9+赢墩的坚固高花套,哈代大师在《21世纪的二盖一》下册介绍开叫2后,跳再叫3高花。要求应叫人扣叫A。
同时,只有8赢墩的坚固高花套,开叫2后,跳再叫4高花来表示的。
这牌正好开叫2后,跳再叫3。一下子把牌叫清楚了。
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

啊,孙老版说得不错啊。
然后,那都是一般情形下的故事。
比如:opps用,尤其是用强烈地盖叫你的后,你敢加倍吗?你不加倍吧,同伴也会因你开叫2帮你加倍呢?
一个问题出来了,那就是你有多少防守实力?
说句大白话,敌方坐庄S花色定约,依你这牌的防守实力,可否打得opps狼狈不堪?

说的也是——如果此路不通那就准备做开叫1H后再叫3D的打算了。

有纳米亚茨4c这个叫品可以参考。

行情变了,不行了,哈代的方法是用少个K绝不少A的长套做纳米亚茨--赌博3nt开叫的,优势在于开叫率是这副牌的两倍。
就是说,这牌开叫4C比纳米亚茨所定义的花色套还要好,开叫不符合定义;当然,你和同伴有这样约定,那开叫4c没问题。

开叫2及其后续叫法是本手的叫法。如孙老板所言。
如果担心防守赢墩不足,对方用更高级的黑桃花色盖叫,那就只能凭判断决定叫或者不叫到5阶以上了。
两相比较,宁愿开2,然后再根据对方和同伴的叫牌决定取舍。

开叫2C,同时威慑敌人,让敌方知道如果他们敢乱叫就可能遭到沉重打击 :P

这正是人的炫耀力量的天性和弱点,不惟业余者。
这种着想恰恰违背了现代桥牌的叫牌理念:
1-开叫强2不是为了炫耀自己强牌而去打广告!
2-只有需要才去开叫2
3-强2开叫决不允许心理叫!

曾经见过OPP开叫强2C,我方轻松完成6SX=的 ;)

:( 吓不到也开2C,下次跳4H,这时搭档就知道你就一个坚固套别无它物

难道开叫4nt?问不到ace的话就打5h,这个5h如果无法完成的话,敌方多半也有4s或者5c.

同意直接4NT问A。如果牌例中S套和H套调换过来,开2C。

不选择1开叫的都是怕同伴给pass掉,同意楼上所说开叫问A的方式。

不符合实际战况,理由不充分,这样的畸形分布,阻击性竟叫很凶的,不必担心pass问题,即使同伴pass,对手也很难闭嘴的。

如果自己手里大牌点再低一些的话,比如13或14个点是不怕被pass掉的。手里拿着17个点9赢墩开1,还是有些担心丢局的。

开叫1H,漏局是不会的,就算同伴没点,敌人也不会让你打1H的。但是有个问题是值得考虑的,与开叫2C相比,开叫1H更容易让对方争叫出黑桃,这是你不愿意看到的,所以开叫2C是更好的选择。

2C开叫是本手,4S后的高价判断需要PD的默契。

很纠结的,考虑概率开个1H 大概错的机会要少些!
