来自主题: Bridge版 - your bid
The reason why 4NT is designed as RKC for H, is because you could have set
up diamond as trump by bidding 4D first, but you don't have room to set up
hearts as trump (4H will not be forcing).
For me, the first principle is, if you have a chance to set up trump before
using 4NT, then 4NT is not RKC for that suit. For example 1H-4NT, that is
not RKC for me, since I could have made a forcing raise first, followed by
4NT. Similarly, 1H-1S-2D-4NT is quantitative (balanced 19-ish). I think 1H-
1S-3D-4... 阅读全帖

Yesterday, I played 1 hand.
I opened 1h, my partner answered with 2nt,
because my d is void, I bid 3d, he bid 4nt, I answered with 5d, he bid
5h, and I stopped. Finally, we found we had 6h.
Do you think 4nt is a good bid? I think, he should have shown his control
instead of bid 4nt. Because my d was possible to be void or singleton. 4nt
can't give us enough information.
Or maybe I just can go to 6h with my void d after his 5h?

三、BLACKWOOD and variations BW和变化
BW是用4NT问A的约定,此时它不可能是自然
意义的4NT,是问同伴有几个A。
答法:5C=0/4个A;5D=1个A;5H=2个A;5S=3个A。
再用5NT问有几个K。
答法:6C=0/4个K;6D=1个K;6H=2个K;6S=3个K。

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.

如果左手方没有PASS过,那肯定是不逼叫。但是对方PASS,后面第三家弱开叫,是不是
应该不同处理呢?
同样地,如果同伴没有PASS过,叫牌从右手开始,(2S) 4H (4S) 4NT,似乎应该是关键
张问叫。虽然有些牌可能会4NT是最佳定约,但是综合来说满贯试探的情形更多,4NT用
作问叫更合理。
但是如果同伴PASS过,也许4NT作为实叫最合理。一方面来说,同伴没有开叫牌力,满
贯的可能大大减少;另一方面,同伴任何5阶新花都是对红心定约的扣叫(不可能是独
立套前面却PASS),所以可以有别的手段探寻满贯。
不过,除非是很熟的搭档,弄得这么细大概意义不大,有一个笼统的约定就行了,已经
好过没有任何约定。
突然想到,叫牌的另一个可能是2S之后直接争叫3NT。但我担心的是,如果对方4S过来

Psyching is explicitly allowed by ACBL rules and you cannot do anything with
it. (their agreement of 3C was 2nd suit)
I did call the director after opener made another move after the slow 4NT. But
the opponents probably know that they'll lose the appeal so they did not admit
that there was a break in temp with 4NT. Since we cannot establish that fact,
the director ruled in their favor.

agree, 3NT is not good.
But he is not that strong for 4NT either, I think.
I will choose 3S if it is me.
4NT is not good too.
he could bid 6D directly after your 4C, hehe
But I also think your fault is same as your PD.
Think you have at least 55 Ds, you should change to 5D after 4NT
then you probably have no fault. if you PD stoped, it is his fault.

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

这副牌正常RKC没问题,但是很多其它的牌,4NT作为RKC太高,所以我们低花上从不用
4NT作为RKC,要么在特定的序列我们约定使用kickback,要么就不使用RKC,把4NT作为

That is perfectly fine in my opinion. But as you can see, both pd and opps
don't understand 4NT, so 1NT or 2NT would be even disastrous :)
My thought was that, if opps stayed at 3 level, I would let them play.

Passing 4NT won't be a disaster. I remember the blue team played un-doubled
1-1 5C, and won the hand :)
For serious partnership, I guess passing 4NT (only at this color) may mean
no preference for known two suits, and ask partner to bid his better suit
after double.

Without special agreement, 4H and 4NT may be explained differently.
If 4H shows limit raise by agreement, then 3H doesn't have to set up trump.
But apparently, this 4H consumes room for slam bidding. But at least this
design uses 4H bid, otherwise there is no meaningful 4H bid with this
sequence.
4NT RKC, without explicit trump, should assume the last bid suit as trump,
in this case it is D. The same principle is for 4C cue bid, which is for D,
rather than H. It seems confusing to treat 4C and 4... 阅读全帖

这个牌的关键需要明确对4H加倍的含义。这个加倍不可能既是指示首攻,又是建议加倍
。通常在专家级别的搭档中,由于前面缺乏低阶加入叫牌的可能性,并且是无局对有局

当然我赞成在叫4NT前先扣叫
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,

自然制是有点问题,对于这副牌。
2NT固然好于2C。2NT-3C-3S-4S后,是不是4NT问A还是有些把持
不定。南可以只有3-5点,照样支持4S。
1D开叫的毛病是非逼叫,可能被Pass。
2C毛病更大,2C-2NT后,简直没法办。出套要有5张,3NT肯定完

精确1C开叫,1C-1NT后,还可以2NT,然后南如3C(巴朗或斯台曼),

I guess a diamond lead works.
Pd could hardly be club void. coz that means opps have
9 clubs, i.e. LHO has 4 clubs at least. In this case,
he would have passed 5C or 6C most of the time.
It seems that RHO didn't take 4C as Ace asking, otherwise,
he should have passed 4NT. Therefore, 4S was a cuebid and he
took 4NT as Ace asking.
I guess the reason of LHO's hesitation is one Ace missing,
and he was thinking of taking chances that the missing ace was
not the crucial one.

the point is that

,同伴持低限时可以pass。还有一种“伯根约定叫”,把1H-3H作为0-6点的弱牌。这也

It's quite difficult to discuss system issues with you as it appears.
As I said again and again, the 4NT bidder doesn't say he holds SQ or not. So
we can only assume that he holds SQ about 50% of times. Then you just know
how bad your structure is for grand slam purpose. For example, suppose you
hold no SQ and two side kings, you still have to jump to 6S, which is simply
a very very bad bridge design, because if your partner holds trump queen,

2D = 双高花
2H = 方块加叫,limit raise or better
4NT = 黑木问叫
6C = 梅花长套,给同伴满贯花色的选择
问题来了:你首攻什么?

来自主题: Bridge版 - 怎么叫
那用我最心爱的人工系统海盗梅花试试:
北开叫:
1S - 1NT
2D - 2H
2NT - 3C
3S - 4C
4NT - 7H
1S = 11-15,5+S
1NT = GF
2D = 11-13, with 4+minor
2H = relay
2NT = 4D
3C = relay
3S = 5-3-4-1 shape
4C = RKC with S as trump
4NT = 2 key cards with SQ
7H = This is all I need. Even partner has no other side K, we can still
make 7 since dummy can ruff two clubs.
南开叫:
1C - 1S
1NT - 3D
3H - 4C
4H - 5D
7H
1C = 16+
1S = 5+S, 8+HP
1NT = relay
3D = 5S + 4D, 12+HCP
3H = relay
4C = 5-3-4-1 shape... 阅读全帖

4H/4S这里都是止叫,因为同伴都保证了至少4张。4NT是CRASH接力问Q,如果你想知道
同伴K的位置,就必须用4NT后面第一个可用叫品来询问。对这副牌而言是5C,注意5D/H
/S都是止叫。然后下一个可用的接力叫再来问Q。
详细的介绍看这里:

BBO上特别经常地看到以下两个序列被滥用,觉得有必要讨论一下。
假定叫牌如下,对手没有插叫:
(1)1NT - 2D - 2H - 4H
(2)1NT - 2D - 2H - 4NT
你认为应叫方大致是什么牌,最后叫品(4H或4NT)是什么含意?
希望大家踊跃勇敢地发表自己的想法,我们这个版面不能仅限于中高级以上牌手发言。
尤其是这类问题,我很想了解一下爱好者中的普遍认识。

The opp might get mad because you took his fun of 'declaring' away in the
pickup games (in Main?). I am sure he understood your 4nt bid, but got mad
when your pd passed (- now the 4nt bid was just for disrupting). I saw hosts
routinely kick out the psychic bidders.

一般说来是早叫为好,避免后期猜测。也许这是一把失配的牌,同伴手持4-1-2-6。就
算是4-1-3-5或4-2-2-5,也未必是个划算的牺牲。
另:unusual 1NT意义不大,在轻开叫和轻应叫盛行的今天,1NT有必要作为自然叫品。
又:理论上说,此时的4NT应该保证两个低花套。只有这种情况下你前期没法叫2NT(因
为那将是显示红心和方块),只能通过延迟的4NT来显示。

IMP 有对无。右手方开叫2H,你最终做庄6C。左手首攻H7:
AQ42
Q
AKQ2
AT92
K53
K543
6
KJ765
叫牌过程:
W S E N
2H P P X
P 3C P 4NT
P 5D P 6C
AP
3C 显示8-11点和梅花套
4NT = 关键张问叫
5D = 1 或 4 个关键张
叫牌有些粗糙,叫到缺HA和将牌Q的满贯。当然远不是hopeless,你只需要把将牌打对
就可以了。右手HA拿到第一墩,回HJ,你准备怎么做?
