4NT is quantitative, there's no reason to think ♦ is the trump suit. If West has ♦ he can bid a simple 3♦ after stayman, which is GF.


I knew diamonds were not agreed, I assumed that was what p had in mind, a dumb logic there I know, but I had to think something

Also I would like to disagree with a statement made about beginners and intermediates, I actually seem to have this issue a lot with BBO advanced and Experts,

I would just like to understand this seeminly easy convention, that apparently is not, even though I have a bad habit of using any excuse to bid this convention

Fortunately here, as so often is not the case, you have little care whether PD has intended to respond aces or key cards ! You asked him to bid 6NT with a max, and he's responded 5 probably misunderstanding that you meant Blackwood of some type, or perhaps playing it safe, saying I am accepting the invite to 6NT but responding as RKC just in case that's what you meant !

Off course Quant is "standard" after 1NT-2-2 and PD may even know that, but may not be sure that you know that so he plays it safe, and assumes that you may (weird as it seems here) be intending RKC for the last suit bid when none was agreed. In that sense his 5 costs little since since there's no chance of playing it there.

Now from your side and hand, you don't care whether PD has shown 3 aces or 2 and the Q as you have three or four aces combined and aren't interested in a grand. So play it safe, since if he was certain you meant Blackwood, 5NT may be asking for Kings and sad as it may seem, lets him bid a grand with an undisclosed source or tricks. I wouldn't expect that to happen, but I'd just bid 6NT in your seat after 5 as you seem endplayed into it. After your 5NT, PD didn't respond kings, perhaps realize you two were both confused as to what the sequence meant.

If this is a regular PD, I suggest that you discuss Quant NT's and also how to ask for aces or keycards while using Quant in these sequences, and "yes" forumers Gerber for aces does occasionally play a roll in these sequences.


Sorry for the long post, but just trying to stress the need to not panic when the rather uncommon sequence seems ot may have confused PD. Just get to 6NT here after 5 as that's where you want to be anyhow.
