arter Posted January 23, 2013 Report Share Posted January 23, 2013 前两家低花不会太长。也没有高花弱二的牌面。虽然如此。我还是会叫5D。毕竟局况有利。敌人的高花配合让人压力太大了。 Quote Link to comment Share on other sites More sharing options...

the_clown Posted January 23, 2013 Report Share Posted January 23, 2013 I would try 4♦ at MP. I am not too worried about missing game and 4♦ gives them the chance to go really wrong. Usually when I open 5 all they can think of is double and I get a score at the bottom of the field. Quote Link to comment Share on other sites More sharing options...

Usually when I open 5 all they can think of is double and I get a score at the bottom of the field. 这位朋友的贴子大意是：打mp，我愿意开叫4♦。我是不太担心丢局的问题，而这样开叫的好处是给敌方一个真正犯错误的机会。通常当我决定5阶开叫，敌方所考虑的是加倍，我也因而会得到一个底分。 Quote Link to comment Share on other sites More sharing options...

However, a hard thing is we play namyats convention,so no way to open 4♦http://www.bridgebase.com/forums/public/style_emoticons/default/sad.gif Quote Link to comment Share on other sites More sharing options...
madongjun Posted January 23, 2013 Report Share Posted January 23, 2013 我会叫1♦，然后在竞叫过程中，叫出草花，最后可能是以低花牺牲对手的高花，运气好的话，能赚取一个加倍的低花局分。 Quote Link to comment Share on other sites More sharing options...
cqwbc Posted January 23, 2013 Report Share Posted January 23, 2013 我支持开叫4♦。我来谈谈我开叫4♦的理由，就是为了有机会更好地描述♣套，非等长畸形牌（7-5牌型甚至8-5牌型），开叫4♦就是给opp空间叫出4M，我再叫5♣，这样叫同伴是不会理解为6-5牌型了，也为PD更好地估值牌。如果开叫5♦pd在非♦上的牌值如何估值呢？开叫1♦最大问题是opp迅速达到4M后你再叫5C是6-5还是7-5牌型，pd很为难，估算输张就会出现偏差。综上所述，我支持开叫4♦。 Quote Link to comment Share on other sites More sharing options...
zyp163 Posted January 23, 2013 Report Share Posted January 23, 2013 I tend to bid 2C.tell pd I would play this hand but opps. Quote Link to comment Share on other sites More sharing options...
lycier Posted January 24, 2013 Report Share Posted January 24, 2013 I tend to bid 2C.tell pd I would play this hand but opps. You meanings is you want to open 2♣? I disagree that style with 6 loser. Quote Link to comment Share on other sites More sharing options...
wuhuan Posted January 24, 2013 Report Share Posted January 24, 2013 英语很差看不懂但还是参与一下————叫4D不会被误会为纳米亚次约定转4S吗？叫1D很可能叫不到愿望中的满贯，中庸一点还是叫5D。 Quote Link to comment Share on other sites More sharing options...
FyxShen Posted January 25, 2013 Report Share Posted January 25, 2013 即使4D不是约定叫，也还是5D更好。 压力和猜断留给对手，不要留给自己，特别是白对红的第三家。 这牌如果1D开叫，假设你准备跟到5D，那么对方5M之后，拍还是不拍就不好办了。 Quote Link to comment Share on other sites More sharing options...

3ntmk Posted January 25, 2013 Report Share Posted January 25, 2013 我非常遗憾，大师为什么这么 快就给出答案。强烈建议另外发帖给出答案。 希望大家不要嘲笑我的巧合。我完全考虑了自己的思想和大家提到的可能会遇到的困难，但正如答案，考虑进去了。 大家给出了不同的开叫方式。但我很疑惑，难道牌面不是非常准确，合格的1D开叫吗？因为多了长度，有个牌型，会动摇根本吗？开叫1D保留了所有的机会。正如数学家所言，这是个数学游戏：你不可能永远指望别人犯傻、犯错，力争叫好自己的牌，才是方向。 开叫1D，再叫1-2次C，基于如此的长度，只要C少许的支持就可以保持竞叫，D是独立套无需支持。我会一直在配合的C或不配合的D上竞叫至6阶，除非同伴惩罚对方的5阶高花定约（对方单有局）。怎么会是本手牌加倍5H?
