我的进程这样：
south north
1H 1S
2C 2D*
3D 4C
4D 4NT**
5H 6C
P

2d*=第4花色逼叫
4NT**=对草花的RKCB

I think ,I can not bid better then yours ,but 7♣ can try

[hopeoffire]

very hard to reach 7C when you are void in your pard's openning suit,6c is a good result, congratuations!

[AKQJ2008]

我觉得2D不如4C明确 正好能探知D的情况！既然用了4花逼叫 2H显然有问题 本手应该3nt的。最后也必须诚实回答问叫 在自己并不清楚所有牌情的时候更应该如此！尊重pd=增加信任

[Fluffy]

south should bid 2NT, not 2♥ since he has diamond stopper, 3♦ as yin suggest is also a good idea

north should never use blackwood, he has void so blackwood is useless.

south should answer blackwood, only reason no to answer blackwood is to have a void.

世界大师fluffy说：

南家应该叫2nt而非2♥ ，因为他有D的止张；yin建议的3D也是一个好主意。

北家绝不能使用黑木问叫，因为他有花色空门，所以黑木问叫是无用的。

而南家应该回答黑木问叫，如果不回答，原因只有一个，那就是有空门花色。

还有一个思路就是2c应叫起步，再黑桃逆叫，虽然只有11p但是牌的质量足够这样叫牌，关键是后期要拒绝同伴的3n,6c会很轻松叫道

[sleekrain]

2♥是绝对错误描述，♥不并无很多点，而♦有很好止张，通常2N也很精确描述你的牌型和牌点，1534或者是0544,♥不好，D有大牌点。同伴叫出3C4C就强烈满贯兴趣，不会担心你H点力浪费。

有高花总是先叫的。不会叫低花。
