How do you bid? As usual, the system no-frills 2/1. 3C by opener shows extras.

3NT looks good with a NT slam a possibility opposite a North with more than his shown extras. 4NT could start this enquiry.
However, 3♥ to show an initial preference for ♥ (either 3 small or with honour(s)) as here may be preferable looking to play a slam in the Moysian fit or convert to NT later.

Subsequent bids are then
3♠ - denies a ♠ stopper with a weakish ♥ suit
3NT - weakish ♥ suit ♠ stopper choice of games.
4♦ - 3+♦ GF given the extras
4♣ - 5+♣ with a singleton
4♥ -I have 2./3 top honours.

To me (as a non 2/1 player) 3N would show a minimum 2/1, so I bid 4N (4♦/♠) would be the ace asks, I'm just showing a 3N bid with extras), now partner just bids 6♣ and I can choose to pass or bid 6♥.

Do you continue?

What if your partner shows up with: KQ, AJ98x, xx, KQJ10?

That's about a king worse than the original hand in terms of trick taking potential (the 5th club is a pretty much certain extra trick), I'd pass 4N with that assuming when I showed "extras" with 3♣ 15 was about minimum.

K&R gives 18/16.8 so closer than I assess it, but I think enough difference.

Maybe I'm just old fashioned (maybe ) but I have an adverse reaction to using Keycard with an uncontrolled suit. Maybe that's a leftover from years of simple Blackwood.

NOT keycard, 4N is quantitative, I said 4♦/♠ would be KC in the suit below

+++++++++++++++++++++++++++
I rank
1. 3♠ = 4SFG. When partner bypasses 3N, your hand improves.
2. 4N = INV.

I wondered about that, but how are you planning to continue if partner has nothing more to show and rebids a default 4♥?

Count me for a natural 4N. Even if you don't play some form of kickback, you have 4♣ to agree clubs first so it doesn't make much sense to play 4NT as keycard.

Interesting, but I don't see what it has to do with 2/1, however you define no-frills.
3♠ no longer needs to force to game (2♦ did that) and is basically a stopper ask here IMO.

I would raise hearts inviting a control-bid, although I recognise that is not mainstream and mikeh will say I am masterminding again.

Frankly, I am surprised anyone is thinking about a NT contract with partner describing a 2 suited hand and my holdings in his presumed weak suits are only Axxx, and Qxxxx. Sure, not both suits are open but one may be and if so the clubs don't have to be running. In other words, it looks like a suit contract is better - at least to me.

I don't think it masterminding at all. There is no reason to believe that a NT contract is better and partner could still hold a 64 hand while a 5-2 may play just as well if not better than NT. Another reason I like 3H is that it gives partner a chance to continue to tell us how much he likes his hand, and personally I don't think responder has enough to unilaterally commit this hand to any slam.

[DavidKok]

I don't think bidding 3♣ with a 6=4 is normal, taking up a level of bidding space to show clubs instead of the extra heart.
At any rate I'd bid 3♠, fourth suit. 3♥ would show 3 of them, and I don't have any other bid. I'm not exactly eager to play 6NT, even if partner has extras, so 4NT is a distant second.

If partner is lacking a spade stopper they might have a problem - say 2=5=2=4 or even 3=5=1=4 with weak spades. Especially if partner has extras that might be awkward to bid. But my alternatives are hardly better. And with, say, 5=5 (hearts-clubs) or 1=5=3=4, partner can explain precisely what they're holding. Now that I think about it, partner might even try 4♦ on the '2=5=2=4, weak spades, extras'-hand, because those extras have to lie in diamonds.

This auction is an example of really needing good partnership understanding. Does 3♣ show extra values - or perhaps a minimum with a fifth club? If partner bids 3NT over 3♠, does that show an OK 14 points, or is a reasonable 17 still in the picture? And even on the shown bidding problem: does 3♥ promise 3-card support?

Over 3♠, I intend to pass 3NT, correct 4♣ to 4♥ (this shows a not-necessarily-strong 5=5 for me), pass 4♥, and get very excited if partner bids anything else. On a bad day 3NT is cold and 4♥ a disaster.

I suspect you might have missed the part of the first post where 3♣ promised extras.

[HardVector]

You need more information. That's why you should bid 3s, partner's response will give you that info. I'd be voting for anything but 3n, that would give partner a good hand with nothing wasted in spades. I'd be perfectly happy to lay down the KQ♥ as dummy verses xxx when I go for a heart slam. Partner may bid 4♦, however. That opens up 7♦.

3C shows extras. A 2H rebid does not promise 6. Opener can be 54,55,64,65, or even 66.

2♥ doesn't *promise* 6, but you'd still bid it with virtually all 6-4 hands, wouldn't you? If partner continues with 2♠ or 2N, your next 3♣ bid now shows the 6-4; if partner bids 3♣ you're also happy, while if you hear a 3♦ rebid you probably don't want to show 4 clubs anyway.

If partner is 2524/3514 I may well want to play 4N/6N, partner will show extra shape here if he has it, so we're likely to play in a suit opposite 6♥ or 5♣ or 3♦.
