The original question is:

after (1x)-Pa-(Pa)-1NT, do you play Stayman, Transfer, etc? What about Pa-(1x)-Pa-(Pa)-1NT?

Also, do you use the same range when balancing with 1NT over 1 of a minor than over 1 of a Major?

原来的问题是：



在 (1X) - 不叫 - （不叫） - 1NT之后，你还使用士台曼、转移叫吗？ 那么，在 不叫 - （1x) - 不叫 - (不叫） - 1NT之后呢？

另外，敌方开叫1阶低花或1阶高花，你作出1NT平衡叫的牌力范围是否有差别呢？

[yzdhy668]

平衡叫1NT，10~14点，均牌。当敌方开叫一副低花时，平衡叫1NT不需要在开叫花色中有止张；当敌方开叫一副高花时，平衡叫1NT需要在开叫花色中有止张；其原因是低花≥3张；高花≥5张，平衡1NT后的应叫同开叫1NT后的应叫。
敌方开叫一副低花，平衡位置15~16点，先加倍然后再叫1NT。
敌方开叫一副高花，平衡位置15~16点，直接叫1NT。
平衡位置直接叫2NT，不是“不寻常”2NT，表示均牌，≥18点。

平衡位置争叫1NT后，应叫手段可以和开叫一样处理，由于点力没有直接位置开叫或争叫强，叫牌需要谨慎些，切不可太冒

谢谢yzdhy668的解答使我对这样的叫牌进程更清晰了

[gamebridge]

平衡位置的 1NT 可以 system on,一切照旧。当然理论上来说,推进人当庄家也许更合适。

yzdhy668回答得很清楚了。不过看这段话，是不是原文作者就有一个结论性的东西？要不一并将原来的结论也译过来？

[shingkit]

好啊，原帖的楼主还没有再说话呢，不过原帖中有一些跟贴我觉得也值得看看。处理方法与哈代建议的不一样，不过好像也有一些道理。我贴在下面大家看看有没有道理。

Our choice is:

After balancing NT, no.
After strong NT overcall in sandwich position, no.

我们的选择是：

在平衡性1NT之后，不。
在sandwich位置（即敌方2家都叫过牌后）的强无将争叫，不。

In sandwich position there's a very good chance responder has a yarborough or close to it and would like to be able to get out in 2♣ or 2♦.

Not as sure about balancing position, but probably if you (direct over their 1-opening) have a decent hand with a five card suit you would have overcalled, so you either have a bad hand with a five card suit, or a bad or good balanced hand, or unbalanced but with their suit.

With a bad hand with a five card suit, it may be clubs or diamonds so you'd like to be able to play there. With the good or bad balanced hand or good or bad hand with their suit, you're either going to raise the notrumps or pass so there's no problem there. And with a good hand and a four card major (perhaps missing the other major so you couldn't make a takeout double) you can always make a cuebid.

在sandwich位置（即敌方均叫过牌后的位置），同伴很可能是一手白板牌或者所差无几，因此我们会希望能够叫到2♣或2♦。

不太清楚在平衡位置楼上aguahombre的考虑，但我想如果你坐在开叫人的下家，有一副不错的牌而且带有5张套，你是会盖叫的。因此，你要不持有一幅差的牌带有5张套，或者是一幅均型牌(无论好坏），又或者是非均型、持有对方套的牌。

对于持有一幅差的牌带有5张套，可能会是梅花或者方块，因此你会希望能叫到哪。对于均型牌(无论好坏），又或者是非均型、持有对方套的牌，你要么叫无将要么不叫，这不会有问题。对于一幅好牌带4张高花套（可能你没有另一门高花，因此你不能作出技术性加倍），你永远可以做出扣叫。

Liking Quantumcat's thoughts about sandwich NT overcall.

For Balancing 1NT overcall, we'd double rather than bid 1NT with both majors. So over 1 minor P-P-1N denies as good as 34 majors. We do not promise a stopper in their suit with balancing 1N. When holding 4=2 in majors over LHO's 1 Minor bid we bid 1N and parner can cuebid stayman to find 4-4 fit. No transfers allows us to play in 2 other minor. Not see much gain from transferring to 10-14 hand. (Think responding structure over opening 10-12 1NT).

Over 1 Major-P-P we double with 10-14/6 and 4 cards in the other major. 1N here denies 4-cards in the OM.

我喜欢Quantumcat 女士对于sandwich 无将盖叫的想法。

对于平衡位置的1NT盖叫，如果持有2个高花的话，我们会选择加倍而非1NT。因此在 1m-P-P-1N的进程中，我们否认有34高花。做出平衡位置的1NT盖叫时，我们不承诺在他们的花色里有止张。当在高花上持有4=2，我们会在左手敌方(LHO)的1阶低花上争叫1NT。同伴可以采用扣叫作为士台曼以便寻找4-4配合。我们不采用转移叫，这样我们可以停在2个低花定约。对于10-14点牌力的牌，看不到转移有多大的好处。（考虑以下对于 10-12 1NT的应答方式）

在1M-P-P之后，我们加倍表示10-14/6 以及另一个高花有4张套。这时候，1NT否认另一个高花有4张套。

还有一个回答挺有意思的。

After 1 ♦, ♥, ♠ openings or rebids and 1 NT from partner, I play 4 suit transfers, with transfer to their suit is stayman.
Over 1 ♣ 1NT pass I play system on.

The dwonside is: You cannot go out in 2 club.
Upside: You rightside many contracts and you make invitational bidding easier.

在1♦，1♥，1♠开叫或者再叫，然后同伴盖叫1NT之后，我采用4花色转移。对于转移到敌方花色的，这是士台曼。
在1♣后，同伴盖叫1NT, 敌方不叫，原来的系统还是适用的。

缺点是: 你将无法停在2♣
优点是：你将会在很多定约中找到好的做庄位置，而且你后续的邀叫比较容易

外国人的思路确实比我们精妙严谨，学习中...
