1. North, unless 4♠ was forcing. He might just bid keycard over 3♥, accepting that slam will be poor opposite Axxxx xx xxx xxx but otherwise good or excellent.

2. Assuming North's 3NT bid is systemic, South, for not making a slam-try.

3. Obviously North is blameless. Does South know that North is 2335? If so, he's worth 4♣ over 3NT.

[Codo]

1. North after south showed a gf with long spades

2. Did North show 27 HCPS? Then south. Did he show just 25? Still south. Can he have less? Never.

3. If you have no way to find out about the 5 card minor, you should not bid any slam.

[Fluffy]

1. I also think north is worth 4NT over 3♥, this will be very weird since 2NT is limited, but what other meaning might it have? If unsure of the meaning of 4NT I think he can jsut bid 3♠ and when partner bids 4 he will move.


2. I think the system is mostly at fault, also I think south might be worth something other than 2♥.


3. What Andy said, if north is known to be 2335 or maybe 2245/2236 south has a clear 4♣ bid.

[dake50]

1. North TIMID!
2. South TIMID! 7-suit
3. North TIMID! TIMID!

[Phil]

1. North. If 2♦ is GF, then 4♠ is just a weird call. I think I like 4♣.
2. QJTxxxx is not a bad hand.
3. South needs to make another move with 4♣. While its sort of a perfecto slam without wastage, South already knows there are no spade losers and that partner has 5 clubs.

After the 3D! check-back ( NMF for this version of Wolff ):
North only has denied 3 cards ♠ ( otherwise would rebid 3S )....
... and denied 4 cards ♥ ( otherwise would rebid 3H ) .
The 1C opening does not necessarily deny shorter ♦ for a 18,19 hcp hand.

So, Opener could easily be 2 3 4 4 .

hand one

Our 2n was underbid because of the singleton
K but now that we have found a large spade
fit the k is probably useless and irrelevant
but our hand has improved.

First p is virtually NEVER going slamming
missing the AK(Q) in ALL of the side suits.
Our hand is so good after p bids 3h the 5
level is almost certain to be safe unless
p manages to have xxxxx xx xxx xxx and I
mean ALL x's. Bridge is an exercise in
probability and opener should bid 4n over
3h not merely show a max because this hand
is a super max. When p shows 1 bid 6s and
expect it to be close to a lay down.

VERDICT blame N

HAND TWO

Responder is showing at least 6 spades and has denied
having as much as an A or K. Once again an exercise
in probability. The 5 level is a huge favorite to be
safe opposite any 6 spades so all we need to know is how
good are responders spades (both sides know QJTxxx is the
best the suit can be). After p bids 4h opener should bid
5s asking for good spades. Responder has no trouble
TRUSTING P and bidding 6s.

VERDICT blame N

HAND THREE

This one is a bit of a quandary since my understanding
of the wolff 3d is a checkback. The wolff systme I
learned a 3s bid (promising 5+ and slam interest) seems
like a better bid than 3d because it will allow opener
to better appreciate honors in your 5 card spade suit.

However we chose a nebulous 3d bid and learned little
from the exercise aside from the fact opener has at most
5 cards in the major suits (2s 3h but it could be less
ex hand 1 a stiff K in the majors). Are we now doomed
becasue our side has shown around 31-32 hcp and no
runnable long suit???

I think not-- the bidding makes it possible that opener
has a 5+ card club suit (if I had Kxxx AKJx in minors I
am opening 1c). If p has a 5 card club suit we might be
able to make a slam via ruffing spades and setting up
the 5th spade OR maybe even ruff a heart with our 3rd
club.

I would hazard a 4n quantitative bid and in this case
opener will gladly bid 5c and you can cue bid 5d they
bid 5h you bid 5s and they bid 6c. So for cowardice
above and beyond and possibly misusing wolff----

VERDICT blame S

[benlessard]

1-depend on what 4S meant, you are in GF, so 3S,4S VS anything else is a matter of agreements. If you often rebid 2nt with 4441 than you can play that 3S by opener is balanced and that 4m are splinters in that case 4S could be H splinters that is afraid to wrongside i guess.

South has some of the blame here, he would bid exactly the same way with Qxxxx,Qxx,xx,xxx. Its a bad case for fast arrival here, since 2NT--3H--3S--4S isnt slammish, when you have 6 spades and little else you should bid the same way (bidding 3H) planning to bid 4S (wrongsiding) or 4H (if you play retransfers) over 3nt. Therefore a direct 4H texas should show 6S and a working card and be slightly slammish. Hand like Kxxxxx,x,Qxxx,xx are frequently making slam.

2-South was asleep on this one

3- North has the most normal 3nt. Tough hand to bid. Note that we know north has 23 in the M so both 2335/2353 will give decent prospect for slams. However on a bad day hes going to have 2344 and a single H stopper AJx/KQx of H and 4Nt will fail.

So, Opener could easily be 2 3 4 4 .

So if Opener is 2 3 4 4 and South makes a try with 4C and you end up playing 4NT will that be a disaster?
The only agreement you need is priceless and simple: If you suggest a minor suit slam over 3NT the bidding can stop at 4NT.

Hand 1:

I'd actually open 1♦ with hand 1 devaluing the K♥ because I don't have a rebid I like after 2♣, we don't play the same responses to 2♣ btw.

Our auction would be 1♦-1♠-3N(4♠-4♦-(41) 19-22)-4♠-4N-5♦-5♥-6♠ and yes this is a routine response for us.

In your auction I agree with Gnasher, once partner shows a GF with 5+ spades, I'm not bidding anything non forcing.

Hand 2:

What did 3N show ? Without knowing this it's difficult to assign blame. The big hand needs QJxxxx/Q109xxx and out to make a slam decent. I think I'd bid 5♠ over 4♥ after which it's pretty clear to bid 6

Our auction would be 2♣-2♦-2♥(kokish style intending bidding this as a 28 count with these crisp honours)-3♠(failing to bid 2♠ shows 7+ spades or a 5+ 5+)-4N-5♣-5♦-6♠(if 5-5 would bid the second suit here)

Hand 3:

In your auction I suspect no blame. N has fairly tightly defined his hand, is maximum and been unable to show 5 clubs, S has a borderline move if he knows N has 5 clubs, and no move if he doesn't, same honours and 2344 is not good (but do you open 1♦?). Btw if my 2N opener showed 19, I would have done that, ours shows a good 19 as a minimum and I have no strong views about whether I'd open this hand 1♣ or 2N.

We'd bid 1♣-1♠-1N(15-bad 19)-2♣(asking)-3♣(17-19, 5♣ not denying 3♠)-3♠(5♠)-3N(2♠)-?

Now it's very close whether to pass or bid 4♣, if 4♣ is bid it's easy from there.

For those suggesting north should move on board two. How would South bid with 10xxxxx xx Jxx xx?

[ahydra]

1) both, possibly. I think North can do better than 4S, e.g. 4C (cue) or 4H (shortage) or whatever the system is. His hand is now worth more than 23HCPs. But on the other hand, South could try keycard over 4S now that North's taken care of his rubbish trump suit.

2) Definitely South. I assume N showed 25-27 balanced. As South I would have just blasted 6S.

3) This one is harder, particularly because I have no idea what Wolff is. If it's just asking for major support then I think the auction is fine. Perhaps South might push to a quantitative 4NT but this is imps, not matchpoints.

Like that, I'd play 5♠ and be unlucky not to make it.

[rduran1216]

ok, how about Jxxxx spades and dysentery outside.

I mean this kind of bidding is consistent with a 5332 0 count, which for the record is relatively likely given our hand.

That is a pass. Partner's 3N after the double negative may not be a strictly systemic & descriptive bid; partner may just decide that Ax Ax Axx AKQxxx is likely to be worth 9 tricks, but not worth exploring for an unlikely minor suit slam opposite a bust.
