So transfer to 1N can contain balanced invites with no 4cM both weak, inv and GF or GF hands with exactly 4M and longer diamonds.

2♥ was a reverse, and 3♣ described as 7+. Was three clubs game forcing? Can I assume that 4♦ in addition to being a cue-bid (as described) is also much stronger than the implied 7+ earlier? Since with a diamond control, partner didn't bid 3NT in case we were weaker and looking for 3nt?

With the above assumption, six clubs looks like a minimum spot. Six notrump (at matchpoint) is in play, and even 7C is possible xxx xx AKQ JTxxx. I think I try 5♥ here although I don't think that will get us grand relieable even when it makes.

Can partner have a 4153 hand?

He is either balenced no 4cM or 4M 5+D, if the former then has he denied a spade stop with 4♦? Or would he cue here if slam interested and could still hold the K♠/

I would bid 5h regardless, 6♣ is a minimum for me now.
If he fails to bid 5♠ I'll play 6♣ if he bids 5♠ I'd like to try 5NT as a "I'm not finished, do you have more to say" bid but I still need him to have 5 losers covered, Ks covers one, Ad covers the second, the KD would only cover the third and I still need to get rid of 2 heart losers. So over 5♠ I'll bid 6c and if he has the world he can kick on.

I bid 6C now. I think that partner has shown a extras by bidding 4D, so he has considerably more than a 7-count. It is certainly possible that 6C is on a hook. It is also possible that it is a bit better, or completely laydown.

I don't think that we should try for a grand slam. It's true that if we bid 5H we can't have much more than this in terms of HCP or shape, but I find it hard to imagine a hand for partner with which we want to be in a grand slam and he wouldn't have jumped to 4C or cued past 5C.

I'm not sure I am drawing the correct inferences, but it seems to me that responder has denied the 4M-longer ♦ hand, so is known to have an invitational balanced hand with no major (I am reading the 4♦ call as showing a non-minimum for the auction to date).

He can't have, for example, all of the ♠K and the ♥Q and the diamond AK and the club J, since that is a gf. I'm not saying that grand is impossible, but I am saying that it seems speculative and difficult to get to no matter what I do now.


For one thing, even if we have NO side suit losers, he might hold xxx in clubs and now grand is at best borderline.

So I bid 6♣.
