没赢墩来源,点力太分散。

戈伦说了:4333牌型,-1p,没Ace,-1,结论很简单吧:自然体系pass,想也不要想;精确体系有定约,开1D

任何位置都pass
虽然有12HCP,缺少两个防守墩,也没有指示首攻的花色。
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

我选择开叫1D。
1.(按劳伦斯的《二家PASS后的叫牌》中的说明,好像是开叫1N。。。。)
2.二家PASS后,一般要降低点力及牌型要求积极进取开叫,理由也较充足。
3.开叫将有效破坏OPP的正常叫牌进程,
4.来自同伴的任何应叫品都不会让你处于难堪地步。

1D,不开口没机会了。最少剥夺了第四家开叫1C、1D的叫牌机会,如果他的牌型又不适合技术性加倍,又不够1NT,没有长套,也只能PASS了。

不开,单有局,搭档没开叫实力, 用一个低花弱套开叫不如隐藏实力好些;如果敌方开叫后搭档能争叫一轮可以考虑加叫搭档一次,然后不叫

科恩拿着《叫还是不叫——总墩数定律》书稿给哈曼看,哈曼提笔就把不叫给划掉了,叫!叫牌是勇敢者的游戏,如果排除MP和IMP,有局和无局及其他影响因素的话,毫无疑问地开叫!当然,如果你是怕死型,你很可能面临二阶是否要平衡的问题,相信你知道二级平衡的风险,所以贯彻你前面的方针,你还是PASS算了:打MP不就是一副牌;IMP不就是个部分定约吗?

Hi
大家辛苦了,现解答如下:
南家即使在第三家,也不该开叫的。这手牌不符合20法则(更何况20法则远没有那么完全可靠!) 。

整手牌无A无10,使得这手牌的估值变得很糟。

或问:难道第三家不应该轻开叫吗?

或许能开,但是这仅在有一个良好的的理由时,才会如此。

如果这牌开叫1D几乎没有阻击价值,而且甚至都不是渴望同伴首攻的花色!所以应该Pass!

谢谢楼主的解答,这题之前我会选择轻开叫1D,以后遇这类牌也会坚决选择PASS

我还是选择开叫,我希望同伴能加叫方块,或者自由应叫1阶高花,如果第三家不开叫,我自己和同伴都可能没有机会表达自己的牌

唯一的坏处的:本来是4家pass的牌,最后我们被迫牺牲敌人的部分定约,有局下1,下2

温故知新,其实这就是估值;一手牌的估值技术与你的经验密不可分,是真实的牌技水平表现。估值不等同于计算hcp大牌点,hcp大牌点是静息僵硬的,而估值是有生命力的经验与认知的判断,随着叫牌的进程---不论有无争叫,又处于动态的。希望朋友注意学习,估值计算是牌技水平的核心。

PASS是合理的选择,如果出于战术需要第3家开叫1后就永远不叫,希望同伴不要把牌叫得太高

今天我们在讨论估值和牌理上都作了很多的有益尝试,那么现在的你在温习该帖时,再次讨论该帖,是否依旧坚持开叫?

对不开叫表示无法理解,一个废点都没有的12点,还有3个K,两个9……

不是所有的12p都值得开叫,我觉得没有两枚赢墩的开叫,很会欺骗搭档,除外图穷时的策略性开叫,还要征得搭档约定同意。这和精确体系不相为谋。
