这是实际比赛中的出现的一副牌,许多人多没有叫到最佳定约。假如你持如下的牌,同伴开叫2,你如何设计一个叫牌进程,叫到最佳定约?

2n=报短套!同伴答3c,问a,上6d,答3d,问a上6c!我不认为同伴有4张s!,当然!这办法很笨!

应该是正常的ogust2N即可。
开叫人不会持4张以上S,那必然在低花上有部分配合。那么可以的定约就在H/D/C上都有可能。
2N后,开叫人的叫品将是一个人工性的应答,然后四阶进行扣叫---4N问叫----然后确定定约。
对开叫人答出的好套/坏套,好牌/差牌如果有明确的定义就更容易一些了。

同意3楼分析,从2N开始,低花肯定有配合,叫出D/C套,让PD选择。

同伴只是开叫了二阶,红心就是6、7张,低花肯定有适度的配合,我会跳叫3,用沃尔什问叫展开叫牌。
最大的可能是叫到低花满贯。
