Here's a better hand where slam has no play:

KQxxxx
AQx

KQ

He would need a hand about this good to bid 5H with xx diamonds. The odds of the opps bidding this much when we have all the other points and they have 9 diamonds seems extremely low. So this whole parlay seems near-ridiculous to me.

Ok i concede a singleton or void diamond with partner is more likely.

We encouraged partner to raise hearts when we bid 3.  I would expect partner to bid 5 more often than not with a heart fit.

Well, partner is very unlikely to be bidding 5 over 5 with 3 card support in a balanced hand. Why volunteer to play in an 8 card fit at the 5 level when you could be defending 5X? And if these hands are ruled out, slam is suddenly looking much better.

Just because you have three card support doesn't mean that you have an eight-card fit. Sure partner's 3 only promised five hearts but he will have six or seven hearts fairly often.

You can't have it both ways and assume that they have a ten-card fit and we have only an eight-card fit.

When we have not yet shown a fit there is a bigger pressure on us supporting at the five-level than for bidding on after we have already established a fit at a lower level. If we do not show support with three-card support then partner with six or even seven bad hearts won't necessarily be able to rebid them.

6H. While may not make, if I bid 5H, I'd want partner to raise on a hand like this.

Hi,

I would pass.

Going plus is more important than reaching
a slam, which may or may not be just a little
bit abvove 50% or 60%.

Let me give partner's hand just because. He had KQJ10xx Q10x Q QJx, some would say this is not a 5H bid. In fact, you might go down even in 5H!

I did bid 6H, thanks for the responses.

And I thought that I was one of the most pessimistic bridge players of all time!!

We are looking at the A spades, the A clubs.... and the heart K and partner is bidding 5. While the opps are already at 5, and we are playing partner for 2 diamond losers???? It may happen, but it's about as likely as getting hit by a truck the next time you cross the road.

Slam bidding is about controls and tricks. We have the controls, and a wonderful holding in partner's major. Slam comes with no guarantee, but it is the height (depth?) of pessimism not to bid it.

Yes this is a bad hand.

But it illustrates the pressure partner is under to bid 5.

If you would pass with that add the K and slam is still hopeless.

I did later concede that two diamonds was relatively unlikely.

Having all te aces, and the ace in partner's long suit I think we are favurite to run 12 tricks, havinf pened a 5 card suit really helps n this auction, 6 for me.

Oh yes, nobody argues that slam is a lock. But most seem to think that it is likely enough to bid on.

I understand.

I am trying to think how best to do a simulation here.

It depends on how often partner will push to the five-level with rubbish.

I will look at it some more later.

If partner is bidding 5 on hands like the actual one, which is beyond sick, then I'm sure pass will be the winner.

Yes, it seems that you need to do 2 simulations.

First, a simulation to convince yourself that routinely bidding 5/5 is a big loser.
Second, use the results in your second simulation, such that partner's 5/5 is for real.
That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

We are on a guess. If we're playing that pass and pull shows slam interest, then I pass--partner may be stretching for his 5 over 5. 6 isn't grossly wrong--I just think pass is going with the odds.

I am happy to learn:

You open 1 Spade with
KQJ10xx Q10x Q QJx,

when you have to bid again, your rho just did bid 5 Diamond over pds 3 Heart.

Your choice?

1. pass, we may even go down in 5 of major?
2. Pass and pull pds double to show a good hand for slam?
3. Pass and pull, this shows that my hand is not suitable for a slam?
4. X this is optional, I do not need to show my solid spades or my heart fit. I have no trump tricks, but well double is at least successful in the post mortem?
5. 5 Heart shows support, no, this is sick, no even beyond sick
6. 5 Spade. This will slow down partner because I hide my support and we may play at the 5. level?

I mean, after this start of the bidding, you do feel a little pressure don´t you?
I totally agree that 5 Heart was no kind of a beauty, but if this is sick, what is healthy?
Kind Regards

Roland

I don't understand why everyone's talking about hands where partner has only three hearts. Surely a greater risk is that he has a moderate hand with four or five hearts? It would be hard not to bid 5H with KQJxx Q10xxx x Kx or Q10xxxx AQxx x Kx.

I'm not arguing against bidding 6H, particularly, but just trying to provide more realistic examples of the downside.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

Instead of 5H, partner must double when seeing 2xD losers. So 0-1xD-loser and 6H stands out.
