发帖数: 58 | 2 一、 开叫高花经同伴加一应叫后， 该怎么计算牌力并叫牌？例如1H
（1S）—2H（2S）—？这时，开叫者应计算己手共有的打牌赢张，据
此决定进退，这比依据大牌点可靠。打牌赢张由大牌赢张与长牌赢张
两者构成。
（1） 大牌赢张算法是： 3=AKQ；2? AKJ，AQJ；2=AK，KQJ，AQ10，
AJ10；1?AQ，KQ10，KJ10；1=A，KQ，KJ，QJ10；?K×，QJ×。
（2）长牌赢张算法是：主牌套为4张套=1，5张套=2，6张套=3，.....
.。边牌套为4张套=剑?张套=1，6张套=2。
（3） 开叫者将己手牌的大牌赢张与长牌赢张相加，得出的打牌赢张
如果少于6， 便应该不叫；如是6—6套，便应再叫，试探能否成局；
如6以上，便应当叫到成局。
（译自Hugh Kelesy著instant Guide To Bridge）
二、应叫者对长套试局叫（Long Suit Trying Bid）该怎么计算牌力
并叫牌？按上述的情况，开叫者有6—6套打牌赢张，拟试探能否成局，
便可叫其较弱（通常只有一张大牌）5? 或4张套副牌，问同伴能否给

在北开叫1NT的前提下, 这里问题的关键是北需要明确地知道南有红心
5张套以及草花上的控制, 才可能顺利地配合满贯叫牌.
任何自然的叫牌在这里都将无能为力. 必须借助于一些人工的约定叫.
那么, 在开叫强无将后的叫牌结构里, 可以引入哪些表示两套牌的约定叫呢?
最常用的是SMOLEN转移叫. 通行的SMOLEN转移叫的基本结构如下
1NT - 2C -
2D - ?
2H, 2S, 所叫的是5(6)张, 表示高花5-4, 6-4的弱牌, 开叫方应该PASS
3H, 3S, 所叫的4张, 另一高花更长, 当然是进局逼叫的实力, 开叫方在
另一个高花上有3张, 通常选择高花进局, 否则叫3NT.
上述的结构有两个弱点:
1, 未能包括邀叫实力有两套高花的牌, 而这种牌的出现几率是很大的.
2. 未能阐明如何处理5-5以上高花的牌.
我们对SMOLEN转移叫的改进的处理方式即着重于上述两点.
为了强化局和满贯的叫牌手段, 我们放弃了对弱牌的精确处理.
1NT - 2C
2D - ?
1. 2H, 2S, 不再是表示5-4的弱牌, 当你持这种弱牌时, 现在只好选择转移 |

-7s.
even that 6h can be 7sp too.
btw, if u do want to add a convention , u can use 4c as void rkc.
so 4c is to ask rkc except club suit.

Pd can reasonably deduct that you have a spade suit so you do not bid 2H first

首先需要澄清的是, 在平衡位置的无将争叫的牌力. 大体上是
11-15点: 争叫1NT.
16-19点: 加倍, 以后再叫无将
20-22点: 跳争叫2NT.
那么, 面对同伴11-15点的均型牌, 持南的牌应该如何考虑呢?
普通的第一感是再加倍, 表示至少有邀叫牌力. 但请注意, 并
不是所有的有邀叫牌力的牌都应再加倍, 再加倍的主要涵义是
强调防守能力, 而不是进攻能力, 它期待联手对以后敌方的逃
叫进行惩罚.
所以需要对具体的牌情进行分析, 而不是仅仅应为有些大牌就
再加倍. 持这手单张红心的牌, 你首先应该问问自己, 红心套
哪去了?
同伴很少有可能有5张红心, 这意味着一般情况下, 敌方联手
有8-9张红心. 那么你必须要考虑如果你再加倍, 敌方逃到2H
时, 你怎么办? 如果同伴加倍2H, 你是否PASS?
也许大家都有过这样的经验, 联手4-4配买到2阶定约, 或联手
5-4配主打3阶定约, 只要坐庄正确, 无论成还是宕, 结果总是
不会差的. 为什么呢? 这是因为总墩数定律在起作用.
无论是总墩数定律的推论还是牌手的经验, 都会告诉你这样的

发帖数: 623 | 12 Non issue if playing forcing 1NT. Planning to take preference to 2H after
partner's 2C response, and raise 2D to 3D as a preempt as oppo rate to have at
least 8-card S fit. This normally does not show an invitation as you have a
stronger 2S (impossible S) rebid. If partner rebids 2H you pass. If partner
rebids 2N, you sign off 3D. If he reverses to 2S, my preference is to play
lebensohl style: 2N relay to 3C, and you bid 3D to sign off. |

If you decide to bid 2H. I have to admit its legitimacy. But maybe you
are not quite aware of what you are doing.
Given the 1NT response, most likely, you are going to play in notrump and
won't have any crazy dream of making a slam. Thus the only problem left
is whether you bid a game or not. Who are going to make the decision for you?
obviously, you should consult your partner. The most straightforward way to
do it is giving a 2NT invitation.

发帖数: 14569 | 19 From your pd's perspective, I think 2H is better, because --
In standard system, 1D-2nt shows 19-21 points, very likely 2nt would push your
pd to 3nt.
But 2H shows 17+, now it's your pd's turn. He knows you are 17+, if he respond
2nt, it's a sign that he probably doesn't has extra value. If he bid 3c, I
would take that as invitation for 3nt and go for it. If he bid 3D, I would
most likely pass.
pd's 1nt shows 6-10 points and no 4 cards in major. Given that, I think game

发帖数: 623 | 22 This structure starts to make a lot of sense. I like the query for suit
quality on the other minor and query for singleton on your own minor.
However, after 1D-2H, we need to handle the case that opener has D suit (or in
general no C tolerance) and with extra values. Since 3D is signoff, opener
will have to bid either over 3D blindly or start with a relay. Either way it
could be awkard.
Perhaps after 1C-2H, 3C could be treated as extra with good values in D --
opener can always sign off in C wit |

Another option is 2H, but 2S is better since it shows value in sp.

Also, I don't really like precision's design of 1NT to show good raise to 2M.
The best structure so far is to play 1NT to 2H as transfer to the higher suit.
So 1NT shows C suit, can be weak or strong.
2C/D, transfers to D/H.
2H: good raise to 2S.

With some partners, I play 1D 1H 2H even when I hold 4 spades and 3 hearts:
4-3-5-1 shape and around 12-13 HCP. So partner's 3S doesn't garantee 4 hearts.
For standard treatment, people usually bid 1S over 1H with 4 spades and 3
hearts. So you still can move on. you need partner to hold

you use 2/1, so you go with 1NT.
Obviously, if P bid 2H, you will be very happy to bid 4H.
Now, if your P bid 2c/2d what is your guys opion?
2H?
Or if your P bid 2s, will you bid 3H, or pass? |

同伴开叫1H，你如何应叫？
××××××
同伴(north)抓了

叫牌过程：
1H 1S 2H 4H 5C 5H -
问题：
1. 有什么更好的叫牌过程？
2. 假如南家在2H之后选择叫3H，是否逼叫？
3. 假如北家在1S之后选择叫4H，是否会被认为是黑心支持？ |

发帖数: 472 | 47 对， 我叫错了
我开始以为你2H转移， 叫了2S
后来你叫3NT， 我觉得你的2H实叫， 就pass了 |

发帖数: 32 | 48 你的问题是, 你没有想到没有必要叫2h. 因为如果你搭档有4张h, 肯定叫了1h. 所以
你现在叫2h没有任何意义.
在这个之后, 你应该pass就是很容易想到的了.
别人能叫到5c, 肯定不是你的错. |

发帖数: 3277 | 49 you have already told your partner you hold a bad hand, around 6-10
, he still bids 2H, which means he holds a good hand, in the range of
good 15 to bad 18, thus you have to bid here and your hand is indeed
great cause you hold a singleton and great trump support in D, thus
there is no way to pass this 2H bid, and you should at least push to game
and slam is still possible, for example:
Sxxxx HAQx DKQxxx CA, the chance for 6D is excellent.

发帖数: 3277 | 50 actually 2H can be a good bid for xxxx AQx KQxxx A cause the hearts
are so trunky. If you don't bid 2H, partner may always worry about your
H losers with his weak heart holdings.
your
view
of you may have seen me in preempt actions, ok, let's exclude that), and if
I say this is
fit
It
