发帖数: 20570 | 1 I think a natural 3S over 3D is probably fine. This is probably the only way
to bid 5-4 majors and strong hand. Also, 3S can be the only bid to get you
to 4S when partner holds some value and 3-3-5-2 shape.
Also, 4D is passable if partner is really broken IMO. I don't mind playing
it as generally forcing, but partner can really be broken sometimes and you
may not have a safe spot above 4D, especially after the redouble. For
example, AKQJ KQJx AKxx x. 4D here can be high if D doesn't break well.

发帖数: 20570 | 3 Sometimes, your hand is too strong. Sometimes, you just don't belong to 3NT
even if you hold 3-3-3-4 shape.
For example:
xxx xxx AKQ AKxx, it is absurd to bid 3NT over 1D opening with both majors
wide open and you have plenty of space to explore.
Suppose your partner holds x AKx Jxxxx QJxx, you can easily make 6C when 3NT
can easily go down after a normal spade lead and it is not clear for
partner to bid 4C over your 3NT.

发帖数: 623 | 4 哇，好久不来，这里居然热闹成这个样子。
虽然我已经miss了这个boat，但是仍然忍不住赶这个热闹。
两手牌是这样:
Kxxx

Kxxx
AKxx

Ax
Axx
Axxxxx

对吧？假定我们在同一page:
1D - 1S
2D - 3H （我不是太好的牌手，被BS没关系）
3S - 4C
4H - 5D
5H - 7D
4H: kickback
5D: 2 key + trump Q (I never rebid 2D over 1S with 1453 shape)
5H: confirm all key, asking for K
7D：we have all K's。同伴这里显然只关心K，否则他会做别的大满贯邀请。
这里大满贯的关键恰恰在于那个拿3个A，平均牌型的人，在知道同伴单张红心后要take
captainship,因为只有他自己知道自己是最好的2-3-6-2，而不是毫无前途的3-2-6-2
或2-2-6-3，即便前面的叫牌会完全一样。
假定同伴持这样的牌，没有理解我们的3H，把它当成了55GF，于是加一个4H，我们打

发帖数: 20570 | 5 I actually don't think it's merely a partnership thing. It is a matter of
evaluations and anticipations. For unbalanced hands, I would tend to bid 4S
with high ODR.
For example, with Axxx A xxx KQJxx, I tend to pass 4H, because this hand
contains at least about 2.5 (I offer some discount on the CKQJ because of C
length and opps' 4H overcall) defensive tricks, we are likely to beat 4H if
partner can also provide 1.5 defensive tricks; and we need partner to hold a
nice hand to make 4S.

发帖数: 20570 | 6 Here, if you don't play fit showing jumps, 3C is very acceptable.
5H is not absurd either if his partner shows a D void. His partner may still
hold something like: AQxx xxxxx - AKxx, in which case, 6H doesn't have to
be very good.
This 1-5-7-0 hand is almost the minimum requirement to bid beyond 4H. Of
course, if you don't like it, you can change HK to HQ.
Another hand is 1-5-6-1 shape, in which case, you want to cash CA. Still, 5C
should show CA or void for sound players.

发帖数: 2804 | 7 No good player will bid a non-descriptive 3C here. At least should bid 4C
splinter. So there is negative inference that South wouldn't have void in
clubs. Also, with 1570 shape, 5H is timid, to say the least. Opponents bid
and raised clubs to 4-level vulnerable, so at least percentage-wise, I won't
play for partner to have AK in clubs. In addition, holding AQxx / xxxxx / -
- / AKxx, partner should be very discouraged after 5C bid (also bad heart
suit is a concern), so he will not bid 5D. |

发帖数: 20570 | 8 This is about hand evaluation. After you cuebid 4S and 5C, Axxx Axxxx - xxx
is much stronger than AQxx xxxxx - AKxx. When you have to guess and I have
an approach to stay out of slams when facing the second hand, I have an edge

发帖数: 1151 | 17 我实际也是叫的4c。
我当时想的问题是这样的（因为叫牌， 特别是和网上随便得搭档， 很难有特别好得答
案。）：
小满贯基本上是板上钉钉了－－－不妨假设同伴是四个S吧。
问题是有没有合理得手段叫到满意得大满贯。 如果黑桃王牌得话， 是不是缺王牌Q 。
还有就是有没有可能兼顾方块做将牌得可能 （这个有点难度， 因为1D的不确定性。
实际同伴的牌是这样的：
S： JXXX
H： AKxx
D：KQxx
C： Q
我的牌：
S：AKT9X
H： 9
D： ATxx
C： AKX
结果：7S因为缺Q并且位置不利， －1。 7D是可以打成的 （D分布2－3， 无论什么防
守都可以打成； 当然情况比较特殊， C套大牌帮了大忙）。
同伴4H之后， 我问完AK， 摸了个7S（不知道有没有SQ； 可能应该问完A后直接问王牌
Q的）， 下了一个。 （当时摸的时候就想有没有7D的可能）。 |

发帖数: 1151 | 18 不妨问另一个问题： 能不能设计一个合理叫到大满贯（7D）的教牌， （2／1）－－－
同伴没有SQ的情况。
同伴的牌是这样的（同伴开叫1D）：
S： JXXX
H： AKxx
D：KQxx
C： Q
我的牌：
S：AKT9X
H： 9

3H - 3S
4D - 4NT
5S - 5NT

叫牌解释：
1D: 11-15, 2+D
1H: 自然叫或持强牌的接力叫
2S: 4张H的4441牌型，高限
2NT：接力
3C：4-4-4-1
3D：CRASH问A
3H：1个A
3S：CRASH问K
4D：加三级答叫，显示两个同色的K。南现在知道同伴是HK+DK。AK齐全，同伴还是13-
15高限，现在只露出1A2K，还应有至少1个Q，小满贯应该没有问题，可以继续询问Q探
询大满贯。
4NT：CRASH问Q。H和S都是同伴保证4张的花色，在4阶水平上叫这两个花色都是止叫，
所以必须越过去，用4NT作为询问叫。
5S：加四级答叫显示同级别两个Q，可能是SQ+HQ，也可能是DQ+CQ。现在南家有点犯难
了，因为自己一个Q都没有，同伴到底是高花2个Q还是低花两个Q呢？如果是高花2Q，我
要打7S；低花2Q的话，我要打7D。不要紧... 阅读全帖 |

发帖数: 642 | 20 Personally I don't like this kind of topic, since there is almost no correct
answer :)
For this one, Pass/Double/5H/5S can be right. 5NT/6D can also be the choices
if one is a little crazy. If north has something like
KQx
AKxx
xxx
Axx
slam is very good. But for most cases, 5 level may be too high. And even not
, at this case, it seems no way to ask pd to pick a major at 5.
At table, I would double. Pd will pass 99.99% of time, but if he pulls out,
I will be happy. |

发帖数: 2168 | 21 I can easily construct hands where ducking would be wrong: HK could very
well be declarer's 9th trick, e.g. he holds Axx/KQ9/xxx/AKxx
So I would just win. |

发帖数: 642 | 22 Yes, there are too many uncertainties. One important clue may be declarer's
choice of 3NT instead of 4H. With ATx KQ9 xxx AKxx, we can't say it is wrong
to play 3NT, but I would choose 4H.

发帖数: 2804 | 24 叫牌上面，2C不可取，但是可以考虑加倍1D。不过D10可能是张好牌，1NT也是可以接受
的。
既然左手显示了CQJ（多半从类似QJTx中攻出来），右手应该有剩余的全部大牌点（DJ
尚不确定，但也是在右手家的概率较大）。如果右手有AKxx四张红心，定约几乎绝望。
所以右手红心不能超过三张，大概需要3-3-5-2或是4-3-4-2牌型。先拔掉两张梅花大牌
，然后打一张HQ看看。 |

发帖数: 2804 | 25 同意。基本属于均型，牌力牌型都符合1NT开叫，更重要的是有一半点力在短套。如果
开1D，同伴应叫1NT的话没有合适的再叫，除非你有类似Cole或是Gazzilli的手段。
把牌改成 AKxx Jx AKJTx xx，则以开1D为好。 |

发帖数: 182 | 27 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
