1、加级表示14、03个关键张，就是4NT后，5C表示的是14个关键张，而5D表示的是03个！
2、碰到干扰，用dopi

——现在问题来了，现在我们4NT开问后，人家5C干扰，我加倍，表示的是几个关键张啊？或者你认为该是几个关键张呢？

1. 照字面的約定 - D0P1: X = 0, Pass = 1

2. X = 1st step (i.e. 1/4), Pass = 2nd step (i.e. 0/3)

——所以，dopi的设计，我以为根本就不是什么加级的颠倒的问题，而是纯粹的为冲击满贯的取舍而准备！

u19,现在理解了，遗憾的事情多着是，你看一般人就连起码的打牌规矩和礼仪都做不到，还说啥啊。除了我之外我就几乎没见过哪位群主宣传桥牌礼仪和起码规则的，原因很简单，就是不懂也不知道......
