Any idea how to bid this one

[Lovera]

And about "cue bid before" if bidding goes (S-N) 1NT-2♣, 2♠ and because N is interested for an eventual controll in heart needs start to prepare cuebidding in diamond with 4♦ considering singleton as a king to know situation in heart having, in this case, 4♥(=controll). Subsequent 4NT(s) should not consider this one than answere is (one key remaining) 5♣(=1430)-5♦(=queen ?), 6♣-6♠.

Playing Weak NT (as the OP requested)

 

1♦ - 1♠

2♠ - 4♦...should get you there quite easily.

[Lovera]

After to have considered necessity of cuebidding, to extend this concept let us suppose this : in N spade and club are the same cards whilest heart and diamond are changed (7♥, 75♦) and in S spade and club are the same cards whilest heart and diamond are changed (8542♥, AQ♦). And now what happen and what can we do to solve situation ?

[Lovera]

The answer should be 3♥(=splinter )-4♦ because if not exactly so we are in trouble again. I find that to require two types of bidding (see also the precedent post) to integrate RKCB in this/these case(s) can be a point of aptention meaning : in what case or condition we can necessarly do so ?

If you can't open 1N or 1S on this hand, then 1C is much preferable to 1D. 40+ years ago Terence Reece wrote "don't bid bad suits on good hands". If partner can rely on you opening decent suits, (s)he is better placed to evaluate singletons opposite potentially wasted values.

Why open 1♠(?!) It's well known that with equal length in the black suits,clubs rank above spades for

bidding purposes. So 1[clubs is the correct choice...

. . . with equal length in the black suits...

 

Equal length? :blink:

I put the spoiler there because I feel the bidding is more geared to advanced than intermediate (or my idea of intermediate is insufficient)

 

 

 

NO OPP BIDDING

1n (15-17)

2h transfer

2s accept (close to super accept but just short)

3c game forcing natural 5+ but normally just looking for 3n and expressing concern about the red suits

3h down the road (when we convert to spades) this will show a cue bid in case partner is searching for slam. For now it shows heart stop(s) and worries about diamonds in case that excites partner. With the vast majority of hands with spade support we would just bid 3s but this hand is looking quite exceptional.

4d* splinter denies 6 spades (would have bid 4d over 2s) could be 5314 normally 5215 5305 5116 5206. 4h by opener would show 4 hearts and trying to sign off.

4n rkc for clubs. This is a superb time to take over since p will assume we have a club fit.

5s 2 w club Q

6s enough to bid small slam opposite a singleton responder should bid 7 with a void.

 

* it is a bad idea to splinter a singleton ace since p will downgrade the K or KQ when those cards are working well.

 

The above is planning realizing your hand can be quite useful opposite 55 in the blacks. You chose a line of bidding that not only gives your side a great chance at bidding slam but also keeps alive the club suit for rkc purposes if p is interested in slam and if we convert a contract to spades later responder will realize we have a good hand for spades and that 3h was a cue bid even though we were not strong enough to super accept.

Note that with the club and spade honors reversed it is far better to bid 3s over 3c to show the fit and rkc can be used to locate the spade Q.
