几点说明:

一、假设你和同伴（指叫牌练习中的同伴，以下同）以及对手均使用规范的SAYC体系以及常用的约定叫。如果你认为基于其它体系或某个特殊约定叫的叫品更好，解答时请说明该体系或约定叫，并请给出以下两种解答：
1）基于规范的SAYC体系以及常用的约定叫的解答；
2）基于其它体系或某个特殊约定叫的解答。

二、假设你的同伴是个叫牌严谨准确、值得信赖的专家级牌手，并且你们是第一次合作。请勿认为这个同伴就是你的多年老搭档（尽管你的多年老搭档可能是Benito Garozzo）。如果你认为你和你的多年老搭档使用的特殊体系或特殊约定叫更好，请说明并给出以下两种解答：
1）你和陌生的搭档合作时会使用的叫品；
2）你和你的多年老搭档合作时会使用的叫品。

三、假设对手是头脑清醒、正常叫牌的高手。答题时，请勿先假设对手已经叫错了牌。
