所以 E(yi)=b0+b1xi=ybar+sigma(xi-xbar)^2*yi/Sxx
提取其中含有 yi的系数就是hii=1/n+(xi-xbar)^2/Sxx |

double 2C. on a weak day, I might pass 2C, but I still would balance.
I bid 4H. once a long while, pd may raise me to 5H when he holds something
like this:
Sxx Hxxx DAKTxxxx Cx
anyway, 4H costs nothing. it also suggests a good lead.
sometimes, pd may hold Sxx Hxx DAQTxxxx Cxx, against 4S, I do wish
he could find H lead.
DA Dx seems good, pd should have some cards in H, so just follow his
suggestions to draw trumps.

because you would be able to bid 4H when partner holds something like

you take 2 spades, 4 hearts, 1D, CK and two possible ruffs.
if you bid 1NT, partner would usually pass. which might not play well.

东开叫1S,
我拿了ST7 H973 DAKT743 CK5
你会争叫2D还是pass.
也许多数牌手这里会Pass, 但是我依然
选择了2D,道理是这样的,这个D套是相当好的六张
套,这样受到惩罚的可能性并不是特别大,而2D占据了
对方的1NT和2C两个叫品。应叫人拿相当多的持牌
类型都会有叫牌困难,比如Sxx HAxx Dxxxx CKJxx,
这个牌2H之后很难办。或者Sxx HAxx Dxx CKJxxxx, 这也很
难办。如果你不对对手在早期施加压力,他们的日子会
好过得多。另外,一个好处是同伴不会有多少平衡得压力。
尽管如此,我心里也不是那么坦然,毕竟,偶尔会承担-800
的罚分。西家跳了3S, 并给出混合加叫的提示,也就是大约7-9
点,四张黑桃支持,同伴pass, 东家很快就叫到了4S.
我的首攻很明确,DA, 明手的牌是:
SQ943 HK62 DQJ CT843
同伴跟出D6, 庄家跟D8。
同伴的D6有可能出自D69或者D652,无论如何,我继续拔DK,
同伴跟出D5, 显示D652三张,而D5这里是花色选择,即欢迎
H换攻,而不欢迎C换攻。下 |

忍让也是好的,情况2)庄家一般不敢继续调将,你的防守压力自然解除。
中国队庄则军忍让HA,庄家DAK后将吃D,然后送H给A,这时已是明牌。Russia牌手则犯
了不该犯的错,既没有读清S7,又没有忍让H,HA后CA,C2,送成。

发信站: BBS 未名空间站 (Sun Jun 6 22:52:56 2010, 美东)
抵达南非约翰内斯堡后,世界杯的神秘之师朝鲜队就开始了最后阶段的备战。在小组
赛阶段,他们被分在了G组,同巴西、葡萄牙、科特迪瓦同组,而这个小组也被称为是世
界杯名副其实的“死亡之组”。不过朝鲜队似乎对于这种态势毫不介意反而是信心满满
,球队主力前锋郑大世就在前不久公开发话:“朝鲜与巴西将携手出线,而我在世界杯
小组赛中将场均攻进至少一个球。”
郑大世的“狂话”恐怕会让不少人吃惊,即使在与希腊的热身赛中包办两球,估计
也没有多少人看好这位J联赛的朝鲜射手能在面对巴西、葡萄牙这样的强队时进球。然而
比起朝鲜足协副主席孙光浩的“豪言”来说,郑前锋的话显然还是太谦虚了。
在接受442杂志的采访时,孙光浩雄心勃勃的喊出了朝鲜队本届世界杯的终极目标:
“朝鲜队将会夺得世界杯冠军!”到目前为止,这恐怕是本届世界杯上最让人惊叹的争

I'd bid 4H with Sxx HQJxx DAQJxxx CAJ
I would bid 5D with your hand to show double fit and a maximum passed hand.

show dia fit and good H suit. |

3H 3NT
SJxx HQJxx DAKxx CKx
Sxx HAKx Dxx CATxxxx
1D 2H

3H shows value in H. responder has small doubleton in S, so he signs off.
SJxx HQJxx DAKxx CKx
Sx HAKx Dxxx CATxxxx
1D 2H
2S 2N
3H 4S

g**********y 发帖数: 14569 | 32 You sit south with
Sxx Hxxx DKJx CKQxxx
You heard partner open 2NT (21-23), would you explore slam with this hand? I
think the only possibility is 6C, but how to explore? |
|
g**********y 发帖数: 14569 | 33 West open 4S, North double (punishment), East pass, South:
Sxx HAKQxx DKQxx Cxx
What to do?
A. pass
B. 5H
C. 5D
D. Redouble ,IF HE CAN :-)
===============================================
This is obviously an abnormal hand. Pard has points enough to double 4S, with
14 good points in hand, I believe South should do something.
Question: should South try 5H or 5D?
Thanks for help! |
|
c****u 发帖数: 3277 | 34 it depends. when you have a running long suit and good controls,
you usually need less than 25 HCP to make 3NT.
one extreme case is that:
SAxx HAK Dxxxx Cxxxx
Sxx Hxx Dxxx CAKxxxx
you have only 18 HCP, but 3NT has very good play. |
|
c****u 发帖数: 3277 | 35 you play blackwood? if so, your partner should bid 6D over 5H.
4H wasn't a bad call though.
you have shown a very strong hand, so he should bid 6D.
I don't really think you should bid 4NT over 4D, because your pd may not
have good hearts sometimes:
Sxx HQxxx DAQxx CKQx would also justify his 4D bid in which can you don't
have a good play in 6D.
anyway, 4D here shouldn't be invitational because 2S is game forcing.
4D is an unnecesary jump which should show slam interest. |
|
c****u 发帖数: 3277 | 36 The problem is that you may open 1 level with many strong hands:
SQxxx Hx DAKQJ CAKQx, 1D is the only opening that makes sense.
1D 1H
2S 2N
3N: 3NT is wrong sided when pd has Sx HAxxx Dxxx Cxxxx
or 6C can be cold here when 3NT has no play when pd has Sx HAxxx Dxxx Cxxxxx
SAKxx Hx DAJxxx CAKQ
similiar,
2C could be bad because you have no way how to show this 3.5 suiter hand
after 2C opening.
1D 1H
2S 2NT
3NT ?
6C can be cold against: Sxx HAxxx Dxxxxx Cxx, but should partner pull 3NT
to 4D?
So I |
|
c****u 发帖数: 3277 | 37 the idea is that it allows you to show both weak hands with a long suit
or good hands with long suit. so with Sxx HAxx Dxx CAQJTxx,
you don't have to worry what to bid over opp's double over your partner's
1S opening,
you can just bid 1NT, then later raise partner's 2C to 3C.
Without this convention, you have to guess what to bid, since you
play weak jumpshift, you can't bid 2C as well, so you have to redouble,
which might not work well here.
The major draw back of the precision 1NT is that it g |
|
c****u 发帖数: 3277 | 38 because 2D may suck big time when 2H is cold
SAJxx HAKx Dxxxxx Cx
vs:
Sxx HQJxxx DKx Cxxxx
1D 1H
1S 2D
?
You may argue that you don't bid 2D with 2 diamonds,
then you would miss cold 4H here:
SAKxx HAQx Dxxxxx Cx
vs:
SQxx HKJxxx DAx Cxxx,
1D 1H
1S ?
you have no reasonable bid here other than 2D.
Even if you bid 1NT without C stopper, partner wouldn't
save you because 2H over 1NT shows a good hand.
it could be easily this way:
1D 1H
2H 3H
4H |
|
c****u 发帖数: 3277 | 39 I bid 4H. 3H would be misleading and too chicken.
This 2H denies a dead minimum,
4H can have a very good play facing such a minimum:
Axxxxx AKxx Dx Cxx and I don't think your partner should bid 4H over
your 3H here. 3H basically shows something that's weaker than a negative
double: Sxx HQJxx DJxxx CKxx would be enough. |
|
c****u 发帖数: 3277 | 40 facing Sxx HAKQJx Dx CKJTxx, you really can't make 6C, even 5C is
after a spade lead. So I don't really think 6C is a clearcut,
but still, 6C does make facing many possible distributions
and those who bid 6C are not to blame. |

c****n 发帖数: 21367 | 41 说良心话,看了完整的一节20副牌,女队两边的表现可以说惨不忍睹,
争先恐后比差。开室我们还平平淡淡,稳稳当当的做掉敌人。闭室就
完全是你差我更差,你庄做烂不要紧,我给你送回去。
印尼人太差,和我们没关系,女队闭室王萍的叫牌问题非常突出。和
上一届的章风格很相似。个人评价不是气势,是猛冒。
那一节我们一共输三副,一副 1imp的就是本来好好的4s+1,王萍在
同伴1s应叫自己1h开叫后,6张h跳叫4h抢庄。他们打精确,1s也没有提示。
最后4h mk。一副是华山一条路的4s,敌人首攻送成,然后她把暗手桥
自己打断,导致CA不能兑现-1,非常业余的错误,输了7imp。另外还有
一个赢大分的小满贯是冒叫,Sxx对着AKTx,需要取到3墩。还有一个冒叫
阻击5阶,如果敌人加倍,将铁-5,而敌人4阶都很困难,最后敌人叫到5阶
救了我们。
另外,她在一副冒叫3nt敌人做了最差首攻的时候对首攻方说"thank you"。
这样的表现不要说打美国女队,就连打很多业余的女选手,恐怕都有点
危险。当然他们可能体系缜密程度较高,但是对牌的判断,对桥牌的认识,
实在是不敢恭维。
按道理桥牌是脑力运动,男女比较 |
