we don't have the Q, I'd have bid 6♥ last round.

I counted my cards again, now I have 12.

well i counted the cards and they look like 3613=13. My problem is I counted the tricks and came up with 6♥2♣2♦2♠=12 so not sure why I am so hot to trot and bid a grand

[Codo]

I have twelve tricks if I do not lose a trump. Why shall I look for 13?

[zasanya]

The hand has only 12 cards.I am assuming 6 card ♥ and a 6-3-2-2 or 6-3-3-1 shape.
Let us calculate acceptable odds for bidding vulnerable grand slamIf you bid grand make you score 2210 .If opponents bid only a little slam they get 1460.So your gain is 750 points which means you gain 13 imps.If you bid grand and go down 1 and they bid a little slam and make your loss is 1430 which means a loss of 17 imps .This means mathematically you will break even in the long run if you bid (17X100)/(17+13) =56.66% (say 57 %) slam.
If we assune P has 3 card ♥ then chances of catching Q are 40+12.5+5=57.5
Just about break even.If P has 2 cards in ♥ then chancs are of catching Q are a trifle less than 50 % .Not worth it.On the other hand if P has 4 card very high % of catching Q.about 88%.
I wont bid the grand but I am a pessimist
If Heart suit is 7 bagger then I will as if P has 3 cards chances of catching Q are very high and reasonable even if P comes up with 2 cards.
At mps it depends upon the field .I will not bid grand in an unknown field as most people dont bid grand unless they are very sure.

Why are we so sure that the other black suit loser is covered?

Combine this with with the fact that we're missing the trump Q, and I'm comfortable with passing.

[gwnn]

with 3613 it's a 6♥ bid last time, wtp?

[dcohio]

I didn't have the hand record when posting this, but I found it now,

Change the spade suit to: KQx and now do you bid grand?

I definitely counted 13 winners IF the heart Q could be picked up...

[gwnn]

with 7 hearts it would be a 7♥ wtp hand. with 6 hearts it's 6♥ wtp. bridge is simple.

I thought texas transfers are for hands not interested in slam.

[gwnn]

it's like this:

transfer then 4N=quant
texas then 4N=rkc (you don't care about anything else)

transfer then 5m=void and slam try (i think)
texas then 5m=exclusion

[aguahombre]

Yeh, Gwnn....unless you are using the Meckwell toy. They apparently use 2-level xfer, then 5m as an answer to an invisible RKC which didn't occur. So the bid shows a long major and the number of Keys to partner all at the same time.

[mikeh]

Partner has shown 14 hcp, so he certainly doesn't need to hold a side Queen that would take care of our side loser in the blacks...we get one pitch on the diamond K, but then have another black x with which to deal.

To me, at mps, 6N seems clear, while at imps, I'd bid 6♥.

6N may be cold even with a heart loser, and will not usually play worse than the suit. But since there is no imp gain for 6N compared to 6H, and 6H will play better on some layouts...we will usually have more squeeze potential in a suit contract and partner may have a 5 card suit that can be established by ruffing...I'd always bid hearts at imps.

BTW, partner should be denying xxxx in hearts....opposite a known 6+ suit, he should show the heart Queen if he has 4 (or more) hearts.

One should generally avoid slams that are not substantially better than 50%, unless needing a big swing. This is especially so when there is some chance that even small may be missed: imagine partner holding 14....and opening 1D and rebidding 1N over 1♥. I would expect, in most mp fields, that there will be a significant number of game bidders. Even if I held KQx in spades, where I would expect virtually the entire field to be in slam, this is not a hand to venture grand on....if it makes, you turn average plus (your expectation in 6N) to a top, while if it loses, you turn average plus into a zero. And it is worse at imps.

[jdonn]

We have like 11.5 tricks and partner has 1 to 3 more points, right? Just making sure I wasn't reading incorrectly...

[aguahombre]

So a total of 12.5 to 14.5 (do I need an emoticon?) tricks available makes good odds if we weren't missing a big card, which we are since partner cannot have four small hearts.

It turns out that you were reading incorrectly

The OP stipulated 1N was 14-16, and he has shown 2 Aces and 2 Kings, so unless my abacus is completely out of battery power, he has shown 14 hcp, leaving him a possible 0-2 left to go.

crunch the numbers to see! it is essentially 1/3 that partner has the ♥Q now you need the probabilities that he has 2,3,4,or5 ♥ but no Q(if that is relevant)

Texas then 4NT is the standard way to set trumps and bid keycard.

Jacoby then 4NT is quant with 5 trumps.

Please edit the original hand since I think there's been lots of confusion about what was actually held based on some of the replies.

Assuming this is really my hand, I will convert to 6N since I can count 12 tricks. (5 hearts, 3 spades plus AK, AK in the minors) and be happy.
