发帖数: 3277 | 1 The jump rebid over partner's two over one game forcing shows a solid
suit and at least two controls outside the suit(which makes the hand slamish).

after 1S 2C,

SAKQTxxx HKxx Dxx Cx,

slightly better than 4S opening. It denies out side Aces.

If one does not have a failing memory, Namyats has its merit in such cases

Also after jump, I like to play rebidding partner's suit as showing a filler,

The structure is plausible. Be sure it fits your system.
I doubt this will work with your jumping rebid Axx xxx AKQJ10x x,
which is "enough" in your method. However, seems here the responder
has to bid 4D with a moderate hand. I just wonder how you are going
to manage to get 11 tricks in diamonds, comparing with the laid-down
9-trick 3NT, which can never be reached now. I hate useing artificial
examples. But sometime, it may help clearify the point.

I guess I'm a bit uncomfortable to be forced to 4D with holdings of more than
2 D. In many case with a minimum 3N is still the last train. So 3N just denies
a cuebid and slam interest (for the time being), and shows broken major
stoppers.
As to a hand like Axx xxx AKQJTx x, it's a very good hand, surely better than
your average 18 counts. I don't see a problem of rebidding 3D after 2C. With
above pd's hand, a bidding such as:

发帖数: 623 | 6 * Rebidding considerations
In many cases, what to open is dictated by rebidding
considerations.
This problem is especially obvious when you hold a 2-suiter,
while you expect to bid your 2nd suit on next turn, reality
often forbids you to do so.
Say, if you have S-C minimum to medium, and open 1S, you'll
be end-bid if partner responds 2D. You can't bid 3C and
rebidding S may be a distortion of your hand.
Generally if you have 2-majors or 2 minors you are less
concerned. If you have:

partner's 2C response, and raise 2D to 3D as a preempt as oppo rate to have at

stronger 2S (impossible S) rebid. If partner rebids 2H you pass. If partner
rebids 2N, you sign off 3D. If he reverses to 2S, my preference is to play

发帖数: 3277 | 8 the back bone of walsh style response is that the system allows opener

If you bid 1D, over pd's 1NT you would have no good rebid.
2S shows at least 4-5 distribution.
2C/2D are both sign off.

This problem is also somewhat system-related, if you have ways to sign off

发帖数: 295 | 10 As I remember, Hardy briefly mentioned signoff after reverse in his old book.
A 2NT or a simple rebid of his suit by responder shows no more than 9 hcp, and
any other rebid shows 9+ and game forcing. Therefore, 3D is the preferred call
here. 4D definitely claims a more distributional hand if no other
other special agreement between your partnership.
In this particular sequence, the responder have to rebid 3H with 5 hearts and
a minimium, not always a pleasant choice for you guys. Thus I suppose |

发帖数: 3277 | 11 the point is that for single suit strong hands,
you would always have rebidding problems if you open one level,

new suit forcing, not rebidding your own suit forcing.
So no matter how hard you try, you would always have rebidding problems.
You may argue that you can survive it. However, if you often jump to

For this particular hand, to pass 1S may be a good idea.
Generally, I think the 1NT rebid doesn't promise extras. The reason is that
he may not like to leave you in 1S while 1NT seems "right".
You may raise 2NT with the hand above.
Moreover, with 4243 or 4342 minimum, will you rebid 1S over 1H or 1NT?
if you always rebid 1S with 4 of them, then partner's 1NT cannot promise
any extras because he has no idea about your diamond length and thus even
can not make a "preference" in diamonds.

The logic is similiar to this one;
when you hold

if pd opens 1S, you can always raise him to 2S then later
rebid NT if possible to show your NT oriented hand.
but if you don't raise pd, you might not show your 3 card support

especially if the response is constructive, i.e, promises 2 of the 3 top

The idea is that there's a good chance that 2C opener has a long solid suit,
so the responder should often treat opener's rebid of suit as that. On the
other hand, strong 4-4-4-1 (or 5-4-3-1) hands are always the hardest to treat.
So after the constructive response, and opener's suit bid, generally

发帖数: 295 | 27 There's significant difference between 1C and 1D open.
1NT response to 1C is 8-10 HCP on many textbook. Because when you have a 5-7
balanced, you may bid 1D (sometimes with 3 diamonds) and then rebid 1NT,
if the auction continues. So here the 1NT rebid by responder is rather a
signoff.
when opening 1D, no room for this kind of maneuver and you don't like response
1H without real heart suit. Thus a 1NT response shows 5-9 Hcp and 2NT shows
10-12.
Now you can see only an immediate 1NT response to 1 |

One solution is to play 2C as either real C suit, gameforcing or

这种contract往往一干很多年，稳定性很强，有些几年有一次rebid，但是问题不大，
俺见过最长的一个，你猜多少年了? 27年！而且还没有结束的迹象。
DC周围这样的公司多如牛毛，大大小小，难的不是做出东西来，而是如何拿到合同，一
旦拿到，不是铁饭碗也绝对不是瓷的了。因此，熟悉政府合同运作/规范，专门给人写
竞标书的人收入非常之高。
这种合同和你以为的"正式大公司"没有什么不同，正式大公司也得找客户，签合同。只
不过这里的客户是最有钱，也最烧钱的政府而已，政府一年的IT投入吓死人。DC周围的
出名的几万人大公司，基本都是靠政府合同吃饭。 |

发帖数: 31 | 49 This is a hand I played in club last night, since my partner and I did not
have an agreement of the following bid after a reverse, it was bad.
My hand was :
S: AX
H: AJXX
D: A
C: KJT9XX
1C P 1S P
2H P 2S P
3C P 3N P
4C P P P
I thought we were playing lebonsol 2NT slow down, so his 2S shows a decent
hand. I rebid 3C, he bid 3N. I think I have a chance to make a slam, if he
has heart shortness and some clubs. I bid 4C and he passed.
Dummy comes down to:
S: KQXXX
D: X
D: JXXX
C: XXX
