I would open 2. Should be easy to get to 6 after that, but 7 might be a problem.

The alternative route:

1 1
2 3
4NT 5
5NT ??

3 = forcing (2NT + diamonds would be NF)
5NT = any extras for the bidding?

Now it kind of depends on North.. if inspired, he'll bid 7. Otherwise just 6.

Tough one. I would treat the South hand as 23-24 balanced and would open 2 and rebid 2NT but North can't see 13 tricks.

I need a dealer for natural bidding.

With my strong club system regardless of dealer I find out about J at 5NT, but can't ask for J

Dealer ?

With N as dealer:

1N(12-14)-2
2-4(4, 5+, slam try)
4(kickback )-4(0/3)
4N (Q?)-5(yes +K)
5(rolling, partner will only pass with 0)-5
5N (still interested in grand, but no K/K)-6(confident about 6N, got K)
7N

With S as dealer:

1-1
2N (GF unbal)-3(semi forced, always bid this without massive distribution)
3(usually big 6-4, occasionally massive 5-4)-4
4(kickback)-5(2 without)
5(I have K/Q , bid 7 with the other)-5N (no, I have no black K, but still interested in grand)
6(K)-6
6(K not Q)-6(Q, K denied earlier, bid 7 with K)
7-7N (OK so you have K, AKxx, AKQxx, K, 4+2+5+2 = 13)

2-2* positive
2NT-5NT
7NT

I am probably biased by seeing the hands - in practice, either S or N would take a more conservative view and we would finish in 6.

The problem here seems to be locating North's jacks if South is in control, or the 5th diamond and good controls if North. QP methods probably manage this with ease, particularly those that also incorporate reverse relays, but it is more difficult for me.

1 = 15+ nat/bal or 18+ any
... - 2 = 4-5 spades, 2-3 hearts, bal, GF
2 = relay, usually 18+
... - 3 = 4234
3 = relay
... - 4 = extras, 4 controls
4 = relay
... - 5 = + controls, no control
5 = relay
... - 5 = no control
5NT = relay
... - 6 = 2 (or 3) of top 3 spades, 1 of top 3 clubs
7 (J not locaated)

I could also break relays after 3 and switch to key card asks in diamonds but finding those knaves is still going to be a problem. This might have been a good deal to include in our strong club bidding series.

My slam would be based on a "bean count " after a standard 2C opening :
2C - 2D! ( waiting, but positive )
2NT ( 22-24 ) - 3C ( regular Stayman )
3H - 3S
3NT - 6NT

Responder's 3S is showing 4 cards... since Opener could also have 4 cards and a slam might be a better place to play .

There may be a different way of handling this.... but you don't want to rebid 3NT ( which would also show 4 cards ) and have Opener pass .

Precision:
1 - 1NT
2 - 3
3 - 3NT
4 - 4
7

1 = 15+
1NT = 8-13 balanced
2 = natural
3 = support, 4 controls
3 = asks
3NT = third round control in
4 = asks
4 = doubleton heart

If I wanted to get more scientific, it could go

1 - 1NT
2 - 3
3 - 4
5 - 5NT
6 - 6
7

1 = 15+
1NT = 8-13 balanced
2 = natural
3 = support, 4 controls
3 = asks
4 = AK or AQ of
5 = asks
5NT = 3rd round control
6 = asks
6 = doubleton heart
7 = could be only 12 tricks in NT although it might be worth trying at matchpoints

on natural south's hand has to be evalued between 23 and 24 HCP, for me this matters as I have a range of 24+ that would prompt north directly into grand slam.

if evalued as 22-23 only I think north will end up in 6NT after finding there is no likely fit. So pretty much what helene said.

I agree with the second sentence, which is why my auction continues 5NT after 3. However, if 3 is natural for you, what is responder's forcing heart raise?

Easy playing a relay system and very difficult playing natural. I would get to 6 of course, but probably not 7.

I play a natural 5-card major system, but show number of controls after a 2-club opening, so:

2C - 2UT(4 controls, A=2, K=1)
3D - 4D
4UT (RKC 1430) - 5H
5UT (extras?)- 6SP
7UT

I think it is better here to show diamond support immediately after dealer's 3D, rather than to show the spade suit as a possible alternative trump suit, which might leave dealer with the problem of what to bid next.

4UT might seem unnecessary, since dealer already knows how many aces partner has, but I'm not sure how otherwise to ask for extras, and here 4UT followed by 5UT does the job. For me, 5UT direct after partner's 4D would ask parter to bid 6D/7D according to how many diamond top honours he holds.

After 5UT, I think it's best that partner now shows the spades, rather than bid 7D. Dealer then should have sufficient information to bid an inspired 7UT, or maybe I'm also influenced by seeing all the cards!.

How do you know the spade extras are QJ rather than just Q ? This is important as Kx-AQxx doesn't want to bid 7N, KJ-AQxx does, Kx-AQJx does.

Regarding my posts # 8 and # 10..... perhaps 3S should be an "either/or" ...
... that is, either 4 cards OR a cuebid for as trump.

-- If Opener does NOT have 4 cards , he then bids 3NT .

-- If Opener HAS 4 cards , he then bids an advance cue of 4C or 4D .

We tend to respond pretty light, particularly when we hold a major suit. Yes if partner has Qxxxx and out we might miss game, but somebody will probably bid spades to save us.

It's actually very rare these days to be passed out in 1 where you want to be in game, people should pass it out more but they don't.

We miss the Grand

2 - 2
2N - 3
3 - 3
3N - 6NT



2 = GF, waiting
2N = 22-24
3 = Puppet
3 = No 5Maj, but 1 or 2 4Maj
3 =
3N = No 4 card
6N = Let's try this


Yes...still playing Puppet over 2NT. Shoot me. ;)
