lycier Posted July 9, 2014 Report Share Posted July 9, 2014 [hv=pc=n&s=sakq964ha9daj64c4&d=w&v=0&b=8&a=p1hp1sp2dp]133|200[/hv] 你准备叫什么? 很好的讨论题目。谢谢。首先,直接跳叫4♦作低花木,这是一个约定叫,但不一定都会如此定义。当然,3次低花木是公允的约定叫。1- 就算是4♦是大家心目中的低花木,我也是喜欢这样定义的,但我心理一直在犹豫:是否囫囵吞枣?请看下面几副北家可能存在的牌面: [hv=pc=n&n=sj4hq9876dkq32ckq]133|100[/hv] [hv=pc=n&n=s4hq9876dkq32ckqj]133|100[/hv] [hv=pc=n&n=s2hq9872dk752caqj]133|100[/hv] [hv=pc=n&n=s32hk7654dkq54ca2]133|100[/hv] 不难看出,当开叫人如果是高限14p+,这牌你只需问清楚关键张,就可以正确定约,似乎非常合情合理合法。如果是低限12p,开叫人持牌的大牌分布决定了定约满贯的成败。 2- 为何不mini-splinter:4♣? 如果开叫人·点力富富有余,那么你4♦问叫后咋叫咋有理,如果低限时,单张♣的有效性可就有讲究了,如果低限加之以♣上堆积了一多半hcp,只要opp大牌赢墩分布有利,恐怕结果凶多吉少了。 3- 兜不兜圈子,还要掂量同伴的理解性和基本功。为何不四花色逼叫-3♣,看看开叫人是否会信心满满地叫出3nt?也行开叫人的3nt对♦的大满贯是一个坏消息。为何不满贯前核查各花色的控制?满贯不是一厢情愿的试探! 这是应叫人作出决定前所必须的思考。 Quote Link to comment Share on other sites More sharing options...

000ffj Posted July 25, 2014 Report Share Posted July 25, 2014 这种牌远没有那么简单,2d后满贯机会极大,但是直接4d低花木,或者4c确定方块将牌绝对不是好思路,道理很简单,不一定要打44方块的满贯的,比如s6h5加上方块a一个赢墩就够了,就是说三套牌的满贯探求一定要非常小心,不一定非要打44方块的,这就是难点所在,比如[hv=pc=n&s=sakq764ha9daj75c8&n=s85hkqj54dq432ckq]133|200[/hv]你如果确定方块将牌的话,肯定无法叫到合理的6h或者6s甚至6nt了。或者[hv=pc=n&s=sakq764ha9daj75c8&n=s85hkqj54dq432ca3]133|200[/hv],这是7h/s或者7n,但是最多只能打6d这类牌就是我原先提到过的联手三套牌的满贯探求,如果体系不能很好地解决这类牌的定约,那就需要pd间更好的探讨了。 Quote Link to comment Share on other sites More sharing options...
