I'm afraid I might get into trouble with my favorite gadget.
With suit agreement, I'm tempted to launch into RKC ( by South ), and I'm only saved from destruction if North doesn't give a "void reply" :

1D - 1H
2S! - 2NT! ( artificial GF -- asks )
3D! - 4D ( long ♦, no 4s, no 3h -- agree ♦ )
4H! - 4NT! ( kickback RKC -- 2nd step = 1 key )
5D

But if Opener had the ♥A instead of the of the ♠A, slam is practically a laydown.
Tough problem.

"Opponents silent" appears to be unlikely, but I guess it is possible.

1♦ -1 ♥ (Natural)
2♣ - 2 ♥ (Rebid in diamonds, unlimited - 9-11, 6 hearts)
2♠ - 3 ♦ (Values in spades, forcing 1 round - Natural)
4♣ - 4♦ (Slammy with diamonds - Better than 5♦, not 3 aces)
4♠ - 5♦ (Excatcly 2 aces, cuebid in spades - At most one ace.)

1♦:1♥
3♦:5♦

[mtvesuvius]

1♣ - 1NT [15+ Any; Semipositive with 5+♥]
2♣ - 2♦ [GF Relay; 4+♣]
2♥ - 2♠ [Relay; 5-5+]
2N - 3♣ [Relay; Spade Shortness]
3♦ - 4♦ [Relay; 0625 with 4 AKQ points]

After this start, we'd be in 6♦ probably... By breaking the relay after 2♦, perhaps we could survive:

1♣ - 1NT
2♣ - 2♦
3♦ - 3♥ [Natural Relay Break; Natural]
4♦ - 4♠ [Setting Trump & Demanding Cuebids; 1st(2nd) Round Control (4♥ is RKC)]
4N - 5♦ [RKC for Diamonds; 1/4]
All Pass

[whereagles]

I would reach 5♦ nearly all the time, with a slam-try in between.

[tolvyrj]

1♦- 11- 16 2+♦- 1♥ 7+ hcp.4+♥-
2♣art. forcing for round- 2♥ waiting probaply 5+♥-
2♠ strentgh in spades- 3♣art. asking stopper
4♦long suit, no ♥,no ♣stopper- 5♦with agony but KJ in ♦must be useful
2♠r not a suit cause it would have been bid instead 2♣, KJ in♦with void in ♠covers only 2 losers and prd has them at least 4 cause opening was not 1♣ artifical and strong, otherwise opener has shown as strong as possible.
Not very convincing i know, but thats our system

Hi,

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

(1) 5 card major system, weak NT
(2) forcing, 6+ diamonds, at least inv. strength
(3) relais, accepting the game invite, asking for
further clarifiction
(4) denies 3hearts
(5) slam interest
(6) Cue, showes Ace or king in spades, denies the
Ace of hearts, the alternative is 4NT
(7) nothing left to say, showes 1KC, with 2KC, 4NT

With kind regards
Marlowe

South opens 2♦ = multi, either weak two in a major, a really big balanced hand (22-25) or 9 1/2 trick minor one suiter. We may be stretching for the 1/2 a trick here
North will rebid 2♠ out of fear opener had a weak two in spades.
South will rebid 3♦ to show the minor one suiter. Now game is a foof, and slam is possible.
North might try a splinter in spades, since he has more than adequate diamond support
South will not be happy with the spade splinter and will signoff in 5♦
North will look at his spade void and undisclosed heart king and wish he could do more. He can't.

2D - 2S
3D - 4S
5D - pass

I don't mind the 1/2 trick but where is the 9th trick vs a void or stiff ? 4 loser doesnt mean 9 tricks hand.

[Siegmund]

No laughing, now:

2C (~21+ or 9+ tricks) - 2D (waiting, better than a bust)
4D (9 tricks in diamonds, less than normal 2C high-card strength) - 5D (OK, I may have two tricks for you, but I can't see 3. If you wanted me to cuebid side kings you could have chosen a different bid; 4D said "count your aces and trump winners, and raise accordingly.")

And yes I think 9 tricks is a fair estimate, MrAce. Opposite a void you need an honor to drop (youll have to guess whether to lead low to crash a doubleton king or high to smother a doubleton jack, if nothing falls under the ace), opposite a singleton all you need is an even break OR a lucky drop.

[Cascade]

5♦ All Pass

[akhare]

Are we red? If so, seems like an easy enough 5♦ opening.

Opposite a singleton small, you still have 65% chance of losing only one diamond (stiff king, stiff jack in either opponent hand, or 2/2). Opposite stiff K or J, obviously chances for two diamond losers decreases remarkably. Opposite a void, you need to catch Jx or stiff king, something like that, decreasing the odds considerably. Opposite a small doubleton, you are up to 89% chance of losing only one (at most) diamond (assuming you can get to dummy if need be). However, not need to be so pesstimistic.

So what are the odds of partner having a diamond void? Well, there are 5 diamonds out, he has a 1/3 chance of having each of the five, so for him to have none would be unexpected. But against the majority (well more than 50%) of possible hands, it will take 7 diamonds (or more) and two spades. It is hard to imagine the 1/2 trick, but the solidity of the diamond suit (T987) means you can benifit if you catch a singleton honor in their hands. I stand by my original assessment, this is only an overbid by the 1/2 of a trick, and with this hand, I would open it this way all the time -- because I am not likely to stop short of 5♦ anyway, might as well try for slam on the way with 2♦ than just opening 5♦ or risking partner passing 3♦ rebid with, say, a doubleton spade and the stiff diamond king and pretty much out.
