hzc111 ---

Never mind that I am a straight man. I have no doubt about your moral standard just like I don't suspect that Zhu, Fm Chen and Weir are all fantastic players. Forget the contest last time, we did not bad as a whole. Everybody may make mistakes now and then. Sometimes I just can't help myself from being a stupid player making basic errors when I am not in good mood. This is why I keep stressing event oriented, not necessarily people though. Don't you think everybody will feel more comfortable in this way ?

We all love bridge game, and everybody is just so gentle and nice with each other. You are always welcome to be part of the family.

hzc111，不必多虑，不要“In bad mood”啦。看得出你对桥牌的热情与认真，而且对牌理的掌握有足够的深度，也具幽默感。也正因此，我们由桥牌聚在一起玩，大家都很开心。且这是一个自发的，松散的但绝对是友好的（或说Nice的）团体，老友新朋都是“牌友”，还望继续发表你的“牌情”，时间关系，不敲打了……
向一直在作自我批评的老鞋同志学习！

canusa:

thank you for your response, but i don't agree with your interpretation of stayman convention.

in stayman 2c no need with 2 suits of major, and jacoby transfer must be 5 cards more in that suit.

bye the way, did we meet each other before?

iebuz:

thank you too. your opinion is the same as mine before. if we use gerber for slam approach, we can
leave the chance of 4nt for quantitative. its important we should make sense that nt opening
only gerber for ace asking. but if club is agreed
trump, something should be changed.

my question seems simple and common, but different
reply shows its necessary to unify our bidding system.

anything else more will be very welcome

I have not played Bridge for about 10 years so I may not remember the rules correctly. I think what you said is right. But I can still remember that there are several different commonly used Stayman rules including Stayman Convention, Checkback Stayman, Minor Suit Stayman, New Minor Forcing, and Smolen, etc.. Different players may use different rules. What you said is probably
Stayman Convention which is most commonly used by bridge beginners but I really don't like it because the responder has to bid 3NT in case of the lack of a fit. For the Jacoby Transfer, you may be partially right. There are also several commonly used Jacoby rules which are called Jacoby Transfer, Advanced Jacoby, and Accept Jacoby. Among the three Jacoby rules, Jacoby Transfer is the most commonly used rule which does not require a 5 card suit in hand.What you said should be Advanced Jacoby which does require a 5 card suit in hand. Anyway, I believe you are a very good bridge player and I wish I could have a chance to play with you together and learn more bridge skills from you.

Laoxi所言极是！桥牌中许多看似简单的东西，真能处理得当运用自如，也不是三两日之功。就这个例子的叫品来说，我以为最主要是看同伴间的约定（不论体系）。4NT至少是表达了对满贯的极大兴趣，且所持牌型及点力未知（是可以有一较为坚强的低花长套的）。邀叫，定约最终为无将，牌情暴露较少（也是规则容许的），但同伴可不叫，故为非逼叫性的；问叫，则为逼叫性，应是H至少4-4配，问什么由各自约定。用克勃森问叫，为将牌问叫（本人曾使用过）。还有控制问叫，点力问叫，但黑木问A似乎不妥，正如诸位所言，4C问A较好。那么问叫后的最终定约应是H有将定约，且几阶满贯须由问方决定。
感觉这样叫牌需要同伴间非常默契，并看什么场合使用。因为交流空间已不多了，会不会造成“猜测”，碰碰运气？LAOXI，牌例没说明何体系，应是自然了。实战中此类情况往往多出现于双人赛中吧。

Sat T storm, anybody would like to go to LeMirage ?

Below are some widely accepted convention used after 1NT opening:;;;;

1N-4C  Gerber.  Gerber is used only directly after NT opening or NT after a forcing open. 4C after a transfer or Stayman will be a cuebid

1N-2C-2H-4N quantative, implying H no fit. If H fit, you have to roll over second suit within 2S-3D or cuebid within 3S-4D.

1N-2D(!)-2H-4N, quantative

1N-4D(!)-4H-4N, Blackwood or RKC. That distinguish Texas Transfer and Jacoby

1N-4D-4H-P---  No slam interest.Sometimes it may be preemptive in nature.

However  1N-2D(!)-2H-4H, shows a good hand with slight slam interest, if NT opener has good fit and control, he can preceed to RKC(4N) or invitation(5H).

Same rule applies to S suit.

Goodluck to all you guys

To Weir:

I agree with your recounting. I wonder if we have chance to use Blackwood or RKC to approach slam after H fit. (4C is cue bid, 4Nt is quantitative)

Thanks

To Laoxi,

By convention, Gerber is only used directly after NT opening, or in the situation of 2C-2D-2N-4C, where 2D is a game forcing waiting bid, or 2C-2N-4C, where 2N is showing a balance hand with certain HCP. Gerber will never be used in the situation where a suit or a suit preference has been on the table-- If you do use 4C for ACE asking, you have to have partnership agreement beforehand. But this kind of 4C is not Gerber any more.

As in your situation, when you find H fit, I think it is better for you to cuebid or present second suit before proceeing to 4NT. It will make things clear.

If a second suit is presented after reply for Stayman, usually it implies the first suit fit. If PD(NT opener) raises the second suit with another 4 card support, the following RKC 4NT will have 6 keycards and 2 critical Q.

There are some exceptions, for example, the following sequence usually implies H unfit:
1N-2C-2H-3D-3N-4D. This 4D bid is still game forcing, usually showing a hand of 4-s and 5/6-D with good HCP for slam try. In this occasion, PD must agree on how to proceed. My agreement was: 4N showing no 3-d fit, 4S showing 3-d raise with 3-s and 4H showing 3-d with 2-S. The follwing 4NT will be RKC, being D as trump.

Anyway, this kind of occasion is rare, so there is no need to discuss or dispute between random partners.
