防守有将定约的首攻,传统的规则严格禁止从A中低引。其背后的逻辑是,如果有人是单张 ,持A低引很可能损失一个赢墩。除此之外,如果庄家在这门花色上有大牌,低引可能让他便宜地吃到一墩。这条规则广泛适用,但例外情况在所难免。
最重要的例外情况是,敌方叫到满贯并且明手显示在一门花色有K,而你持有这门花色的A。低引将使庄家面临猜测而他多半会猜错。比如在下面这样一个叫牌进程中:

明手肯定有梅花第二轮控制,因为南家跳叫5要求北家有控制的情况下叫到满贯,而北家遵命而为。而且,北家肯定没有第一轮控制,因为他没有在3之后扣叫4.依据分析,西家应该在持双张、三张带A或者Q时首攻小。南家和北家的牌多半是这样:

4难道不是否认控制?

通常对手没有问ace的情况下,我还是倾向于ca首攻,也许对手还差一个a,比如缺少sa,甚至将牌a或者k.

是——能把庄家搞蒙。跳叫5H后要求同伴有C套第二轮控时叫到6,受启发。
