在4S和pass之间犹豫不决。局况仿佛倾向4S，因为对方的4H可以是很烂的牌在
加叫。本着相信同伴的原则我还是选择4S。同伴的牌很可能是
AKxxx / xxx / KQx / Kx
黑心4-1分布的时候打起来是很不舒服，虽然也不是全无可能。。恩，我又想pass了。
但是同伴也可能抓
AKxxx / xx / AQx / Kxx
6S都做得成！
2）x然后2H。这牌直接叫2H太强了些。当然如果叫牌进程到了
Ｅ Ｓ Ｗ Ｎ
１Ｓ x P 2D
P 2H P 3C
P ?
可能会有点不好决定。我一般是：when in doubt, go 3NT.
3）3D叫一口是明显的六张套，同伴可以改3H。这牌就算不是MP我也不会让对方打3C的
啦。
4）修正理解。同伴是强pass，我的AQ坐在高点力后面通通升值，那我应该叫5NT让同伴选择一个slam。
5）选择是加倍或者1NT。前者表示了红心， |

发帖数: 2804 | 3 Low C wins the case where partner has Kx or Kxx in clubs, but it loses when
partner has stiff club (not the 10). CA actually caters for both cases (but
gives up an extra under-trick when partner holds CK, which is OK since this
is IMP). However, as analyzed before, CA is never going to really gain
regardless of partner's club holding, unless declarer holds 3433 shape, but
the bidding indicates that declarer doesn't have that shape.
Therefore, neither CA nor low C is logical alternative.

capable of playing T or 9 from T9x, he still should play low to Ace because
it is the percentage action. T9 is only one layout, T9x is two (for example
T93 vs. K2 or T92 vs K3, they are identical. This is another example for
restricted choices, since with K32, the guy can randomly play 2 or 3 here,

发帖数: 2804 | 22 这其实是一副比较简单的牌。飞牌的选择主要是在黑桃或红心上。梅花上也有个飞牌，
但即使飞中了也不解决问题，属于practice finesse，BBO上经常看到有人做，但是应
该完全避免，至少在第一墩没有必要。
明手只有两次进手。我们先假设飞失的情况。
1）如果先飞红心被西家HK拿，接下去就用梅花进明手飞将牌，希望东家持黑桃单K或Kx
双张。
2）如果先飞黑桃被西家SK拿，接下去就用梅花进明手飞红心，希望东家持红心单K或Kx
双张。
两种情况看似对称，其实不然。联手有9张黑桃，东家持SK单张或双张的可能性远高于
红心单K或Kx双张。所以这种情况下以先飞红心为优。
在第（2）种情况，另外还有一种可能就是第二轮梅花明手用CJ飞，然后在CK上垫去HJ
，接下去再飞红心。总的来说也是小概率。
现在考虑飞成的情况。如果防守方都是诚实的，也就是说西家不会持K忍让，那么两种
打法差不多，但是先飞红心略好，因为飞黑桃的话需要用明手第二张梅花进手，存在被
将吃的可能。红心飞成之后庄家应该直接从手中出SA再SQ，对方不可能有机会将吃。

发帖数: 2804 | 30 同伴应该100%有SK。总不可能拿着 xxx Jxxx AJx xxx 在二阶加倍吧。
这牌就看你的目标是什么。如果满足于宕一，那么DK再D将吃是最保险的，当然SA再打
黑桃也是相同效果。如果是要争取最大利益，应该考虑低引黑桃。同伴SK吃进之后，有
以下选择:
1) 如果将牌为Jxxx或Qxxx，同伴会出第三张方块到你的DK然后得到一个将吃。
2) 如果将牌为Kxxx，同伴将兑现HK，然后继续黑桃。庄家只能用最后一张王牌将吃，
然后可以兑现C10，但来不及建立一墩方块，定约可以宕二。
实战中回的是梅花。幸好同伴的牌是：Kxx/Kxxx/AJx/xxx，定约仍然宕一。考虑到较差
的牌型以及缺乏中间张，同伴在对方1H之后作了个较为保守的1NT应叫。但我认为回梅
花太消极，给庄家一个时效。如果同伴将牌仅有Q或J的话，会送成定约。我比较欣赏低
引黑桃，保留住所有的选择，具体到这副牌，可以因此获得+500。 |

发帖数: 1151 | 33 保守（正常）的话选择S， 估计是算不上错的选择。
D是不错的选择， 不过D9， 还是DJ 有点头疼。 实战我应该是DJ（可能是致败的打法
， 譬如同伴只有Kxx； 或者如果同伴SAK而南家又不是S单张， D首功可能就送了一个
并不存在的小满贯。）。
理由如下： S的叫法估计同伴有一个赢墩吧， C的分布不论同伴有什么（K或Q）都不会
有赢墩（除非KQ， 或A）， 庄家不太可能打错（飞牌或者同伴有Q一定会亮相的）。
南家直拉6C估计H套坚强（同伴有大牌总是位置有利， 不需担心）， 庄家C甚至可能是
54配。 所以大致庄家已经有11墩在手了（5个C， 5个H ，D有一墩）。攻D的理由就是
期望同伴有DK并且位置有利建立一个赢墩。攻DJ是即使K位置不利还有可能飞明手DQ的
机会。
首功别的庄家都会有时机建立一个S赢墩（可能是SK， 或者南家可能的单张王吃），
拿到12墩。
如果同伴S KQ， D有A的情况下D就是差的选择。 但是如果庄王牌54的话，S首功也于事
无补。 |

be better than 3H in the sense of statistic rules: suppose you play for a

发帖数: 642 | 37 So the reason for not bidding 3C is likely due to weak suit. Anyway 3NT is
an easy make. If you like to create swing, the better chance seems to be 6NT

Qx
Axx
Kxx
T9xxx
It works when either S or C suit splits friendly. |

发帖数: 2804 | 38 This hand requires C splits friendly. In that case 6C will make too. Spades
are irrelevant: if you can take 4 clubs, you don't need spades split; if you
have to lose 2 clubs, then spades 3-3 doesn't help.
But on some other hands you may need to establish spade tricks. For example:

spade splits 4-2. |

Even if I lose this hand, I don't think my opp stands a good chance in a

4th seat 4S is generaly very serious. Hands like AKQxxxxx x Kx xx are very
normal. Here, if you open 1S, you may get passed out sometimes when partner
holds
one ace and short S. Hands like AKxxxxx Kx Kxx are very typical 1S
openers because you need quite some cards from partner to make 4S.If partner
