2表示至少有一个A或K,或者有两个Q以上的正应叫,3NT表示没有A可扣叫,最后没叫到贯。

在另一个房间的叫牌如下:

--P-P-2

X-P-2-3

P-3NT-P-4

P-4-P-6

P-P-P

请问:叫到6对吗,在你的下家加倍2,表明K不能飞到,又缺A的情况下。可以看到,6是能MAKE的。

我觉得用Walsh Asking Bid ,查探梅花和红心的控制,并且冒险一点的话,好像可以?

 

Pass 2

2 3

3NT 4

4 4

4 5

6 6

 

======

 

3NT= 没有A

4 = Walsh Asking bid 问梅花控制

4 = 第一步,表示没有控制

4 = 问红心控制

4 = 第一步,表示没有第一二轮控制

5 =问第三轮控制

6 =第三步,表示有Q带头的第三轮控制。如果没有第三轮控制,叫5,然后AP.
