逼叫性1NT应叫后(rediscovering 1NT forcing)

in the book "For experts only", edited by the Granovetters, there is a chapter by Kokish about "rediscovering 1NT forcing".

在“仅为专家”书中，有一章关于库克什“1nt逼叫后的再寻”。

One of the issues he addresses is how responder could be able to bid (discriminate) weak and goodish hands.

他处理的问题之一：如何区分弱还是强牌。

He suggests the use of some specific sequences, which at first sight might seem unnatural, but that after some thinking I was able to remember under the "lebensohl" heading.

他建议使用一些看起来像非自然的具体序列，像“莱本索尔”一样记忆即可。

The first "free" suit at the 2 level except a preference to opener's major, would be Lebensohl, forcing a puppet to next suit, followed by pass/correct.

在二阶首先是偏向于应叫开叫者的开叫花色，然后就是莱本索尔，通过一个傀儡式逼叫，然后PASS或者纠正。

 

There are a few sequences (when opener openes 1S and rebid H or S) when no "Lebensohl" is available, as 2NT is the only step.

It is conceivable, IMO, to use 2NT as Leb even in that case, since when we do have a balanced invite, we can play 3M in a 6-2 fit

有几个序列（当开叫者开叫1S并且重叫H或者S时），无法使用“莱本索尔”，这是可以理解的，因为我们可以做一个平衡邀请，可以尝试6-2配合的3M。

 

Some examples

一些例子：

1S:1NT:2C

....-2D "Leb"= Puppet to 2H, then P/C（傀儡至2H然后不叫或者纠正）

....-2H= normal

....-2S= 8-10 with doubleton spades (weak 3 card raise would go via 2D"Leb")

....-2NT = natural invite 自然邀请

....-3x = natural invite (the weak hand would go via leb)

 

 

1S:1NT:2D

....-2H "Leb"= Puppet to 2S, then P/C

....-2S= 8-10 with doubleton spades (weak 3 card raise would go via 2H"Leb")

....-2NT = natural invite

....-3x = natural invite (the weak hand would go via leb)

 

-------------------------------------

 

It seems to me that this fits well in the 2/1 version whenre 2/1 is absolute GF, since it becomes easier to show the invitational 1-suiter without bidding a 2/1.

我感觉在2/1绝对逼局时，这个序列很适合，因为他很容易显示邀请实力的一手牌。
