发帖数: 623 | 1 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.

This does not meet your criteria for 3C preempt so you passed. So did LHO.
Pd opened 2D, multi (but only weak2 type).
RHO also passed (they play option 2 of the ACBL defense, i.e, x is takeout
for S and 2H is takeout for H), and you bid 2H, pass or correct.
LHO now surprisingly came in with 2S, and pd passed. RHO bid 3H. You have an
easy double. Although undiscussed, this is unmistakenable as pd can take it

这点上我还是同意bucky的，尽管3H确实有点overbid，但2H叫得太弱了，pd的double只
要是正常的t/o，且没有废点在黑桃上，局基本就有了，叫2H肯定漏掉

停在3n肯定没有错，如果倒了，责任也算是北家的，但我认为4H还是有一定道理的
因为如果北家是黑桃A一止，而红桃上是jx或者jxx，3n肯定倒了，而即便在北家jx的情
况下
4H仍然有的做，但是改叫4H后，如果倒了，责任就是南家的

这点取决于怎么看待这个4H，像版主所说的红桃KQJxxx，叫了3H后，再3n，只能叫4H |

发帖数: 228 | 14 个人意见：假设开15-17的带5高花的1NT，那么1S然后2D(H)再叫要么是低限均型或半均
型或者非均型，要么是中限半均型或者非均型牌。
第一第二个例子，牌力9-10点，对着同伴的低限牌几乎没有3NT的可能（第一付也许方
块配合能稍微多点机会，总体上也够呛，要是剩下两门花色有结构，可以考虑冒叫一点
），在这个前提下，回到2S是安全第一的选择。这个时候叫2NT通常要有11-12分的牌力
比较合适。如果同伴真的是中限实力，同伴会从2S里面拉出来，例如2NT，3X等，一般
来说丢局的可能性很小。
第三个例子说不准，同伴低限55，2S后也叫不动，而的确也有2H打成2S宕掉的牌。看感
觉吧。估计2H，2S，3H都有人选。 |
|
b***y
发帖数: 2804 | 15 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
，结果同伴2S，右手3H，左手4H，做成５个。;-)) |

发帖数: 147 | 16 我对鸡肋的看法:
1.3H成局前景大，风险也很大。如果同伴S不短，H不是6张，并且H偏分，-800也是可能
的，所以是肉多骨头硬。
2.2H是没有前景的，舍不得的只是大牌点，用以防守一样有效，这是肉少骨头多。
查了一下National的记录(MP和IMP第23副):
http://www.acbl.org/nabc/recaps/2010/01/13/
东西得110或-100，-200大约有30%，多数应该是叫了2H的，建议这些选手认真学习11楼
文件，写得非常好。 |

是这样一手牌。 |

1S , 自愿应叫 5-8 点。
2S, 跳叫， 9 + ， 试探进局。
3S, 牺牲叫， 不好是好叫品。 敌方不一定有局，同伴，有可能16+ 点。 再说你是高

2) 3NT.
可能叫品： 2NT, 2H, 3C, 3H
2NT, 低限均牌 12-13 点
2H, 低限不均牌， 6421, 5431, 12-13 点
3C, 不均， 至少 5-5， 可能6-5。可能 12-15 点， 关键是牌型。
3H, 高限。 红心至少6张。
注: 同伴逼叫， 一定要表达点力， 要不然会丢惯。
3）这牌争议肯定大， X -- 假如双方约定， 这不是penalty.
可能叫品: X, 4C
X, 不放过 3 NT 机会。。。。你只要同伴14 点，就成局在望。有可能冒叫。
4C, 这个就不用解释了。

First, north's hand is slightly weaker than a 3 C overcall. Suppose north

the only sensible choice for south is to double. Now north can bid 4C to

发帖数: 2804 | 24 1.应该这样看：如果对方有8张以上配合并且停在二阶，你应该倾向于平衡。这并不是
说平衡一定是对的，但你PASS的话需要有足够的理由支持，比方局况不利，牌型不好，
等等。而平衡则不需要太多理由。但是有很多序列虽然停在二阶，却可能是失配的，比
方1S-1NT-2H-2S这种，往往放打是正确的，平衡需要特别小心。再有就是，我一直强调
一阶竞叫条件可以放宽，这样我方在平衡位置的压力会小很多。
2.强/弱自由应叫各有利弊，是在对方简单争叫的前提下。当对方阻击争叫的时候，比
方这里所说的1C-(2H)，自由应叫应该逼叫一轮，10点以上，这基本上没有争议。 |

发帖数: 2804 | 35 Well, one of the reasons is that, they feel the hand was close to bidding 3H
earlier (but only Weinstein and Moss actually do it), so they need to do
some catch-up. As I said, 3H can be made with only 3-card support, and a
worse hand in general. These days people open very light (I am not saying
this is good, just a statement of fact), so this hand is quite good in that
context. I think when it comes to individual partnerships, you really have

发帖数: 2804 | 42 There are different schools of 2/1. Some play that 1H-2m-2S doesn't show
extra value, then H-S-S would show 5-6, strength undefined. Others play that
1H-2m-2S shows extra (although it doesn't have to be as strong as true
reverse), so H-S-S would show 5-6 and strong hand, while H-H-S shows 4-6 or
5-6 weakish hand. Another factor is whether 1H-2m-2H promises 6+ cards. If
2H rebid doesn't promise 6+, then with many 4-6 shape you would just rebid
3H again, unless your 4-card spades are strong. |

能地显示两门高花，点力不足邀局的时候，先1S再2H是最佳策略。
应叫1D的问题在于，如果同伴是普通的加倍实力，持一门或两门四张高花，你1D之后可

实力，基本报请了点力和牌型。
BBO上还有一个常见的问题，就是不少牌手认为同伴对于加倍的花色应叫（比方1S）是
逼叫的。所以经常看到拿着12点在同伴加倍后只叫1S，而同伴拿着低限的牌又再叫1NT
或2S等，一个低叫一个猫叫，结果也是正正好，负负得正。 |

发帖数: 2804 | 47 BBO上特别经常地看到以下两个序列被滥用，觉得有必要讨论一下。
假定叫牌如下，对手没有插叫：
（1）1NT - 2D - 2H - 4H
（2）1NT - 2D - 2H - 4NT
你认为应叫方大致是什么牌，最后叫品（4H或4NT）是什么含意？
希望大家踊跃勇敢地发表自己的想法，我们这个版面不能仅限于中高级以上牌手发言。
尤其是这类问题，我很想了解一下爱好者中的普遍认识。 |

如果就是纯自然叫牌，我对1NT-2D-2H-4H 有问题请教
1、应叫方如果是白皮的话，你俩就17点，为啥要转换？为啥要抢2H？我的理解是不能
转换，也就是说转换叫有点力要求
2、开叫方，就两张弱H，为啥必须接受转换？
3、为啥要有6张才能转换？这样的限制会不会丧失部分订约机会？毕竟5-3出现概率大
于6-2，6-3概率
我的理解是自然1NT后，牌型牌力很清楚了，如果同伴仅仅10点以下的牌的话，以后叫
牌过程要在开叫方掌控中。

1D 1S 2H 2S
P P ？
2H = 至少五张，逼叫一轮（一般10+点，好的牌型可以降低到8+）
你的以下叫品是什么意思：
3C （是否逼叫）
X
2NT
3S |

发帖数: 2804 | 50 3H can almost never show 3-card in this sequence. You would have either
raised to 2H earlier, or started with 1NT.
It is impractical to require honor-doubleton. In sequences like 1H-1S-2D-2H,
there is no such requirement, why require it with 1H-1S-3D? Plus, 3H saves
room, it should be the default bid. |
