发帖数: 2804 | 1 IMP，有对无，你拿到：32 / 5 / KJ97642 / AQ9
右手方第一家开叫2C，对方提示为精确法的开叫，至少五张梅花（如果只有五张，则还
承诺有个四张高花），10-15点。
你决定争叫2D，叫牌继续：
E S W N
2C 2D 2H P
3C 3D AP
2C = precision
2H = 建设性，但不逼叫
3D = 7张方块，牌型较好，决定多叫一口
左手家首攻C10，明手摊下的牌，better than what you deserve：
K854
AJ832
QT
52
32
5
KJ97642
AQ9
右手第一墩放小，你CQ吃到。接下去怎么打？ |

dummy. Ruffed by RHO with low trump? It is still fine. I must have missed
something, since I don't see the point of the post :)

发帖数: 642 | 6 Oops, I misread the bidding, thinking LHO bid clubs. That is why I thought
3D is very safe, and did not want to waste energy for overtrick.
Now I see the point of the post. Sorry, my bad!
I think the answer is to play low C after winning CQ, preparing to ruff CA
if opps don't clear trumps.
9

发帖数: 2804 | 8 其实打了一轮方块之后还有机会，庄家可以从明手拉梅花，手里放C9。之后如果对方吊
将，CA就是第九墩。如果对方不打将牌，就可以将吃CA。但是如果手里的小梅花不是C9
而是更小的牌，那这个打法就会有问题。
从技术层面上，CQ之后立刻回一张小梅花可以确保定约。实际分布是，西家有全部的四
张将牌，所以如果先打一轮方块，定约已经做不成了。实战中庄家不假思索地第二墩打
出CA，西家将吃，拔DA再继续王牌，定约宕一。作为考题来说，大家可能会多想一想，
但临场拔CA的牌手我估计是大有人在。

It is true this play may be likely missed at the table.

发帖数: 642 | 11 I see what you are talking about. But at the table, declarer is unlikely to
draw one round of trump, then play C. I did that because I misread the
bidding :)
Declarer will either try to cash CA, and if not ruffed, will score an
overtrick, but if ruffed, he will be down likely. Or if he notices the
danger, he will simply play low C at second round, giving up the possible
overtrick.

发帖数: 2804 | 15 How do we know C10 is singleton? If we do, then no one would cash CA at
trick 2, right? :-)
From the bidding, West can have 1, 2, or 3 clubs.
