Pretty hard to avoid slam. ask for feature find K♣.
Needs one of two red suit hooks I think. Even without Q♦ have a shot.
On non-heart lead makes with no hooks.

What is the meaning of 2nt and how to reply as opener

Many who play "feature relay" show a side A or K at the 3 level if the hand is not minimum, and a shortage at the 4 level. 3 of the major is for minimal hands.

This relay is used for hands who want to investigate game or slam ig opener has a good (and fitting) hand.

Othe relays exist too. And even "feature relay" can have different follow-ups too. Mr Ace will probably explain better than I do

[pescetom]

We play 4C as Kickback RKCB over any weak 2 opening, which takes a lot of guesswork out of slam bidding in a situation like this.

South ascertains at a safe level that opener has the Ace of trumps plus the K of clubs and can now place the best contract.

We Play Ogust. 3H shows. 9/10 HCP.and aa weak 6card suit.( Well,we knew the suit was weak already) So he can have 4HCP in Spade AND 5/6 outside.I am sure any 5HCP will be enough for 6NT.
2S—2NT
3H**6NT

6N by S makes regardless of hooks (You table Q♦ and whether it wins or loses you have 6+1+3+2)

6♠(N) is better than 1 of 2 in that you can try to ruff down the other heart honour before taking the diamond finesse or playing a squeeze on a heart lead unless it's single, but you want to be in 6N.

If you play feature, then Timo's auction is easy-peasy.

If you play some form of Ogust, it probably goes something like this:

2S 2NT(1)
3H(2) 4NT(3)
5D(4) 5NT(5)
6C(6) 6NT(7)

(1) Ogust - asking about opener's hand
(2) Good hand (for a weak 2); bad suit
(3) Key card
(4) One (or 5C if you play 1430)
(5) Have any Kings?
(6) Yes, Kc
(7) well, with the Kc, better to have the lead come up to the red suit tenaces.

Cheers,

When p opens 2s a critical look at your hand will make you realize that 10 tricks should be at worst on a finesse (50%) or a double finesse (75%) and that is when p opens a sub minimal Axxxxx and out. Once you picture the reasonably easy 10 tricks the next step is to investigate slam. I freely admit to being a feature fan and the 2n bid asks opener for a feature (A OR K) if they are near the top of their range (8-10). If opener shows a feature other than clubs we can toss 6n out the window as too dangerous but here we have a pleasant surprise and a 3c bid comes our way. We can now count 6s 1h 1d 2c and that is only if p has the spade A and the club K (and they should have more for their 3c bid). Ten top tricks some other honor in openers hand
and suddenly counting to 12 tricks should be no worse than the odds of making game opposite a dead minimum. We can safely choose 6n because of our double club stop and this can be beneficial to play of the hand because we might be able to delay tackling the spades (and the extra entry to the N hand) in nt.

There are 2 basic ways 2 NT is used by a partnership over a weak 2 bid. In both cases, 2 NT is forcing for 1 round. One asks for a "feature" which is normally a side A or K. The other is the Ogust convention which asks the weak 2 bidder to describe his weak 2 bid by some artificial rebids. The rebids to Ogust are:

3 ♣ - bad hand, bad suit
3 ♦ - bad hand, good suit
3 ♥ - good hand, bad suit
3 ♠ - good hand, good suit

Which method that any partnership uses is by prior partnership agreement. Both methods are widely used among good players, so it's difficult to say that either should be preferred.

If you are playing "feature", as many have indicated, your proper response should be 3 ♣ showing the ♣ K. The actual hand looks like a fairly normal weak 2 bid -- 1 1/2 QTs, 9 HCP and decent suit, so you should show the feature. The only time you shouldn't show a feature is when you've opened a subnormal weak 2 bid, then you simply rebid your weak 2 bid suit. So if "the devil made you do it" and you bid 2 ♠ on something ♠ 1098xxx ♥ xx ♦ Qx ♣ K10x, then the proper rebid over the feature request would be 3 ♠. Obviously, if you don't have any feature, you also just rebid the weak 2 suit. That alerts partner that either have no outside feature or have a bad hand. In most cases that will help partner/responder decide what to do next.

If you are playing "Ogust", with a fairly normal weak 2 bid, you'd choose to rebid either 3 ♥ or 3 ♠ showing a "good" hand. Most normal weak 2 bid agreements are for a couple top honors in the weak 2 suit, so I'd probably opt for a 3 ♥ with actual hand you asked about. Maybe some dedicated Ogust users could provide some better insight into the proper response. As for the subnormal example I provided, that bid would be an easy 3 ♣ rebid -- bad hand, bad suit.

Responder has a huge hand opposite the initial weak 2 bid of 2 ♠. It's more than enough to ensure game in ♠, so responder should seek to find out about the 2 ♠ opener's hand with a forcing 2 NT response.

Why is the hand so good? ♠ KQJ are sure to solidify 2 ♠ opener's suit. Even if opener's suit were ♠ 765432, there'd be a 68% chance of only 1 loser in ♠. Anytime opener holds the ♠ A there should be no losers. In addition, the hand has the 3 outside As including ♥ AQ (1 1/2 QTs), that amounts to a total of at least 6 1/2 tricks to cover potential losers in the 2 ♠ bidder's hand. If the weak 2 bid is made on as little as ♠ A and something additional, there's a great possibility that 11-12 tricks will be available.

After a 3 ♣ response to "feature" or a 3 ♥ response (good hand/bad suit) to "Ogust", chances of slam got even better and responder can continue with the agreed A asking bids. Note that responder can see there are not 2 quick losers in any suit and two As are not missing so A asking is OK.

Your maths is up the spout, 68% chance of a 3-2 break is correct, but not with only 4 missing, you will have a 6-3 fit.

Yep, thanks! Getting old, it's really a 90% chance of no more than 1 loser.

This hand can be interesting in the case that for "feature" is allowed also the Q. Lacking K in partner club suit it makes arising an ambigueous situation that can require, at safe level,an ultherior bidding to clear if there is the King or Queen (other almost a Q aside).(Lovera)

This one can be interesting to read (and to have as guidelines) about "the weak two" bids: http://bakerbridge.c...2/deal00.html#1
