xhq Posted September 22, 2013 Report Share Posted September 22, 2013 假如你是北家持牌如下:[hv=pc=n&n=s4hqj865dakt432ck&d=n&v=n&b=5&a=1hp2cp2dp2hp3dp4dp]133|200[/hv]现在轮到你叫牌,你采取何种行动? Quote Link to comment Share on other sites More sharing options...
000ffj Posted September 22, 2013 Report Share Posted September 22, 2013 这就是我曾经提到过的延迟性加叫,3套牌的情形,其实这种情况是很多的,这副牌是明显的2套配,有时候是3套配的情形,比方南家是1543牌型,有时候是一套配,对于这种3套牌的情形,无论几套配,都可以采用我设想方案:1h-2c-2d-3s这个3s就是hdc三套关键张问叫,可以更精准的问出3套牌的akq,哪怕没有满贯,因为非常低就开始问叫,肯定可以安全地停在5阶定约上,最后由问叫人问叫后确定最终是哪套配的定约。最终真的不一定就是红心或者方块定约,比如[hv=pc=n&s=sa6ha86dq9caqjt54&n=s4hqj742dak7532ck]133|200[/hv]就是7c/d的好牌。比如[hv=pc=n&s=s86ha74dq9caqjt53&n=s4hqj852dakt653ck]133|200[/hv]就是6d或者6c的好牌等等还有很多各种变化,都是基于一个前提----要问清楚cdh三门的akq和sa。没有了我设想的工具,现在估计只好4nt当成hd的双套关键张问叫,充满了冒叫的风险。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted September 23, 2013 Report Share Posted September 23, 2013 1、这个4♦不是三次低花木吗?--不是,虽然2♣已经建立了逼叫进程,但前期已经表示过红心的配合,相当于确立过将牌。 2、北家现在叫出4NT按两个红套的双套关键张问叫比较恰当。 Quote Link to comment Share on other sites More sharing options...
xhq Posted September 23, 2013 Author Report Share Posted September 23, 2013 这副牌在实战中好多牌手(北家)都叫4♥而结束叫牌,痛失6♥。我们抛开沙漏的延迟性加叫不谈,应叫人已经显示例了对开叫人两套牌的配合,且第一次应叫的是2♣,其♣K已经升值,配合产生赢墩,整手持牌已经升值。此时开叫人应该开始满贯尝试,开始扣叫程序或4NT关键张问叫。整手牌如下:[hv=pc=n&s=sa82hk74dq96cat32&w=skt93ht9dj85c7654&n=s4hqj865dakt432ck&e=sqj765ha32d7cqj98]399|300[/hv] Quote Link to comment Share on other sites More sharing options...
dvd Posted September 24, 2013 Report Share Posted September 24, 2013 3d后,南扣3s可能更合适。在北叫出至少55套后,不管南有没有支持过d,之后的关键张都建议使用双套回答。 Quote Link to comment Share on other sites More sharing options...
xuefeier Posted September 26, 2013 Report Share Posted September 26, 2013 但是北家并不知D有配合,回答出的关键张会不确定 Quote Link to comment Share on other sites More sharing options...
