With xxxx AQx KQxxx x and x Kxxx AJxxx xxx
we don't even have half of the deck, It's too hard to believe the auction
will die on 2D.
My argument was not rely on opponent's balancing. 2D works because I don't
expect we have a magic fit, if we do have, partner must have extra to bid on.

I'd say, with x Kxxx AJxx xxxx, I'd bid 2D and one pd pushes with 2H, I'd
bid 3S splinter as well. Because once partner pushes, as far as I'm
concerned, it's game forcing. For such a hand, slam is not good on trump
lead (after the splinter, it's pretty marked). From partner's point of view,
I'd say this is about the limit that he can imagine. So unless you push to
slam all by yourself after 2H, you have a good chance to miss it.
It maybe the same 11point in D contract, but the actual hand, with

劳动节打了个Regional Swiss,还挺好玩的.贴出来给大家看看.挺多故事.倒不是牌局如
何精彩.
报名的时候,我们和另一个朋友一块去买entry,结果拿到的队号是相邻的,这就是说,我
们第一轮就自相残杀,这不好,于是我们去换.换到的对号是1号.
第一场自然对2号队,我一个人也不认识.看上去就是不大会玩牌的,我一直心里有个疑问
.这天的瑞士移位赛有A和B两组,不会说换了个队号,把我们错误地换到了B级?很想问问
对方这件事,但是这个似乎有点insulting.只好作罢.
第一副我持Qxx x Axxx AT76x,右家开2D,两家不叫后,同伴加倍,我3C,lebensohl,表示
邀叫,买到了定约.同伴摊下KJT9x Kxxx x Q9x点力差了点儿,可是3C是天堂,交叉将吃后
,拿到10墩牌.
队友这副没有阻击,于是2H买到,也做成.双得赢6点.
第二副我们打宕了敌人2S,不是很困难的防守.
第三副,假定你拿AK73 xxx xxx KJx,防守3NT,敌人叫牌是1D(右家,明手)-2NT(邀)-3NT.
同伴攻黑心5,明手摊下QT AKTx QJ98x xx,你黑心K赢了第一墩

来自主题: Bridge版 - 这牌怎么叫?
As I said, 3H is overbid, but 2H is underbid. 2H is more of an underbid than
3H as being overbid. Give partner total minimum hand like x / Axxx / Axxx /
Kxxx, 4H is favorite, but partner won't make a move over 2H. The key point
is that partner is supposed to be short in spades, and you have xxx there,
no wastage. You also have nice hearts (especially 5th H), CQ is probably
very useful too. All these make this hand closer to 3H than to 2H. I don't
know whether I will bid 2H or 3H at the table, bu

二楼的基本想法是正确的,这牌的主要机会在于右手持DK,左手持DJ,要通过投入加挤
牌完成定约。但是二楼的打法需要右手一定是4333牌型,而我仔细分析了一下,还有别
的牌型也应该可以兼顾。把打牌顺序调整一下:先打三轮大将牌,红心AK,然后打梅花
,将吃CQ,再将吃红心回手,送出小将牌,投入东家的同时挤住西家。按照这个顺序,
东家除了4333以外,即使是持牌如下,一样可以做成。

来自主题: Bridge版 - 跳闸
这里4S是不该受指责的。2S是限制性的,不会是15~17HCP的均型(开叫1NT),或14+HCP
的非均型,如:
S Axxx
H x
D KQxx
C KQxx
就应该考虑跳3S了(4S要求是SKxxxx加一个A,而这种牌同伴通常是不会在2S后再行动的
)。所以2S以后再叫也不会是14+HCP的非均型。
4S受2S限制,也与X, XX, 3H相关,通常同伴XX有4+H,S一定是5+,(如果同伴H<4,则
敌方H>10),这个4S对同伴的要求是S5,除H外7~8HCP。如果拿:
S Axxx
H
D KQxxx
C Kxxx
则应该扣4H,2S后4S已经显弱。
至于1D开叫主要不好的是低花倒54,而5D-6S是有这种表示1A+缺门的。

我来试试 (没有做完):
先数赢墩:6s,1h,1d,1c。C还可以发展1墩。明手可以将1墩。第12墩要么飞中CK,
要么明手多将1墩,要么h长套发展1墩。明手进手最多4张(3s,1c)。
手上将拿第1墩,先拔hA,然后出c6;
1)如果西家赢(本来飞不中)。如果西家再出s,还有时间可以发展h长套。只要h不是
Kxxx,总能发展2墩出来(将牌作桥两次将吃出K:K/Kx/Kxx,d回手清将,c回明手,h
好了)。如果西家不再出s,有时间明手将2墩d (明手先垫1d在大c上)。
2)如果东家赢(本来飞中)。东家没有s出,有时间明手将2墩d 。
3)如果东西忍让,庄家好像还是没办法?(K 西家)

来自主题: Bridge版 - 讨论下这个坐庄
探讨一下这个单套结构的防守
明手Txx,你做庄家的右边,
如果手上AQx,打Q是表明的防御,几乎不会有损失(除了庄家单K),可是给庄家造成
了猜断。
现在的问题是,如果你坐在庄家的左边,手上持有
(1)Kxxx,AJxx
(2)Jxxx
(3)Axxx
看到同伴的Q庄家放小,这时候要怎么给信号。
情况1,毫无疑问,强烈欢迎。
情况3,同伴多半是QJx之类的引出来的,根据情况给出不欢迎或者中性的信号比较合理。
情况2,事情有些好玩,你知道同伴做了一个虚假的引牌(缺省Q承诺J),你需要帮助
同伴欺骗庄家,一个中性的信号可能是最合理的。
稍微做些引申,如果明手的花色是xxx,同伴引出Q,庄家放小,你手上有Jxx这种,这时候要根据情况来决定是应该解封(同伴从KQT9中作出的引牌)或者配合同伴的欺骗。好在此时防守方有优势,几乎不会在单套打法上猜断错误。
再稍微引申下,论点对错不做保证;-)
坐庄的优势更多的在于对全局的把握,具体到单套牌处理,防守方其实更有优势。防守方最难得是换攻,找到庄家的弱点。
所以针对这点,好的庄家都要在早期防守方对全局不甚清晰的时候逼迫防家作出转攻或者垫牌,不要让防家有足

来自主题: Bridge版 - 争叫后的扣叫如何理解
顺便提一下,对手的叫牌也很弱。既然要加叫3H,直接在2H扣叫之后就应该出来了,这
样才能剥夺对方空间。有时候对方叫牌不合理,也会导致己方错判(不是指这副牌)。
前几天有个朋友问我,拿着 AQxx, xx, Kxxx, Jxx,双无,右手1H,左手2H,PASS过来
,是不是可以平衡加倍。我说可以,但问他这是什么比赛,答曰 bracketed swiss, 据
说对方第一次打 swiss,我说那你还是看看临场的 table feeling 吧。实战中他加倍

来自主题: Bridge版 - Spingold 防守讨论
庄家像是2-4-3-4牌型。同伴即使H或D上有大牌也会被飞死,所以只能寄希望他有一张C
大牌。
但如果我们自己主动进攻C,庄家是KXXX的话就把定约送成了。
我觉得还是应该保守攻牌,庄家D能吃通的话也只能垫两张C,最后还是得自己动梅花。

显示额外实力,竞争性,理论上黑桃张数不多。东家的4NT暗示双套,从后面的叫牌
来看是方块/红心套。

来自主题: Bridge版 - 谁的错误多一些?
你还是没有说什么赛制。MP不一定要叫得很激进,毕竟联手最多24点,叫到一个庸俗
的定约之后还有其他机会得到好分(比方多做超墩)。叫了3H之后如果同伴回到4D,定
约不一定安全。比方同伴的牌也许是:Jx, Qxx, Axxx, Kxxx
这个牌我说3D叫得不好,也正是因为容易误导同伴,认为南家的点力相对集中在低花上
。而SQ/HQJ对于无将来说很有用,打花色定约则可能是浪费。

I don't buy this concept at all.
If you hold a good and long D suit and around 14-15 HCP, you simply can't
make a takeout double first then bid your D suit. So you can only bid 2D
first and try to double the next round. For example:
- Axx AKJxxx Kxxx, the only possible sequence here is 2D then later double
2S as a take out.
Also, it's a nonsense to forbid the double with a void in this situation.

But if RHO holds short C, even if it's a stiff CK, you are always safe if
you play CQ on first trick. The benefit of that is when you actually find
out RHO has Kxxx of C, you can still rely on D finesse to make the contract
-- even though in this case, it is more likely the S is 4-4. While low C on
first trick and low D to K deprives you this chance.

This is simply the wrong bidding philosophy. Bridge is a partnership game.
What 4S achieves is just that I think I have an offensive oriented hand, if
they can make 4H, our 4S shouldn't be too expensive. It doesn't show your
shape, which can be very important for partner to get involved at high
levels. 4D shows a respectable hand, so partner can double their 5H with
suitable hands and 4S can be bid based on 7 spades, only 11 HCPs, like

He had something like Jx T9xxx Kxxx Jx. The point here is that 4S doesn't
show much of a hand, so it's relatively easy to bid 5H over 4S, which is
very difficult to get penalized, especially for somebody like the Italian
guys, who don't have a crazy bidder image. Also when white vs. red, opps
often like to take some insurance to bid 5S back.

输张应该是5个,同伴叫过花色上的Q,肯定算成赢张。
理由很简单,如果你联手有Kxxx对Qxxx,那么K和Q对你
来说是等值的。
但是我还是叫3S,输张计算只是理想情况,要求同伴要持
合适的大牌。拿这个牌,即使同伴4S接受邀请,也很有可能
一门花色各输一墩。
更重要的是,4D不仅仅表示你要打4S,而且有鼓励同伴继续
叫牌的意思,对吧?这手牌虽然有很好的赢墩潜力,但是
控制差了一些。
这里4D,通常需要有两个以上的第一轮控制。站在同伴的角度
想一想,在1H-1S-4D之后,他有可能拿着还不错的10点牌,愿意

是的,打CQ更好。
现在可以简单计算一下概率了。先动梅花的话:

1)梅花3-3且梅花大牌分家:大约18%
2)左手梅花J或Jx:大约6%
4)左手Kx,Kxxx,或Jxxx,此时需要红心飞中:大约9%
合起来大概58%,不如飞红心机会大,更严重的是脑细胞远远透支。。。

我也来乱弹一下: 2C逼叫一轮, 2H之后手里不在3阶争D很正常吧, 套差了点, 等待
同伴描述一下挺好 (如果加倍,表示高限估计更精确?)
同伴自由争出3D之后, 我觉得就需要比较仔细的思考(再叫3H之前)
1. 这个牌成局是必然的, 3NT还是5D呢, 需要试探
2. 这个牌甚至有低花的满贯, 如何兼顾这个机会比较重要
我自己的看法是,如果同伴拿下限,但是点力牌型都不错, 你能很顺利的摆出满贯的
牌(不依靠防守方的牌型极端分布), 就需要保留试探满贯的余地
但是实战叫到这样,我设计不出合理的叫到6D的牌。 估计4C之后摸一个5D完事。(方
块套配合没有显示, 你要求同伴红桃单张; 红桃Kx都不好,首攻就穿一下

我也来乱弹一下: 2C逼叫一轮, 2H之后手里不在3阶争D很正常吧, 套差了点, 等待
同伴描述一下挺好 (如果加倍,表示高限估计更精确?)
同伴自由争出3D之后, 我觉得就需要比较仔细的思考(再叫3H之前)
1. 这个牌成局是必然的, 3NT还是5D呢, 需要试探
2. 这个牌甚至有低花的满贯, 如何兼顾这个机会比较重要
我自己的看法是,如果同伴拿下限,但是点力牌型都不错, 你能很顺利的摆出满贯的
牌(不依靠防守方的牌型极端分布), 就需要保留试探满贯的余地
但是实战叫到这样,我设计不出合理的叫到6D的牌。 估计4C之后摸一个5D完事。(方
块套配合没有显示, 你要求同伴红桃单张; 红桃Kx都不好,首攻就穿一下
了; 当然同伴有K, 就停在3nt了)
(如果需要拼搏的情况,或者需要赌把运气, 拉到6D也不是完全没有可能; 假设同
伴的牌有方块Kxxx, 红桃Kxxxxx
再加四个点,3张牌,6D还是有不少机会的。)
同伴3H之后4C有点问题, 没有需要的第6张草花 ;但是没有叫到5D,是你的问题

能叫2S的前提是这是逼叫的。当然,玩SAYC, BWS的专家们这里很少有人会当成逼叫一
轮。
如果2S逼叫一轮,这个套没有任何问题,因为2S不承诺好套。
如果你总是打算搞到至少4阶甚至五阶,那么2S当然不是冒叫。来个更极端点的例子,
AQxxx x xxxxx xx, 这个牌如果2S逼叫一轮,那么叫2S也没有大问题(虽然3S如果是
fit showing jump的话会很理想)。原因很简单,面对同伴
Kxxx xx AKxxx xx之类的牌,你方至少要叫到4S,然后5S也不是不可以叫。
S是H的天敌,如果有一个机会能在2阶叫出来,而不叫出来,后面你总是难免会后悔的。
类似的,在拿了SAKxxxx Hx Dxxx Cxxx的时候,如果听到右手开叫2H, 2S也几乎是自动
的,
除非在有对无的时候不那么明显。
还有就是AJxx x AKJxxx xx, 这种牌在1H后面来1S也没有太大问题,当然后续需要有手
段来澄清这类持牌类型。

Why? Because combined chances for line 2 + line 3 is better than line 1?
As I mentioned, you cannot add those together. Starting with J may not be
immediately fatal, but you have to guess on next round, and you have to
calculate the percentage that you will guess wrong, then derive the success
rate of either line 2 or 3, but not both, then compare that with line 1.
To give you an example, which looks different but actually the same. Say you
are in a slam, you cannot lose another trick. Suit 1 is... 阅读全帖

lc9基本是9mm里面最薄的了,好像还有一个kxxx什么的比它薄,不过价格比它贵多了。

It is very unlikely he had a wrap on that flop. There are 6 blockers already
, no player would get crazy with wrap with paired board. I'd expect AAxx
fold on the turn blank (假设 turn 7) since this was in a PLO tournament, it
is pretty clear you at least had a K.
IMO, the calling range on the turn is very narrow, KTxx, Kxxx with a very
strong kicker like AKxx. Or the turn blank made his K7xx to a smaller full
house. He might have AK7x with the redraw. The worst case, he was
freerolling the river w... 阅读全帖
