针对这副牌,我的意见是:

 

after double,I think that it was best for the west bid 2 was a non-forcing bid to show 4-6 distribution .

意思:在加倍后,西家最好叫出不逼叫的2以显示4-6分布,而不是加倍。

 

 

2 would show a much stronger hand for us.

意思:应叫2对我们而言表示牌力更强。

 

问题是,你愿意接受谁的意见?

其实还是有专家牌手完全支持我的论点,2不逼叫,表达牌型;而强牌论者也许内心认为这是逆叫吧。事实上,这牌西家是有竟叫到三阶的意愿与需求的。理由很简单,西家一般多能承受住同伴的三阶示选。

如北沒有技術性加倍,西2H 是表達牌型,北作技術性加倍後的處理是不一樣的。

这时候西的2不是逆叫(不是开叫方,争叫2限制了牌力),尤其是敌家双方都叫了牌。7-4双套牌理应进取些。

 

我不认为东应该再加倍。

 

就算東不再加倍,開叫者重叫2D 後絕對可以作平衡性加倍重開叫。表示梅花不配合,對其餘花色均支持。

 

道理就如以下叫牌一樣

 

1D - 2C - 2D - X

 

眾所周知這時的X 是C 沒配合,對紅心及黑桃有好支持,中等牌力。

 

叫3C 平衡是最差的應叫,萬1西只是持5張CLUB套的話。
