after 1d---1S:

1-you rebid 2nt? can you not promise a belanced hand? how to define 2nt with unbalance if agreed?

2-directly bid 3nt? For me,it shows a solid D suit ,18hcp with singliton in S.

3-jump to 3C? can you promise cards of suits?

 

Thank you very much.

 

这是我在专家级论坛出的题面。

在1 --- 1 后:

1-你再叫2nt?可否承诺均型?如何定义2nt?

2-直接再叫3nt吗?表示18P+或强牌持有长套赢墩来源?

3-再跳3?你可否承诺所叫的全部花色张数?

常规逆叫2不简便? :rolleyes: :rolleyes:

 

实际上,这也是一部分专家的着想。不过,如果谈到逆叫,有的人设计是:开叫,应叫1后,再叫2更为节约时效。而直接逆叫2所带来的张数困惑,即:极易导致同伴对第一开叫花色的长度误会。

由此可见,lycier对体系的研究是相当的广泛而深入。

 

4441的强牌的确是自然体系比较含混的地方。lycier已经给出了选择方向,如果任由大家发挥,答案一定很多。我有两个想法:

 

1.为了保持与哈代思想的接近,选择2NT再叫。因为逆叫2H没人能假设是等长的4-4,跳新花在哈代的1高花开叫后加叫逼叫性无将中全部是5张。这里2NT也比照Meckstroth,表示18-19,但不保证均型,也不保证到局,同伴可以PASS。3C是人为示弱叫,3D是寻找高花的FG,3S是6张的满贯兴趣,3H是高花5-5的满贯兴趣。

 

2.结合前面的体系框架讨论。我觉得可以引入多功能2D,这其中就包括4441型的强牌,http://bridge.ustc.edu.cn/yjjd/04_52.htm

其实我原来也是感到有些棘手,有一天和3ntmk搭档,他就是持4441强牌再叫2nt的,最后我们当然止叫与3nt定约而获得成功。这不得不引起我的深思。又经过专家级论坛广泛求助,我觉得我们由于拥有沃尔夫止叫信号工具,后续处理轻松如意,那么再叫2nt优势历然,优点就是简化复杂的局势,最大限度减少了误会。也许你不同意,这很正常,但是两权相害取其轻,依然是当前牌面的较好的选择。

今天,我和sleekrain搭档,同意遇到4441牌面,

Lead 5,结果超2。

 

同样地,这牌估值18p,在我眼里绝不是17p。我的意思是说:简化叫牌还有有意义的。
