 4 round spades. It turned out that east had 98 doubleton
and dicarded club 2 and heart 3, in that order. Not much help
so far.

发帖数: 3277 | 25 On the second day of spingold, you were 56 imps behind a strong
team including famous bobby wolff and kit woosey with 16 more boards to
play. They missed a slam and went down in a couple of hands, so you
feel you may have some chances.
Now you found this holding in the 7th hand:
SA HKxxx DKTxx CT8xx
so you passed at the second seat,
and partner opened 1C at the fourth seat:
p p p 1C
1D x 1S 2C

since you are behind and you hold pretty good club support,
you really don't need much to make 3nt, |

南3NT。 西首攻S4， 明手放S10，东SJ， 庄SQ拿住。
如果红桃3－2， 很简单。
如果不是， 红桃该怎么打？
实战中， 因为我不想让东穿我的黑桃和草花， 所以我先从手里打小红桃
如果西扑大牌， 明手放过。结果西出H2， 明手该HA， 东跟H3。 再打红心，
东盖H10， 我盖HK， 西家贴了一张黑桃。
往下怎么打？ |

发帖数: 20570 | 37 actually north's 3NT is rather a bad bid. North should bid 2NT here, then
south can bid 3H to show 6 hearts, but suitable for defense. Now north can
raise 3H to 4H. |
|
p***r
发帖数: 20570 | 38 This treatment is rather bad. So with a true penalty double hand, responder
would double and opener may pull with doubletons. That would allow your opp
to escape from many huge penalties.
As I said, the best treatment here is to play double as a transfer to NT,
which can be passed by 4 spades. Pass to show a penalty double hand.
Also, your worry is not necessary. If you play direct double as a penalty,
responder can bid 2NT with many balanced hands without a stopper after
opener passes, since 2N... 阅读全帖 |

p***r
发帖数: 20570 | 39 Actually trying to penalize opp at two level with 3-3 split can sometimes
lead to huge disasters. 3-3 is good for defense when opp is quite (semi)
balanced and you may have crossruff potentials. In this situation, 2S is
usually bid by long and good spades with shortness somewhere. So most of
their assets are in trumps, but not side suit honors. They are most likely
to take 4-5 tricks in trumps and a few side tricks. So it is quite rare that
your 3-3 trump would ruff out their side suit honors to... 阅读全帖 |
