After transfer, it's often very important to know the exact shape
of opener's to decide how high and what suit to play. So it makes
sense to play 2NT as artificial gameforcing with balanced hands
or 4 card side suit.
With invitational hands, one can bid 2C then 2S later to show it.
1N 2H
2S 2N(asking)
3C: 4+ clubs, may or may not have support.
3D: asking
3H: 3-3-3-4 or 3+ spades + 4+ clubs+doubleton.
3S: asking
3N: 3-3-3-4.
4C:3-3-2-5 or 3-2-3-5.

So 2c then 2S doesnt guarantee 4 card hearts? what about xfer to heart suit?
If you have 5 card hearts and invitational hands, how to bid it?
1N 2D
2H 2N?
1N 2C
2S 3H?【 在 cozofu (但为君故) 的大作中提到: 】

老式的(其实也不老)转换方式
1NT-2D-->转换到2H
1NT-2H-->转换到2S
有一个死角,就是类似这样的牌

按照大路的方法,1NT以后你转换到2S,可2S过来以后你怎么办?再叫3C不够(3C逼
局),那只有扭曲地再叫2NT显示“5张S邀局”?那同伴要拿3张S回3S岂不已经到三阶了?
相反这种牌在不用转换的古老时期却容易得很,就用
1NT-2C-2D-2S显示这类“5张S邀局”。
“现代”的体系这个过程,1NT-2C-2D-2S,不是Garbage Stayman表示停叫,就是至
少5-4高花邀局的,所以“现代”的路数这样还保证另有4张H。
所以,解决之道就是干脆放弃“现代”的方法,回到从前。
那么既然“5张高花邀局”,已经可以用1NT-2C-2D-2M的方式表示,也就没有必要再
用1NT-2D-2H转换-2NT来显示“5张高花邀”了,因此2NT可以腾出来赋予另外的含义。
一些目前比较前卫的无将结构,比如Scanian NT(瑞典无将),KERI(克林格NT),都
已经将1NT-2阶转换-2M-2NT赋予新的含义。前者的1NT-2D-2H-

With H suit, you can use 1NT 2D 2H 2S to relay.
To invite, you can just bid 2NT over 2H.

I thought 2nt over 2h means got a weak h suit. If h suit
is strong, why not 3h invite?

If my 5 heart is strong, then even 5-2 fit should be enough
for 3nt, imho.

In short, yes, because most "modern" NT structure, have applied 1NT-2S as
balanced invitational hands (plus some sort of other hands). Therefore, you do
not really need 1NT-transfer to major-accept-2NT as "balanced invitation with
5-card major".
The real beauty of Keri is you can invite with 4/5-card major at 2-level.
You can't invite with Keri holding minors, but it can ben solved by including
such as in the 1NT-2S part.

This is one of my old article.
发信人: arrows (箭笑江湖), 信区: Bridge
标 题: 1NT 结构的小小改进
发信站: 瀚海星云 (Sat Mar 6 09:36:45 2004)
现在常见的1NT应叫结构中, 为4441的进局牌力设置了特定的
叫品。(2NT转移草花,再叫表示单张)个人认为其效率不高,
因为这种牌出现几率低,即使真的碰上,也完全可以简化并入
到其他叫牌进程中。
另外,在常见的1NT应叫结构中,似乎对低花单套满贯兴趣的
牌和均型满贯兴趣的牌没有明确的叫牌处理。
所以我建议,在保持原有骨架的基础上,对此作点改进。
司台曼和转移高花照旧,3阶的应叫也照旧:3C、3D自然邀叫,
3H、3S我个人比较喜欢自然单套,满贯兴趣。
2S:询问牌力。开叫方如果不准备接受成局邀请就叫2NT,如
果持高限牌就在低花中作出示选。此后应叫方的再叫:

PASS:止叫.
3C: 双低花的示弱叫。
3D: 方块套的示弱叫。
3M: 自然4张套,一般否认其他5张套,否认对另一高花
