这是在俱乐部里打的牌。
四手牌如下:

首攻方块并连续攻三轮方块,结果5X-1.
如果防守松一点儿,不首攻黑桃的话,东西甚至能完成6定约。
看来,“五阶定约属于对方”也有例外。
是对的。

现在的问题是:在东显示双低花,西跳叫5后,北家能不能叫出5的牺牲叫?(基于同伴在2NT后直接叫出了4).

敌方花色没点不能加倍!这类牌叫就是输100!不叫可能500到600!加倍必须保证对方花色有点!这种情况实战极其多!如果我是老师,就把这几个例子给同学科普

5不是铁的,就如实战的防守,连攻三轮方块,就宕一了。

这个是针对1楼,南家的答案吧?
针对5楼的北家,是不是就很犹豫呢?

实战图:

由叫牌进程可以知道,对定约首攻和对定约的首攻都比较容易。这种畸形分布的牌,要小心又小心……
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

我总是这么分析这种类似局面:
1、我方如果是单张,要确保完成5阶定约联手要在23p,如果我方有缺门,联手要19p才能确保完成定约,否则就是需要根据叫牌来判断是否存在大牌的增值情况。
2、分析敌方也是这样,敌方如果是单张,要确保完成5阶定约联手要在23p,如果敌方有缺门,联手要19p才能确保完成定约,否则就是需要根据叫牌来判断是否存在大牌的增值情况。
3、敌方是否有缺门,往往无法确信,但是自己联手情况往往可以判断正确。
具体到这副牌,我方要想完成5s联手要23p,自己的ck是否能增值是未知的,因此显然自己完成5s定约机会不大。
再看敌方,双方牌力至少是相当的,因此敌方要想完成5h定约的关键是要有缺门,通过这么的逻辑思考后,根据临场的感觉再进一步分析,往往距离正确决定就不远了。

问题是:
1、5(可能阻击,可能想打,你如何判断?)后,北的加倍承诺对同伴花色(2NT表示红心和草花套55以上)地支持吗?什么牌力?
2、你会在同伴加倍5后,继续竞叫5呢还是PASS(象实战那样)?

这牌南家有凭大牌点力加倍的想法,
老师说加倍就是惩罚,pass就是逼叫,那么可以这样理解
如果南家此时pass,北家就必竟叫到5S吗?

沙师兄说的对呀,我记下了,真的记本子上了。
至于DVD朋友说的2S不该争叫我不敢同意。

在敌我双方将牌均配合的情况下,高阶加倍是合作性加倍,加倍者想竞叫而不能独自判断是惩罚好还是竞叫好,那么采用合作性加倍是询问PD,“我想竞叫,你认为是惩罚就PASS,如果也想竞叫就叫出来。” 很明显南家面对5H这牌有防守实力而没有竞叫实力,应当PASS,由PD决定是PASS还是加倍。

5级订约属于敌方,我不敢再竟叫5阶。
加倍是惩罚,pass是逼叫,我竟叫5阶。
沙师兄讲联手有空门19P即可叫上5阶,这牌我遇到以后肯定叫到5阶。

这个其实就是对opp的阻击叫牌,技术性x用到多少阶的问题,通常约定到4h或4s。但到5阶还技术x的就很少见了,所以5dx就是惩罚了哈。
