贴几个牌例，请教选择及理由

[qlpsecond]

2/1体系，对手自然

LHO partner RHO you

1D 1NT 3D ？

RHO的3D承诺5+张方块、实力6-10，阻击性的

持牌xxx xxx xx KQxxx，怎么处理？理由？局况敌方单有。

 

partner RHO you LHO

1NT pass ?

持牌Axx J AJ86 JT852，局况我方单有。

NT结构太多，所以讨论的前提不是很充分。这里要请教的是，如果你的3M设定为“低花5/4或者4/5、所叫高花单缺的逼局实力”，这牌你3H吗？3NT？选择的理由呢？

 

RHO you LHO partner 局况双有

1H pass pass double

2H 3D pass pass

//

partner的牌是JT9x T KQxx AJ9x

讨论的内容---partner是不是应该探索一下进局可能性？如果应该，怎么探索？

 

谢谢！

Assuming the NT range is 15-17.

 

1) If RHO does not raise to 3♦, I believe the normal action will be pass. (Not sure if some really aggressive players will invite under this vulnerability).

 

When RHO raise, partner's ♦ length and HCP is expected to be smaller and the probability that you can bring in the ♣ suit runs is higher. So you can certainly construct hands which 3NT makes

 

(♠J10xx ♥AQJx ♦Ax ♣Axx)

 

I think the hand might worth an invite if RHO raise to two level only which hope to stop in 3♣ when partner is minimum. Certainly we cannot do this now. The hand constructed will always require partner to have 5 quick tricks (including ♣A). I vote for a pass. But I am not surprised if some choose to bid 3NT at this color. Another concern is that partner may not have real ♦ stopper.

 

 

 

2) This is a classical 3♥ hand. If you choose to bid 3NT instead, you can give up this convention and adopt other for 3♥.

 

 

 

3) Another difficult decision. Depends if you have some gadgets/agreements here to differentiate a competitive 3♦ or 3♦ with constructive values. I think your hand is not much stronger than the typical reopening double over 1M to take the auction. But game is on, say partner have

 

♠ xx ♥ Axxx ♦ Axxxxx ♣ K

 

Again I think the first issue is the partner expectation over this reopening double.

我的观点

 

1) 我会pass，自己看不到订约，耐心防守

 

2）5431约定的话，我会3h 的，寻找3nt ，基本上有安全退路的。

 

3）这个3d 是如何理解的，竞叫，还是表示实力的！假如探索的话，安全性如何？

Yes,I totally agree with you.

 

1- pass since I think pass in this situation is a good option ,even maybe we get not good result.

在这种情况下，pass是一个好的方案，即使也许会有差的结果。

 

2-3♥ is only a decent choice,and it can describe your hand clearly -- only a bid! what else?any idea? J value？

3♥一口气把牌情描述清楚了，还会有何不妥？

要考虑J的估值？

 

3-yes,difficult to make next decision.I think it depends on you bidding strategy.

是的，很难抉择，我想这取决于牌手的临场叫牌策略。
