来自主题: Bridge版 - 5NT问K
如果以5NT问K,那么问的意义就在于保证A齐有小满贯的前提下寻找大满贯;而有的问叫
系统,比如Gerber 或 Kickback,问K不一定是以大满贯为目标,也有可能是探索小满
贯或者选择好的满贯花色。A不齐也可以问K,K齐了也能做小满贯。这在一些精确类体系
中有时会遇到。
当然,大多数情况下,关于K的位置信息要比总个数重要一些。

3H不可能是寻求3NT,否则无法解释2D.
所以3H表示比叫4S更好的牌。
因此3NT不是自然叫, 应该是serious满贯兴趣,
看刘京的牌, 基本上是纯粹的高限,3NT应该不错。
李杰4S至少少叫了一墩牌:比较一下这3手牌,就知道区别了:
1. S AKQx H xx D Axxx C xxx
2. S AKQxx H xx D Axx C xxx
3. S AKQxxx H xx D Ax C xxx
在同伴2S之后:
牌1. 4S, 牌2. 扣3H,再4S。 牌3. 扣3H, 再扣4D。
尤其是在同伴3NT响应之后,没有任何理由不主动进满贯,
4D,同伴4H,下面RKCB,接着5NT,刘京CAKQxx,当然7S。
不管后面他们后面发生了什么误会,就整个叫牌进程而言,李杰

Jie didn't cue 4D then 4NT, took the charge.
Perhaps it's a good idea to do your homework, reading their convention card,
before putting words in their mouth. After 2C open, 2NT 3C 3D 3H 3S are all
simply invitations. 2D starts GF sequence. These are just the FACTS,
nothing to argue about.

~~~4NT. 5D guarranted. If North responsed with 5H/S, then 6D.
~~~Absolutely 4NT. Since North has shown strong in S with
no less than 15pts. no reason to reject 6-2 trump for a slam.

6C or 5NT. I use direct 5NT as a full slam invitation. If pard has
top controllers of the suit he has bid, and strong trump support(any

I think it is.
Well, first it is not force to grand.
And you didn't show any thing about yourself yet.
If you have spade, then why not just 5NT or 4NT instead of 2NT?
So I guess, After all 2NT and the following blah blah,
if you bid higher than 4NT now, it is unlikely to reach GRAND.
However, it is easy to stop at 4NT which you don't like.
A 31-35 range with solid heart is good enough for slam, I think.
That is why I prefer 5NT than 4NT, you need to give you PD a little more
energy.

来自主题: Bridge版 - how to ask for trump Q + side king ?
As I understand, the most popular treatment is:
After RKCB, the cheapest non-trump suit bid is
asking for trump Queen.The answer is:
1. without trump Queen, bid the trump suit at the lowest level.
2, with trump Queen, bid the trump suit at the next level.
3. with trump Queen and side King(s), bid the suit you have the
King up the line,with 5NT showing a "unbiddable" side King.
(if there's no unbiddable kings, you may use 5NT show 2 side Kings)

就这手叫牌,两方面都显出缺乏经验。作为同伴,迟疑的时机不对,如果要思考,应该
在叫4NT/5NT之前,就把后续的叫牌想清楚,这时候用多长时间都没关系。而作为东家

4D:一个A
4H:接力问K
5C:加三级表示同色两个K,南现在知道同伴是SK+CK
5H:接力问Q
5S:0或3个Q,在5阶上的问叫采用031422三级答叫方式。南现在知道同伴一定是3个Q,
因为如果没有Q,北的牌不够1NT开叫。
5NT:超级接力问缺的Q的位置
6C:加一级表示缺的是最短套的Q,这里是DQ
7NT:同伴的牌是KQXX,AQX,XX,KQXX。7NT和7S,7C的机会均等。
看起来接力体系在处理某些牌上还是有优势的。

The basic idea is very simple here. Liu Jing sometimes may not really need
trump Q at all, because he may hold trump Q. In that case, side suit kings
are very important. So 5NT should be reserved for that purpose to preserve
space for cuebids. Therefore, a direct 6S has to show trump Q and no side
kings. Actually, in early days, some players do play a direct jump to trump
suit to show that hand type after trump Q asking. 5NT to show trump and no
side king allows you to cuebid side queens, which ... 阅读全帖

Let me make it clear, the whole bidding sequence doesn't make much sense.
After 2C, suppose 2C p 2D 2H 2S p 3C is nonforcing. 3H can be the only gf
bid.
So 3NT is to play, not serious or nonserious slam try, because if 3H shows a
gf spade raise, then you bid 3NT to show some serious slam interest,
partner bids 4S to sign off, there is no way for you to bid 4NT, because you
should just bid 4NT right away in that case.
Now after a natural 3NT, 4S shows mild slam interest in S. 4NT is RKC, 5D

3H = Splinter, 4张方块支持。而且我绝对不会拿单张HK去做splinter。
3S = 扣叫。应该没有疑问,不会是想打S定约。否则前一轮绝对不应该叫2D。
4C = 扣叫。
4NT = RKC
5H = 2 Key Cards (DK + CA)
5NT = 问K。
6H = 2个K,但绝对不会有HK。有人可能不会同意我,但这就是我的风格。

no reason for them to feel that they have to swing. This is not barometer
game, they had no idea that they were behind by 4 imps. They could easily
lead by 4 imps instead, and only need to push the board. It is possible that
they had misunderstanding over the 5NT bid.

来自主题: Bridge版 - 加倍的大满贯---一线生机
对于5NT的答叫,比较标准的是回答最低级的K,而不是K的数目。因为第一轮控制已经
都齐了,剩下的问题是能否拿到13墩,有时候某张特定的K,价值远超过其它的K。
比方这副牌,对5NT问叫,应该回答6D,表示有DK(否定有CK,但不排除有HK)。如果
问叫方感兴趣的是HK,可以继续叫6H,意思为:如果你有HK的话就叫进7,否则就停在6
上。

不过, 如果你用Roman Key card Black wood, 你也可以把你的缺门显示出来
5NT= 2 Key cards and 1 void
6阶花色,1 or 3 Key cards , 这们花色是缺门
6阶将牌花色,1 or 3 key cards, 有一门级别高过将牌的花色是缺门
然后事情就容易了
另外就算用Black wood在这种情形下,可能依然应考虑叫6个,因为你搭档的牌肯定相当好,

LOL, I should learn bidding from arrowhits :-)
But 4NT/5NT is convention (when not used as Blackwood). My opinion is: if I
use a convention in my bidding, I will always follow that, otherwise, my pd
will get confused.
Since I never have consistent pard, I never have chance to practice fancy
conventions. Like that 4D, I think different player will interpret it in
different way. If I use it, I am not sure whether my PD will understand.

it's rather straightforward,
1N 2D
2H 3C
after that, if partner can bid 3H, you'd bid 3S which is a cuebid.
if partner cuebids 3D/S which shows some sort of club support, you'd
cuebid the other unbid suit as a slam try as well. Then you'd
check key cards to decide which slam to bid. If partner bids 3NT
over 3C, you want to bid 5NT to ask partner to pick a slam.

1)
在4S和pass之间犹豫不决。局况仿佛倾向4S,因为对方的4H可以是很烂的牌在
加叫。本着相信同伴的原则我还是选择4S。同伴的牌很可能是
AKxxx / xxx / KQx / Kx
黑心4-1分布的时候打起来是很不舒服,虽然也不是全无可能。。恩,我又想pass了。
但是同伴也可能抓
AKxxx / xx / AQx / Kxx
6S都做得成!

2)x然后2H。这牌直接叫2H太强了些。当然如果叫牌进程到了
E  S  W  N

1S  x P 2D
P 2H P 3C
P ?
可能会有点不好决定。我一般是:when in doubt, go 3NT. 


3)3D叫一口是明显的六张套,同伴可以改3H。这牌就算不是MP我也不会让对方打3C的
啦。

4)修正理解。同伴是强pass,我的AQ坐在高点力后面通通升值,那我应该叫5NT让同伴选择一个slam。

5)选择是加倍或者1NT。前者表示了红心,

No, it doesn't make sense. You tell partner you had 4 kc, he bids 6, that's
the end of it, period. If your side has all kc, partner is supposed to bid
5NT just in case. If a grand slam is missed because partner jumps to 6
prematurely, you win the postmortem.
For this particular hand, even if partner has HA, don't you still need CK or
DK to make 7?

那IMP怎么翻译?国际序分?
这个牌跟局况还是有点关系的。如果对方单有,2C应该是个好套,同伴有梅花废点的可
能性减低,这时候就可以5C问叫,如果同伴有3个关键张,还可以5NT继续问K,如果同
伴有SAK/HA/DK,基本上7S应该是铁牌。

6S is the only correct bid. It's Liu Jing's problem.
Here, 5NT show 3 KC, no trump Q. 6 level new suits shows trmp Q and K in
that suit. 6S shows trump Q and no side K.

why 5NT denies trump Q is a better treatment
than using 6S denies trump Q?
For me, it's just counter-intuitive.
