Answer: it doesn't. I end up in 4H, or possibly 5 or 6H depending on how lucky I'm feeling.

But lets assume I fudge a bit:

1C 1S
1NT 2D
2H 2S
2NT 3C
3D 3H
3S 4C
4D 4H
4S 4NT
6S

Explanation:

1C (strong) 1S (balanced, 3 suited or diamonds)
1NT (relay) 2D (4+ hearts balanced)
2H (relay) 2S (both majors)
2NT (relay) 3C (4423 shape)
3D (relay) 3H (4 slam points, where A = 3 K = 2 Q = 1. This would usually show 5 slam points but I'll happily admit it's a fudge)
3S (relay) 4C (1/2 top honours in spades, 0/3 in hearts)
4D (relay) 4H (0/3 in clubs)
4S (relay) 4NT (0/3 in diamonds)
6S (realising that you need to pitch a diamond loser on the hearts, and this doesn't help if hearts are trumps).

What would actually happen:

1C(strong) 1D (negative)
1H (Kokish) 1S (relay)
2H (min with 6 hearts) 4H (go away)

If it happens at all, it's going to go -
1C*-1D*-
1H-2H-
2S-3S-
4NT**-5C-
5D-5S-
6S...
*strong club and negative response
**keycard for Spades, the only way i think i would get there without a double agreement 6 keys sequence or learning a relay system. 1H thru 3S all natural.
Unlikely perhaps, but ya never know.
I'd rather have a bottle in front of me than a frontal lobotomy - but it might improve my bridge.

Because the non-natural system section, you allow me for:

Pass - 1
1 - 1NT
2 - 2
2 - 3
3- 3NT
4 - 4NT
6 - pass

Pass= 13+ any shape
1= 0-5p. (no Ace OR King+any Queen) OR 6-11 part balanced
1= relay (no 4333/4432 13-22p.) no 13-15p.: 5+c m+4cM, or only
1NT= 6-9p. 4333/4432 or 5m332 (no 2/3 toph.)
2= positive relay
2= 6-7p., or 8 bad points. no Ace + any King
2= relay
3= 4/4 Majors, 2/3 or 3/2 in the minors
3 - Control asking Bid ( order) **
3NT= King or Ace
4= SLam Asking Bid, = trump *
4NT= Queen, no Queen in doubleton

*After 3NT I can ask with 4 for exact distribution or through 4 End Signal play a game or ask for further Control cq. do a Slam asking bid.
4 = normally: further control? but because of control Ace no further control can be there, thus a SLam Asking Bid and =trump. Resulting that 4 = SLam asking Bid for.

1 Ace of 5 () already mentioned, thus without Q RR passes the 4 bid.
====

Suppose West has Ace and East has K ,
I will have a problem because if no Q I have to play -if decided to investigate furtheron- on the 5-level.
No system is perfect <_<

-----
** note: no control is impossible because 3 Queens will be downgraded to a 0-5 pointrange
=====
Finally, because starting with a Pass=13+ is easier than starting with a fert.
If East has to open, the bidding will be symmetrical with the same information.

For your info:
1 - 1
2 - 2
2 - 2
3 - etc.

1= 0-7 (if 7 then no Ace+ any King)
1= 13+ (no 13-22 4333/4432 etc.)
2= 6-7 bal. 4333/4432 or M or any 7222 with specification (if 4p.=Ace if 5p.=K+anyQ)
2 = positive relay
2= any 4333/4432
2= relay
3= again the 4/4 Majors and 2/3 or 3/2 in the minors
freedom to use any bidding system
is vital to the development of bidding theory

There seems to be two options, the cautious 3 "weak raise" forgetting about 's and the over-optomistic 1 (kaplain inversion) before trying to settle into some number of s. After the 3 bid, are lost but if responder sniffs at first, the bidding might be.

1 - 1
2 - 2
3 - 4
4NT - 5
5 - 6
Pass

where,
1S = 0 to 4 's
2D = four card S supprt
2S = signoff attempt
3D = forcing, game try, short clubs for sure
4S = I have enough to accept game try after i tried to signoff at two, no wasted C
4NT = RKCB for spades
5C = 1 or 4 keycards
5D = spade queen ask
6S = spade queen, no side king

With my f2f partner:
1 - 1 (15+ any ; 0-5SlamPoints any distribution)
1 - 2 (relay ; 3-5SlamPoints & balanced)
2 - 2 (relay ; 4-5)
2NT - 3 (relay ; 4-4-)
3 - 3NT (relay ; 4SlamPoints)
4 - 4 (relay ; 0 tophonours )
4 - 4NT (relay ; 1/2 tophonours and 0 tophonours )
5 - 5 (relay ; 0 tophonours )
6

Opener knows about AQxx-xxxx-xx-xxx, the known hand will play, but it's laydown anyway...

Ah, this hand makes a good (fictional) story.

At most tables the bidding went 1:2,4. North has Qxx so this makes exactly.

One unfortunate pair got to 6 on these cards. West decided his hand was only worth a game try of 2 over 2, and East (who had been reading too much about how 4-4 fits can be better than 5-4) decided to raise naturally to 3. This got West really excited, and he bid 4NT (RKCB for spades) and followed up with 6 on finding partner with the AQ. Down two.

Actually playing WJ2005 (approx.) one of my partners playing with his junior partner (sorry, no more junior here <_< ) bid simply:

1* - 1
2** - 2***
2 - 4
4NT - 5
5 - 6
Pass

* Polish
** Odwrotka
*** 4-card and minimum

What's this system you are using Ben? Doesn't look like inquiry2over1. Using KI with 4-card support is AWFUL!

The only reasonable start in your system seems 1H-2H, and it might go:

1H-2H
2S-4S
4NT-5C
5D-5NT
6S-all pass.

Seems like you can't stay out of 6S if opener tries with 2S.
Please note: I am interested in boring, bog standard, 2/1.

Playing fairly standard methods, as I do with Elianna, the auction will start:

1-2...

Now opener has some decisions to make. Honestly I wouldn't fault a direct jump to 4 on the west hand, in which case slam will be missed. However, it's certainly possible to imagine a spade fit playing better than hearts (2 only promised three-card support after all):

2 (natural game try+) - 3 (choice of games)
4NT (1430 rkc ) - 5 (one)
5 (Q ask?) - 6 (queen but no side king)

Playing Sam Ieong and my current relay methods:

1 (strong) - 1 (5+ hcp, 2-6 321 points, balanced or 4+)
1 (relay, either GF, or a 5+ major) - 2 (balanced 5-8 hcp hand)
2 (relay, GF) - 2NT (some 4432 with doubleton )
3 (relay) - 3 (4-4-2-3)
4 (sets ) - 4 (basically forced)
4NT (1430 rkc) - 5 (one)
5 (Q?) - 5 (Q no K)
6

Playing Josh Sher and my current methods:

1 (strong) - 1 (less than GF)
2 (both majors) - 2 (which is longer?)
2 (longer hearts) - 3 (prefer the 4-4 fit, gamegoing...)
4NT (rkc) - 5 (one keycard)
5 (Q?) - 6 (yes)

I am very skeptical that non relayers would find 6S here. I sure wouldn't.

Weiss clb:

1c=1d
1h=3h
3s=4s
5c=5d
6h=p

1c=strong
1d=0-2 controls (AK)
1h=~17-20, 4+h, may have longer minor
3h=invite in strong club context, 4Hearts
3s=asking
4s=AQ on this auction
6H=end, no use looking for Grand

common problem is to find a 4-4 fit after finding a 6-4 fit :lol:.

The problem with this auction would be partner not realizing that 3H bid will often not have more than 6 hcp so what are they going to do with club and d loser so best to just bid 4h. The key would be to have a good understanding of how limited 3h is and after partner shows up with 6 hcp that wll be limit in 5H and sign off, too hard to find 6spades I think.

To those who start 1H-2H-2S-3S-4N...why is 4N keycard for spades? Would you ever bid 2S with less than 4 spades (3613 slam try)? How would you then make hearts your agreed suit again?

not even the non relayers (happy with Ace + Q ?), in the relayers camp it's a mess too.

I have posted some months ago a remark that bidding such hands, specially in relay systems , needs - although with the actual hand it should fit wonderfull for your system and you reach the 100% contract - a fair approach.
I mean: what if the honours are placed differently in the framework of the sequence sofar and the received information.

mr1303: (although under admitted fudging circumstances)
4 level = auto 5-level with Queen too.
4 relay and f.e. 4NT= + thus Q, KorQ , K or Q

----
Free:
if Q?
OR
after the 4 relay: 5=K orQ and K orQ and thus Q

------

Inquiry:
question: Ace will that be welcome if you know partner is short in ?

------

I may suppose the starting point is a safe contract, best defence/lead

Best regards,
Marcel

P.S.
For the sake of good order:
the result of my given bidding sequence does not matter me, it's the principle that counts for me.

i'm with justin on the several auctions i saw that bid rkc... why was it for spades, aren't hearts set? anyway, my weiss bidding is slightly different from mike's, which means his is probably right

1c : 1d
1h : 2h
2s : 3s (A,Q)
4d : 4h
5c : 5d
5h

responder has xx(x) in diamonds and clubs, making it even less likely we have a spade fit.. i don't see any way to get to spades, even if i judged the west hand to be less than a 1c opening (i wouldn't) and opened it 1s

Hello Jlall

I play two way game tries. 1H-2H-2S* asks partner to bid 2NT unless he has soft values concentrated in clubs or diamonds, when he bids 2S-3m. I can evaluate better what his soft values might be worth.

1H-2H-2S*-2NT*-3H* is a long suit game try in Spades(you skipped over both minors after showing a 'long suit' game try.

With 6331 pattern you make a direct short suit game try 1H-2H-3m and 1H-2H-2NT* is the substitute bid with short spades.

Unless you have some special agreement, after finding a 4-4 spade fit, many people play that 4NT is RKC for spades.

If you hold 3=6=3=1 and you play two way game tries. Spades are never considered as a possible trump suit. 1H-2H-3C* direct bid show a short suit game try. Whether partner bid 3H or 4H or 3NT*(serious or non serious) or some bid, 4NT is RKC for hearts. You never found a 4-4 spade fit because it did not exist with your 3631 example.

Regards,
Robert
