bluejacket Posted April 14, 2013 Report Share Posted April 14, 2013 属于中2开叫范围了 Quote Link to comment Share on other sites More sharing options...
zyp163 Posted April 14, 2013 Report Share Posted April 14, 2013 [hv=pc=n&s=sat9872hq2da97ct2]133|100[/hv]如果是这样呢？定约完成的概率也同样不低，但不能叫2S Quote Link to comment Share on other sites More sharing options...

madongjun Posted April 15, 2013 Report Share Posted April 15, 2013 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。 Quote Link to comment Share on other sites More sharing options...
lycier Posted April 15, 2013 Author Report Share Posted April 15, 2013 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。 Quote Link to comment Share on other sites More sharing options...
yunling Posted April 15, 2013 Report Share Posted April 15, 2013 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） Quote Link to comment Share on other sites More sharing options...
wuhuan Posted April 15, 2013 Report Share Posted April 15, 2013 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。 Quote Link to comment Share on other sites More sharing options...
601821297 Posted April 15, 2013 Report Share Posted April 15, 2013 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？ Quote Link to comment Share on other sites More sharing options...
