考克什(Kokish)进局试探结构

 

(原文来自www.pitbulls.shawbiz.ca,Aihua译)

 

打伯根式加叫能为你们的高花进局试探结构增添新的内涵。了解到同伴有三张支持,你可能更愿意做3NT,而不做10墩的高花定约。试局的目的不仅是叫到局,而且要叫到正确的局。我喜欢考克什(Kokish)的进局试探叫,它们是很好的探索工具,能找到正确的局。

1H-2H6-9点,准确的三张H支持

2SKokish进局试探——所有花色的长套试探叫,问同伴是否接受邀请, 准备接受那个长套的进局邀请

2NT:接受S的长套邀请。开叫人可以3H4H止叫,或者再叫花色做第二次进局试探或开始扣叫

3C:接受C的进局试探但不接受S的进局邀请

3D:接受D的进局试探但不接受S/C的进局邀请

3H拒绝接受邀请

4H/3NT接受所有花色的进局邀请

2NTS短套试探或更好

3CC短套试探或更好

3DD短套试探或更好

3HH短套试探或更好

3S6-4套或点力极端集中的5-4

3NT5332,不逼叫

4H:止叫

1S-2S6-9点,准确的三张S支持

2NTKokish进局试探——任何花色的长套试探叫,问同伴是否接受邀请,准备接受那个长套的进局邀请

3C:接受C的长套邀请。开叫人可以3S4S止叫,或者再叫花色做第二次进局试探或开始扣叫

3D:接受 D的进局试探但不接受C的进局邀请

3H:接受H的进局试探但不接受C/ D的进局邀请

3S 拒绝接受邀请

4S/3NT接受所有花色的进局邀请

3 CC短套试探或更好

3 DD短套试探或更好

3 HH短套试探或更好

3 S:阻击性,六张套

3NT5332,不逼叫

4S:止叫

通过这些叫法获得的信息可能使你更愿意叫3NT而不是4高花。你通常叫的是有实力的花色,而这可能更宜于将定约引向3NT定约。如果你有点象彼得·琼斯(Peter Jones),总是碰上坏的将牌分布,那这个进局邀请结构可能就更有用了。

我想象不出在伯根式3D加叫之后怎么试局。总不能用跳到局来作为进局试探叫吧!!而在伯根式3C加叫之后,我猜想,你可以发明几种试局叫法。也许,3D叫品可用作以大牌点为基础的一般性试局。要是试S局,你也有可能打H定约,你可以为相应的叫品规定含义。

 Kokish Game Tries

PITBULLS :  

       Playing Bergen raises adds a new dimension to your major game try structure . Knowing that partner always has 3 trump makes 3NT a powerful alternative to a 10 trick contract . Getting to the right game can be considered as well as getting to game period .  I like the Kokish game tries as a good exploratory tool to find the right game.

1 H-2 H: 6-9, exactly 3 H.

2 S: Kokish Game Try, a long suit trial in any suit, asking partner which Game Try suit she would have accepted.

2 NT: Accepts a game try in S. Opener now signs of in 3 or 4 H, makes a second game-try by bidding the suit or starts to cuebid.

3 C: Accepts a game try in C, but not in S.

3 D: Accepts a game try in D, but not in S/ C.

3 H: Rejects all game tries.

4 H /3 NT: Accepts all game tries.

2 NT: x/- S, Short suit Game Try or better.

3 C: Short suit Game Try or better.

3 D: Short suit Game Try or better.

3 H: Preemptive, 6 card suit.

3 S: 6 4 or extremely concentrated 5 4.

3 NT: 5332, proposal to play.

4 H: SO

1 S-2 S: 6-9, exactly 3 S.

2 NT: Kokish Game Try, a long suit trial in any suit, asking partner which Game Try suit she would have accepted.

3 C: Accepts a game try in C . Opener now signs of in 3 or 4 S, makes a second game-try by bidding the suit or starts to cuebid.

3 D: Accepts a game try in D, but not in C.

3 H: Accepts a game try in H, but not in C/ D.

3 S: Rejects all game tries.

4 S:/3 NT Accepts all game tries.

3 C: Short suit Game Try or better.

3 D: Short suit Game Try or better.

3 H: Short suit Game Try or better.

3 S: Preemptive, 6 card suit.

3 NT: 5332, proposal to play.

4 S: SO

The type of information obtained by these bids can lead to 3NT instead of 4 of a major . You are normally bidding values in that suit and that could lead to 3NT.  If you are like Peter Jones and have a propensity for bad trump breaks then this tool would be very useful.  

       I can not see making a game try over a major Bergen 3D bid . A game try should be a jump to game !!   A Bergen 3C raise you can invent some game tries I guess. Perhaps a 3D bid can be a general game try based on HCP . With spades you also have hearts to play with so you can invent a meaning for that bid .
