lycier Posted June 22, 2013 Report Share Posted June 22, 2013 记得美国桥协麦老师讲过类似牌面,她说:直接位2nt=15-18hcp,平衡位2nt=16-18hcp。所以,这牌我愿意叫2nt。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted June 22, 2013 Author Report Share Posted June 22, 2013 实战的四个叫牌进程如下:1、[hv=d=s&v=e&b=3&a=2hpp2np3d3hppp]133|100[/hv]结果:3HS-2,100,33.33%(东西方)2、[hv=d=s&v=e&b=3&a=pp3cdp3dp3nppp]133|100[/hv]结果:首攻C,3NE-2,-200,0%(东西方)3、[hv=d=s&v=e&b=3&a=pp3cdp3dppp]133|100[/hv]结果:3DW+2,150,66.67% (东西方)4、[hv=d=s&v=e&b=3&a=p2d3c3nppp]133|100[/hv]结果:首攻H,3NE+3,690,100%(东西方) 四个进程,无一例外的做了高阶开叫。从东西方最后得分的角度看:进程1南家开2♥,结果东家争叫后,位于3/4;进程2和进程3,北家开叫了3♣,结果东家都选择加倍,不同的是西家叫3♦后,东的最终叫品不同,导致结果分别位于4/4和2/4;进程4西家开叫了2♦,北家争叫3♣,同伴东家直接3NT得到了定约。位于1/4.

madongjun Posted June 22, 2013 Author Report Share Posted June 22, 2013 进程2和进程4,两个3NT,结果迥异,看来是相信同伴的3♣叫牌还是相信对方的3N叫牌,这是一个问题。四手牌如下:[hv=pc=n&s=sj76hq98542da8c87&w=sa43hj3dqj9753c63&n=st85ht7d42caqj542&e=skq92hak6dkt6ckt9]399|300[/hv] Quote Link to comment Share on other sites More sharing options...
madongjun Posted June 22, 2013 Author Report Share Posted June 22, 2013 我是第一个进程,是唯一持这样的牌,南家开叫2♥的。我得到了33.33%的比赛分。 请大家对四个进程讨论:哪个更合理?有没有考虑双人赛策略?如何应对高阶开叫? Quote Link to comment Share on other sites More sharing options...
