请解释最后叫品的含义

[lycier]

How would you understand the final bids in the following sequences, sans in-depth system discussion, playing 2/1 GF with a 26ish YO partner:

 

P P 1H 1S

2S X 3S

 

1D 1S X 2S

P P X P

2N

 

1D P 2S(weak) P

P X P P

XX

 

(if it matters, scoring is IMPs)

第一手

[hv=d=n&v=0&b=1&a=pp1h1s2sd3s]133|100[/hv]

 

第二手

[hv=d=n&v=0&b=1&a=1d1sd2sppdp2n]133|100[/hv]

 

第三手

[hv=d=n&v=0&b=1&a=1dp2sppdppr]133|100[/hv]

 

请解释一下上述进程中的最后叫品的含义。

抱歉，这道问题出自：BBO专家级桥牌论坛，的确是难为大家了。下面就是我与众不同的回复，目前看来专家们和世界高手和我的看法不一样。

 

 

1-A heart suit fit hasn't been identified at present,so 3♠ was western cuebid ,its meanings is to bid 3nt as a final contract if partner has a spade stopper or a control .

 

2-its meanings is to ask partner what's your first priority ? it is impossible for the opener to play 2nt as a final contract.

 

3-its meanings is that I Don't believe 2♠ can't be made with extra values!

 

1-目前♥是否配合尚未确立，此际的3♠就是西部式扣叫，要求有♠的止张或控制，叫出3nt作为最后定约。

2-2nt的含义是让同伴选择最优的花色！2nt绝不可能是欲作最后定约。

3-双加倍含义是：开叫人拥有额外牌力，XX=我不相信我们不能完成2♠定约！
