Wonder whether anyone can suggest a good auction for these hands after a 1♣ opening by South and a 1♠ overcall by West.

 

We produced the following

 

1♣ - (1♠) - X - (P)

1N - (P) - 2♠ - (P)

3♣ - (P) - 3♦ - (P)

3♥ - (P) - 4♥ - (P)

5♦ - All pass

 

No one was able to find the Diamond slam, though one pair did make it to Six Hearts doubled...

I wouldn't want to be in the diamond slam. The first objective seems to be to stay out of 3NT, and the second to get to hearts, assuming this is matchpoints. Perhaps:

1♣ (1♠) 2♥

2NT-3♦

3♥-3♠

4♦-5♦

 

Or after 3♠ opener might try 4♥, envisaging this type of layout.

I like your auction. Simple , natural and effective.

[Cyberyeti]

1♣-(1♠)-2♥

2N(12-14 bal not 3♥)-3♦

3♠(stop ?)-4♣ (can't be 544 or would have rebid 3♣, strong suggestion of 553 and good hand)

4♦-4♠(confirming 553)

4N(A/K♥)-5♣(A/K)

5N(A/K without Q♣)-6♦

 

we use notrumps to show the most expensive cue, with partner known to hold one of ♣AK, 6♣ instead of 5N would have shown AQ/KQ.

My analysis is somewhat faulty, though. 6♦ is pretty good - with hearts 4-2 it's almost cold, and even with a 1=5 break you have reasonable chances.

I saw someone once find the slam via an extraordinary sequence on a similar hand. IIRC the bidding went something like this:

[hv=d=s&v=0&b=11&a=1c1s2s(Michaels%20not%20denying%20club%20support)p2n(What%20is%20the%20minor%3F)p3dp4dp4s(Voidwood)p6d(My%20reply%20commits%20us%20to%20six)ppp]133|100[/hv]

I was going to post exactly this auction then decided to read the other posts. Obviously I like it :P

 

I don't see how N can bid the slam after S strongly implied some spade wastage, tho not a huge amount since he is clearly 2=3 reds on this auction (if one opens 1♣ with 3=2=4=4, I suppose it is barely possible he might hold that shape, but I don't have experience with that method).

[inquiry]

I don't like starting negative double with the north hand. So I fall into the 2♥ bidding group.

 

One might first, however, consider this auction...

 

Pass - (1♠) - 2♠

2NT - 3♦

4♦ - 4♠, 4♠ mild slam try,

6♦ - East is great for a slam try given a passed hand

 

But, ok, I admit I would open south 1♣ as well. After bidding 2♥, forcing, South does have a problematic rebid.

• 2♠ would probably show support, if not and it was waiting I would bid that, but for me it is "good support",
• 2NT would show a spade stopper,
• 3♣ a fifth club,
• 3♦ diamond values, but probably no longer a reverse, the question is would it promise a real suit, in which case it mis-identifies two cards in the hand (suggesting 45 in the minors, when really 34). So South has a real problem. (If 3♦ just shows concentration of values and inability to bid raise hearts or bid 2NT, then the auction is easy, but who plays that?)

Here is a reasonable auction with opponents passes not shown, with a curious Bluhmer cue-bid thrown in for good measure.

 

1♣ - (1♠) - 2♥

3♣ - 3♦ The 3♣ bid only misidentifies one card, Not a spade stopper, not heart support, a "fifth" club.

3♥ - 4♣

4♠! - 5NT

6♦ - pass

 

This auction, however if full of problems. The 3♦ bid is natural and forcing, the 3♥ is doubleton (most likely honor doubleton). The 4♣ is bidding out shape, and possibly finding correct strain of clubs. 4♠ has to be a Bluhmer cue-bid (Opener has denied spade stopper not once but twice), showing all his values outside of spades. 5NT is pick a slam, obviously implying good diamonds and only three card club support. But the problem is, opposite five clubs, North might just bid 6♣ which isn't a great spot instead of offering up a choice. If given a choice, South will suggest diamonds, obviously.

If I wasn't allowed to bid 2N, I would bid 3♥. The idea of rebidding Kxxx makes me ill.

I did not even check the result, neither i was talking about the outcome. I was mainly talking about the path you had chosen.

South's rebid after 2♥ is a normal problem of MSC from the BW.

Probably something like this:

[hv=d=s&v=0&b=11&a=1c1s2d(Switch%3A%205+H)p2h(To%20play%20opposite%20a%20weak%20hand)p3d(nat%2C%20forcing)p3sp4cp4dp5dppp]133|100[/hv]

 

North has to make a decision, but playing in a 5-2 fit with a void opposite a probably weak ♠ suit is asking for trouble, so 5♦ is safer imo.
