那很容易呀
b1=sigma(xi-xbar)*yi/Sxx
b0=ybar-b1*xbar
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

I bid 4H. once a long while, pd may raise me to 5H when he holds something
like this:

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.

suppose you have such a hand:

over 1C opening, still double works fine,
because you would be able to bid 4H when partner holds something like
this:
Sxx HAQxx Dxxx Cxxxx
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.

第二副,南北有局。
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:

Some players at the bidding stage did something strange. If west didn't pass

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

it depends. when you have a running long suit and good controls,

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.

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.

看不出最佳的路线,我的选择比较简单,SA兑现,不出意外肯定是2-2分布(要是3-1就
SQ要H回攻),然后兑现HA,继续S,希望同伴持有Jxx/Qx以上。
这么打如果庄家持有坚固的C同时没有大牌的时候就愚昧了,不过从这个4C的叫牌感觉
不像类似Sxx Hxx Dx CAKQJxxxx这种(如果7张C可能不会选择4C阻击,如果8张C或许会
