Martian Standard:

1 - 2
2 - 2
3 - 3
4 - 4
4N - 7

1. 1 = Forcing and unbalanced
2. 2 = GF Relay
3. 2 through 4 patterns out declarer to be 5=3=5=0
4. 4N is 10-11 zzz points.

North can place South with the three Aces, and at least one of the red queens, so it rates to be stone cold if its the Q, or at worst a 50-50 shot to locate the Q.

Playing relays, there are two ways of getting there:


[Parity cue biding]

1 - 1N (5+; ask with 14+ HCPs)
2 - 2 (various, including s; relay)
2 - 2N (5+; relay)
3 - 4C (5=3=5=0; QP ask)
5 - 5 (10+ QPs, zooming into PCB: A, AQ of or nothing; relay)
5 - 7 (AQ of or nothing; must have A, AQ, AQ)

[RKC followed by specific card asks]

1 - 1N (5+; ask with 14+ HCPs)
2 - 2 (various, including s; relay)
2 - 2N (5+; relay)
3 - 4 (5=3=5=0; RKC )
4N - 6 (3 key cards; Q? -> lower bids would ask for other cards)
6 - 7 (Q, Q; what else)?

East passes as Dealer.

Whatever you open as South, West passes.

How do you get to 7?

D.


1 2NT1
42 43
4NT4 55
56 57
7

1. Jacoby
2. Void
3. Cue 1st or 2nd
4. RKCB (excluding the A given the void
5. 1 or 4
6. Asks Q
7. Q and K

All is well if Jacoby 2NT denies a shortage and therefore 4 promises a high card. If not you may need another try after 5.

Assuming that expert standard methods are being used, it is challenging but possible to reach 7S.

1S - 2N
3C - 3S
4C - 4D
4H - 5H
5N - 7S
Pass

Note that I am assuming that opener does not rebid 4D to show a 5-5. It is not that I do not like this approach, but rather that I believe that to make this bid both suits need to feature good quality suits. (The failure to bid 4C to show a void confirms I assumed the 5-5 jump bid approach.)

Thus 3C showed shortness, 3S showed no cue bid available and is waiting - one should not sign-off in 4S with such excellent trumps and welcome news about such useful shortness - and now opener's 4C confirms a club void. Now it is easy for responder to cue bid Kings having denied a red suit Ace with 3S. After responder's 5H bid, all that needs to be done is to check for trump suit quality with 5NT.


I like this sequence the most. Totally straightforward and logical. Once N denies Aces, he can start showing Kings. Simple.

Thanks.

D.

1--2NT Jacoby
5--5 Exclusion Keycard Blackwood (1430) --> 1 Key card
5--6 Spade queen? --> Yes and king of diamonds
6--7 Grand slam try: Do you have further values outside of clubs(e.g. king of hearts or a fifth trump etc.)? --> Yes, I do

Another ridiculous post by this author, partner held the same hand with the minors the other way round, the grand was almost no play (KJ doubleton onside required).

1-2N(good raise to 3 or better, 4+)
3(LSGT initially)-4
5-5
5-6
7

Not ideal, partner's spades might be worse than this but not by much in that he doesn't appear to have AK and 6 sounds more enthusiastic than other things he could have done.

**edit, actually it occurs to me that 3N showing 4333 and enough for game is a better bid than 4, now 5 is exclusion and the auction continues 5(1)-5N(Q?)-6(yes+K)-6(bid 7 with the K or Q)-7**

Another way we could have bid it:

1-2N
4(voidwood)-4(1/4)
4N(Q?)-5(yes +K)
5(I have one of K/Q bid 7 with the other)-7


1-2NT, 4(=Exclusion at fourth level)-4(=1/4 keys), 4(=?Q)-5(=Q plus K), 5(=?forQ/K)-5NT(=yes K)-7(Lovera)
