How to avoid the disaster?

This hand occured at a world competition by BBO live broadcasts in June 4,2010.

Obviously,led H and downed one trick .So, how to find worthless doubleton and avoid a catastrophe?

----------------------------------------------------
Here,simplified and tradional chinese characters version


如何避免灾难?

这副牌出自2010年6月4日在BBO转播的一场世界比赛时的真实牌面:

很明显,首攻H,直接宕一墩。那么,如何发现双张小而避免灾难的发生呢?

我以前在哪看到过的,好像是伯根还是谁的定约,就是用于1NT后,应叫人在3阶叫单缺的!后来在中游,我看到鬼鬼紫和search x用过,但后来我找了半天也没找到出处!
如果用了这个定约的话,后面3阶叫3H,表示个什么的话,避免出问题,最后拉上4S,没问题!

在2c问高花保证一门高花的情况下,在2nt之后设计个叫品【有人设计好了吗?要什么约定叫呢 :) 】,3止张,3止张,同时所叫高花保证3张配合。
PD在所问高花有止张的情况下叫3NT;没有的情况下加叫到4阶打43配合的高花定约。[不会出现既对不上套也不会所问高花无止张的情况!]

那么上述叫牌进程将会是:
W N E S
P (P) 1NT (P)
2(P)2(P)
2NT(P)3(P)
4(P)P(P)

如果这里W不是S套而是H套,则必然有止张叫回3NT即可。

I don't agree that this is a catastrophe. E/W are getting a minus score unless they can somehow stop in 3.

At the point West bids 2NT, they may suspect that hearts are a weakness. But if 3NT does not make, how likely is it that 4 will make or that you can stop in a minor suit partscore at a makeable level? And in order to discover if this is possible, you will need an auction that reveals a lot of information to the opponents which will be very helpful to them whenever the hand is a normal 3NT contract.

970902介绍的约定叫与在哈代2/1中约定有矛盾,哈代2/1:1N 2C后应叫人再叫3H/3S是斯莫轮。表示逼局高花4/5或4/6套。
最好是不影响在哈代2/1中约定外找一个办法解决这类问题,否则就顾此失彼。
