发帖数: 2804 | 3 第三轮为什么要忍ＨＫ？本来已经稳成了。
另：ＭＰ还是ＩＭＰ？ | j*******e
发帖数: 2168 | 4 对啊，不忍HK的话允许送2H树1H.
不过现在这几轮打下来，我们能不能假设LHO有5张D和HQ？可以的话应该还是稳成。三
轮S后，如果发现RHO4张S，vv的打法是成立的；如果LHO4张，那么拔HA看看HQ是否跌落
，没有的话LHO最多一张C，C就稳拿3墩。

发帖数: 2168 | 7 你是说，RHO有4张S的情况？垫1S1H，然后。。。没法垫。。。
但是，你得先告须我LHO在第3张S上垫了什么。。。
若是D就OK了；若是C，就CKA后D投入；若是H，就拔HA然后弄H吧。

发帖数: 2804 | 12 I expect this line to work most of the time. But still, it feels a bit
committal. Not only does it fail with 2254 shape from LHO, it is also
possible that LHO starts with 4-card diamonds after all, say 2344 shape.
This is annoying, if you are certain of his shape, you can always make. But
if you guess the shape wrong, you will go down.
Much better to take HK with HA at trick 3, you are guaranteed for 9 tricks,
highly likely 10.

发帖数: 2804 | 13 She already answered right? Play Dx to throw in LHO, hoping for 2353 shape.
I think this is very likely to succeed. You have shown 5 hearts and a strong
hand, the only sensible reason for LHO to play HK earlier, is that he has
something like HKQT (and even then, this is a bad play since it loses tempo).

如果不是3-3
1. 假如右边4张，打草花A双方都跟（假设），DA，假如都跟出，Dx，假设左手赢进，兑现完D之后必须打出H or C，
成。
2. 假如左边四张，打CA DA Dx 左手赢进，左手如果是4-3-4-2，这时被投入。左手如果4-2-5-2，后悔自己忍让HK

发帖数: 3714 | 18 It makes no sense for LHO to attack with HK if he had only two hearts headed
by K. Therefore it makes sense to play CA and finesse CJ if LHO turned out
with 4 spades (without knowing exactly how many diamonds he has), for
percentage play.

发帖数: 524 | 21 Yeah, is that right?
so after LHO pitch a club on the 3rd round of spade,
have to cash club K before going to dummy's Ace.
If both follow clubs, still have better
chance don't rush to play ace and another diamond.
For example, you may decide to watch RHO's discard on
DA, if it's a heart, maybe go with the threw-in, since
it's unlikely from 4 hearts holding. if it's a club,
you might just play HA and exit with the spade.
However, you may still guess wrong in either case.

发帖数: 2804 | 22 When LHO has 2353, 2443 shapes, or 2344 with CQ, it doesn't matter whether
you cash DA first or not. You can make either way.
If LHO has 2254 with CQ, playing small D is indeed better. If LHO cashes CQ
and exit with another D, you still have to guess whether LHO started with
HKQ or HKx (both cases are very unlikely, but I'll go with KQ tight), but it
is certainly better than 100% down as in the case of cashing DA then Dx.
However, what if LHO doesn't cash CQ? He simply exit with another D, can y
