如果是这样呢?定约完成的概率也同样不低,但不能叫2S

第一个牌例比第二个要好的多。虽然两个都能开叫2S,但结果肯定不一样。
不知道是不是两个牌例都会叫进4S。

我以为此处的弱二开叫的概念需要厘清:
弱二是攻守兼备的描述性开叫,不是阻击叫。

得看你2阶开叫的范围,我相信BBO论坛里有不少人会说他拿这手牌开1S。
伯根的时代流行的是无下限的阻击,现在建设性的2阶开叫又开始流行了(2M=9-12,6张套)

这牌如开叫1S,对方叫不到4H。
—————-开叫2S,对方会竟叫的4H,但同伴会认为对方有4H做牺牲叫到4S(其实对方4H没有)。
—————-这就是10P,2个A开叫2S的结果。
这牌如开叫1S,敌我双方可能竟叫的3级,这将会是一个合理的得分结果。

第三家开叫,叫出1S也不错吧,这牌要有4H,那西家得有多少牌力,如果西家满足此牌力,4S会宕多少?
