请问:
按哈代《21世纪的二盖一》,1nt开叫斯台曼问叫后,开叫者在3阶叫高花是表示该花色5张吗?

我曾见到过资料:1nt(15-17hcp)开叫,应叫3c是问5张高花。

喜闻你博学桥书,不应该请教这些问题,相反你可以系统整合后帖出来,至少你本人要消化好。这是我真诚的鼓励!

我尽所能回答:哈代21世纪教材,规定了1nt开叫有5张高花的三个条件,对后续stm答叫没有限定。按照我对哈代的理解,一般不会跳答三阶浪费空间,承诺在竞叫中再加一级。

关于开1nt后有很多流行的约定叫,其中stm后就包括你写的:贝尔约定叫,高限5张跳答三阶等;如果不用贝尔,就有机会用递进stm或SARS(用3c),类似你说的问牌型。
