Scoring: IMP

Playing 2/1. This is a laydown 7NT, but how to reach it?
After 1C-1H, what's the best rebid by opener? if you rebid 2NT, responder can use some checkback stayman to ask opener's majors, but he normally will not find your good 6 clubs. 3C, is that underbid? Do you have any special treatment for opener's hand type?

As a start ...

I rebid 3NT to show a hand too good for 3. This is either a 16-18 hcp hand with a seventh club or good 18s up with six clubs.

I have also been experimenting with a 3 rebid to show a standard 3 rebid but with three-card support for responder's suit.

I bid 3 to show this exact hand: 6+s with a 3 card support and maximum hand. This will help a lot!

EDIT: typo fixed :)

A typo? I think you mean you rebid 3's to show this hand, not 3s.

The auction is fairly easy using a jump to 3 as 6+, 3 card support, and a good hand.

1   1
3   3
3   3
4   4
4N   5
5N   7N
Pass

3 = six+, 3 very good hand
3 = nmf or new suit forcing
3 = waiting what else can I do, can't bid NT, no control, can bid 's
3 = cue-bid slam try, makes 3 a cue-bid now too
4N = key card blackwood,
5 = two key cards plus the heart queen
5NT = I am thinking grand slam, looking for an extra trick.
?

Your next bid over 5NT depends upon your style. You may cue-bid your king with one and bid grand with two. You may show your number of kings in steps. Etc. Here, I like to show my extra stuff. On this hand, I know my J is an extra trick, as is my K. And my J is probably very useful as partner was interested in K or Q, he would have bid 3NT over 3 to give me a chance to cue-bid either of those fitting cards. So regardless of how I normally respond, I think I would bid 7NT here.

If you don't play this jump to 3's shows this hand, you will have to invent a bid. Since 3 is wrong then if it denies support. 2NT is wrong for two reasons, this hand has a great source of tricks and you sort of have a problem. 3NT is about right on stregnth, but wrong on 's. So that leaves two possible bids, 2 the worse looking reverse in the history of bidding, or 4. Four here in theory should show a solid suit and four card support. So it it better to pretend that you have one more than you do and bid 4 or two more s and bid 2. Since AKx looks like better support to me than many 4 card suits, I believe I would pretend to have 4's and rebid 4.

Now the bidding is very easy...

1   1
4!  4NT
5   7N

4 = solid suit plus four (!) card support
4NT = RKCB
5 = 2 key cards, no Q
7NT = 6 (Jack clearly working), 4, 2, 1.

I just open the North hand 2 NT, I think the hand is too good for 3 rebid. But after auction you gave I will rebid 2, which will get you to GS.

Ben, i like your idea about jump rebid in here.
3:6+, 3 card support, and a good hand
4:a solid suit , 4 card support
I believe both these bids will be GF, but if you get a hand with 16-18pts, 6+, without support or 3 card support, you want to make a invitational bid (you will bid 3 in standard bidding system with such hand) , how do you handled it?

We would bid as follows
1C 1H
2D 2S.............2D = GF with C or natural reverse, 2S = relay, shows slam interest
4C 4D.............4D = demands cues
4H 4N..............4N = RKCB
5D 5H.............4D = 3, 5H = Q of C ask
6D 7N.............6D = "yes" and 2 extra Kings

First, the jump to 3!C is not GF, it is not even forcing. :-)

Second, what do I do with a good hand and clubs without 3 card fit for partner? I have two options. I open multi-2!D with, among other things, an ACOL 2 bid in a minor. So the monster hand without a fit is not here. We play 2 of "other minor" like Ron does, one round force, and may not have the other minor.

Often our 2 of the other minor is balanced 17 to 19, as we save our 1m-1M-2N for something other than a hand too good for 1NT opening. The opener promises a rebid unless responder rebids his suit or raises the first minor. So

1C-1H
2D-2H
3C

for instance would be the hand with lots of clubs without 3 card support.

I want to construct a biddding structure to handle a good hand with a long minor suit.

1)GF hands open 2;
2)almost GF hands, like 9-10 winning tricks, open multi-2 like Ben does;
3)1m-1M-3m: 3 card support, and a good hand with long minor;
4)1m-1M-4m: 4 card support, and a good hand with long minor;
5)1m-1M-3NT a good hand with solid minor suit, without fit, and unbid suit stopped;
6)1-1M-2: forcing, real reverse in or long suit without fit, just rebid your next round to show this kind of hand; But if the minor is , 1-1M-?, i have no minor reverse to be used. In Ben's post, it seems you still use 2 here as forcing and multi-meaning. Is that right? And anybody can help me to improve my structure?

Michael,

The method you have drawn up is exactly what I am doing now with Misho. I think there would not be too much controversy until you get to your item number 6,

In fact, we do play
1    1M
2

As 100% forcing, and does not promise a suit. For matchpoints this might be a bad option, because it means you can't play 2s when both partners are weakish with a club fit. In fact with a weak hand and &'s we don't even rebid 2's. We will instead, (consider this auction.. 1-1-?)...
1) raise partner with three card support (3-2-4-4 or 3-1-5-4)
2) rebid 1NT (with 1-3-5-4, and even 1-2-5-5)
3) rebid our first minor is if is "strong" enough five card suit or a six card suit (1-2-5-5; 2-1-5-5).

This has an effect of making our low level auction where the hand belongs in 2 of the other minor problematic. But it improves out slam and game auctions, and at imps, I would rather bid my hands that can be +920 or more better than my hands that can be +90. I think it was Kantar commenting on the difficulty in modern bridge to bid clubs naturally (stayman, drury, nmf, 1 strong and forcing, 3 bergen, etc), who said something like "we can't bid clubs naturally anymore, and soon we they will take away natural 's bids too". Lol, misho and I are rapidly approaching this stage. :-)

This new minor has helped us in another way, I think. As i said earlier, we save 1m-1M-2NT for something other than a balanced hand. That something other is really good hand with raise of partner's major. So, to show the balanced hands others jump to 2NT on, we use the new minor by the opener as forcing, and then rebid 2NT. By taking using an opener's jacoby 2NT (for lack of a better term), we can narrowly define 1m-1M-2M and 1m-1M-3M (jump to 2NT is stronger than the 3M raise). This puts us at a lower level for slam tries (2NT being lower than 3M), and gives us room to use our limit+ raise responses to separate responders mear game interest hands opposite a strong raise from his own slam interest hands.

As a final caveat, after 1-1, opener doesn't have the other minor to force on. We still use the jump to 2NT to show a monster raise of responders suit. But now we rebid 1NT not with the balanced 11-13 (or 11-14 if you play 15-17 NT), but rather 1NT would be the big hand (17-19). With the 11-13, we rebid 1 of a major. This might be a three card suit, and this bid is not forcing.

This last concept is fairly new, as we always played 1m-1x-1M as 100% forcing before. I know one hand will not be convincing, but here is one played in a recent team match (freee was no my team at the other table, and had an interesting auction over there too).

Scoring: IMP
West    Misho  East    Inquiry
Pass    1      Pass    1      
Pass    1      Pass    Pass    
Pass    


Note 1 and 1NT are the only contract NS can make, but 1 is easier to make than 1NT, and in fact, you can make 2 if you guess everything correctly (1 ruff, 2, 1, and 4), while in NT, you have to guess right to make. The correct bid with my hand is probably 1NT (to play) unless partner has hidden extra values, but what the heck, 1 worked out well for us.

At Free's table, he was west and his partner opened 1NT (14-16) (despite having only 13...) and when Free bid 2 (stayman) and his partner took the decision to pass (Free was a passed hand after all). EW can make 2 without problems.

It is an interesting question to ask what if responder doesn't have either K or J?

I think even without agreement it's clear cut to start everything from 2 "reverse". Rest will be easy because responder simply has too much.

BTW, I cannot read all the notations after several times of refreshment. What should I do?

Michael,

The method you have drawn up is exactly what I am doing now with Misho. I think there would not be too much controversy until you get to your item number 6,

We play point number 6, but there is a lot more system to it than just "bidding C to show this type of hand"

2• = GF, natural reverse or just long D (not fit-reverse). The 2D re bid can be made on a GF hand with excellent ♣. Responder can relay with 2 of the other Major, or make a descriptive bid.

1♣ 1♥
2D
Now
2M/3• = 5+ cards

2 other M = relay
Now 2N = D-• reverse, NT-oriented (3m sets suit)
3C=C-• reverse, suit-oriented (3• asks to bid shortness)
3 suit = 6+C with shortness
3N = 6+C, no shortness, 17-19
4C = 6+C, no shortness, 20-22, demands cues

"I think your system works perfect for ♣, but how do you deal with ♦ suit, do you have any similar treatment for ♦? "

No. Over 1D we play natural GF reverses. Also 1D 1? 2N = Gf; over this 3C is an artificial checkback, asking for 3 card support, and shortages.

Even at MP same bidding is normally better. I will quote Rumen's words about good players: "If you stop at good score (in our case 2), opps will balance and find their fit. So you no need "perfect" sign offs as well as weak major raises, better to play without giving them info about type of your hand if weak." For example opps can pass our 5-2 score, havindg 4-4 in , due to 4 and even we go down they probably have major score.

My new version of NTC 2.70 doesn't include anymore 2 way major raises, weak hands even with fit bid 1NT. I was witness how Kalin bid in vul! with xxx,KQxx,xxx,xxx over 1 opening 1NT!!! and they won score against expert opponents. There is a difference between "I like" and "I want to win" sometimes...

Spoiler
By the way, do you like we to agree Ron's scheme or similar one after our NMF by opener?
