这是一道基础叫牌练习题。在应用MTWS时,目前大家基础约定知识都已经掌握得不错了。
当你持南家牌面,你现在该如何选择:2先逼局?3表示六张的满贯兴趣?还是别的着想?为什么?

注意:不要企图看四家的持牌图而去索骥。

我选择4s。手持边花控制弱的半均型,在同伴的1nt后,不报太大期望,简单封局。

先2D逼局后再叫3S表示一手垃圾牌面,显然这手牌持一手纯净的S套不能叫2D。
3S显示有满贯兴趣,持一手纯净的S套,然而同伴持低限均牌时,你的边花对同伴的帮助不够。不可能想满贯的。这手牌还是直接4S止叫吧。
正确的判断来自经验,而经验常常来自错误的判断。

寻找自己的错误才是学习桥牌的唯一进步方法

还是香港大师说得对,说的简单明了。分析一下:

1-叫2逼局?
目的何为?尽力寻求配合?必须尽量选择4为最佳进局方式?
2-叫3满贯兴趣?
你没牌型,又控制很少,开叫方再叫1nt是限制性的,且牌面均型,满贯前景还要乐观?
3-正如香港大师所言,最怕同伴持 AQQJQJ 要選擇3NT。


临场时千万别忘记了,二盖一的进局选择是优于其他体系的优势,充分利用这点。
If you have a choice of reasonable bids and one of them is 3NT, then bid it. Known as "Hamman's Law"

哈曼法则:如果你可以选择一些合理的叫品时,其中之一是3NT,那么就叫它!



哈曼法则怎会轻易忘失呢?


只有从心底里面对约定叫有了深刻的理解,
则约定性叫牌体系才是一把犀利的战斧,
否则就是一场灾难。
