这次的题目考验你和同伴之间的默契。
IMP双有，你坐南拿到：72 / AT8642 / KQ4 / 92
同伴第一家开叫，叫牌过程如下：
N E S W
3NT X 4C P
P 4S P P
X AP
3NT = 赌博性，一门坚强低花套（至少7张），旁门无A/K
4C = 逃叫，pass or correct
第一个问题：你首攻什么？ |

发帖数: 20570 | 3 This is a lead directing double. Partner must hold a void in H. So it is
normal to just least H8 to ask for a ruff and suggest a D return.

发帖数: 642 | 6 Yes. The only reason pd can double is void. H is much more likely than D.
Just curious for the H8. Do you worry HT can be costly, or do you think DKQ
is not as strong as DAQ to play HT?

这副牌，同伴已经显示了一个坚强低花长套，边花没有控制，因此不可能是凭实力加倍
，所以加倍一定是Lightner double，有一个缺门。从手中牌来看，极大可能是红心。
首攻H8或H10是个好的想法。H10在某些情况下可能会损墩，但一般说来问题不大。实战
中首攻方选择HA，明手摊下：
Q93
9753
JT9
654
你自己手中的牌再列一下：
72
AT8642
KQ4
92
同伴果然缺门，垫C10。接下去你出哪张牌？

发帖数: 20570 | 8 Partner may take HT as a lead from sequence like T9xxx QT9xx.
With DAQ, you can usually lead HA and HT, because you have quick entry to
give partner another ruff.
Therefore, H8 usually should suggest interest in D.

发帖数: 642 | 9 If 3NT is strictly a solid suit, CT would be likely to suggest AKQJT holding
. If this is true, we return H2 to ask pd to under-lead C. This will get an
extra ruff. But I am satisfied with -2 for IMP, and I don't like the risk
and possible argument with pd afterwards :) So I would simply play H8,
asking for D return.

发帖数: 20570 | 10 one interesting point is that if you have shown AKQxxxx in bidding. You can
later pitch J to show AKQJxxx, T to show AKQJTxx, 9 to show AKQJT9x. This
certainly requires partnership agreements.

发帖数: 2804 | 11 Good defense.
Partner holds:
84 / -- / 8753 / AKQJT83
If partner returns low club after heart ruff, you take C9 and give another
heart ruff (return H8), partner then return a diamond to prevent you from
being end-played. Down 3.
Returning H8 at trick 2 will ensure -2, and prevents accident.
To get maximum tricks for the defender side, it needs thoughtful signalling
and absolute partnership trust. But the most important part is to read
partner's double correctly.
Another interesting question is what should partner do if you do return H2
at trick 2. Does it suggest entry such as C9, or may it be just a small
stiff? With the later case, partner needs to play CA and another club to
give you a ruff.
