当你拥有如下这幅漂亮的牌面时,你将选择如何开叫

问题1、你选择开叫1S吗,后续打算如何再叫
问题2、你选择开叫2NT吗,后续打算如何再叫

我选1S。同伴pass。我争取超两个。

同伴叫1NT。我叫2NT。

这道题是一个难题。我觉得不论如何开叫---1还是2nt,都瑕不掩瑜的,都有丢局的时候。

如果两套是低花。怕就是开2NT了吧?

开叫1s是肯定的,当你看了下册中很多1M-1n-2N(52页例46)牌后,你甚至会觉得你的这种加叫牌力还稍显不足,有一种冒叫的感觉,因此完全不需要担心开叫1s叫低了。

当手中持有半壁江山时,有的时候,牌情是很微妙的。比如:
你开叫1吧,同伴持有:

S:XX
H:KXXXX
D:XXx
C:JXX

好了,开叫1后,opp连带同伴都会有可能pass,结果是丢局的。
这也就是因为这个缘故,持20P均型含五张高花不敢开叫一阶的原因所在;而持非均型时,别人争叫的可能性也会大增,开叫1S也更有理。

在我的概念中是不考虑5-4套开2nt的。尤其是s5-h4。

如果能接受开叫2nt,唯一的因素是DKx。

担心开叫1s会丢局是可以理解的,但开2nt宕3也需要谨慎。

学习了——
54或45高花套不在开叫2NT的范围内————可以这样理解吗?
