右家Kit Woolsey第二家开1D，我们跳2S，左家叫3H，同伴不叫，Woolsey叫3NT结束叫

我相信仔细考虑的话，黑心Q首攻肯定是最优的；我们攻黑心Q，明手摊下：

在黑心Q下，同伴跟6（UDCA），庄家跟5。我们如何继续？ | c*****u

发帖数: 3277 | 3 if partner doesn't hold HK, you are mostlikely dead meat, cause
declarer holds 6H, 1C for sure, and most likely another trick in minor
suit and SK. So you should make your plan based on partner's HK.
In that case, if declarer holds SKxx, he's quite hopeless, unless he
has a lot of diamonds himself, for example:
Kxx x AQJxxx KQx, in this case, he gets 5D +3C+1H, so winning defence
is to switch to H.
Partner's first spade should be a counting signal, but you still don't know
how many spades he hol

发帖数: 2804 | 4 转攻红心肯定是不对，即使是下面的牌，同伴HK之后回S仍然不宕（我方只可拿三墩黑桃一墩红心）。转攻梅花应该是本手，基本上保留了所有的选择，只要同伴有CK和HK，或是HK和三张黑桃，或是HK和CQT,都可以打宕。转攻方块需要同伴有HK和DQ，可能是对的，但是纯概率上讲，不如转攻梅花的机会大。

But only C return will beat it, and for a strange reason.
On the surface, declarer only has 2C, 5H, 1D, so need another D and it does
not seem to matter whether to return C or H.
But say you return a H, and pd won the HK, and return the S, you won the 8.
You can't cash S as that gives the 9th trick. So you exit passively say with
a C. Declarer can win the A in dummy, and cash all the H, In the end game
his own hand is

发帖数: 18 | 6 最后被投入或则被敲下，欠缺周详的考虑，既然是这样设想的牌，就该再试一下转c会
是何种情形，自认为回h就可宕，根本没想过。：）
不过我还是不太明白既然不是s76,为何跟s6,这里显然不会是态度信号，只能是张数或
则要求转攻的信号。是否跟s3更合适？
