这副牌来自2013Baze Sr.KO杯赛
开室:



西家正是哈代书上的麦克·帕塞尔(Mike Passell),精彩的5431约定装置,给他们带来了令人兴奋的分分。

闭室:



结果是差强人意的3-2

他们输了10imps.这就是差距。

嗯,该约定叫我关注多年了,是在别的论坛上发现的,不过今年已经多次看到世界各国专家们使用该约定叫,而且都是赢分的,而没有启用的专家几乎都是输分结果。

要求是:
1- 10P+
2- 双低花任意分布5-4
3- 要求未叫的另一门高花的3张牌中有大牌点
4- 牌型是:5431或5440,5张分布的一定是低花,不允许是一门高花。

明白了?不清楚的话,请接着询问。

用了这个约定,就必须舍弃1NT后,3M表示6-7张破长套,通常有邀叫满贯的实力,满贯兴趣的原始的用法。

嗯,同意,这就看运气了,比如这次比赛出现的牌面适合于5431约定叫的时候,你就赚了呗;如果适合哈代的方式,那我们就赚了呗。
这就叫运气。
桥牌的运气最高可达惊人的33%,如果达到35%,那就形同赌博了。

bbo机器人就用的是5431约定叫。
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

没错,3张里必须有一枚顶张,否则不可以这样叫。
