2♥ was alerted as weak, 2 NT natural, 4♥ was texas, 4NT was alerted as minors. Its an online partnership and not much agreement over 2 NT overcall except than "system on" EW system agreements; xfer followed by 4 NT =quant , texas followed by 4NT=rkcb. 5NT in competitive auctions = choice of slams.

What went wrong, if any, and would you wanna be in grand ?

[Fluffy]

doubling 4NT didn't help your cause but I wouldn't wanna be in grand, I mean if grand is bidable with AQJx opposite singletong, then west might just as well drive for it after 2NT.

Doubling 4NT suggests defending, with now 3 cuebids avaible you should make one to move forward. With no agreements you can just go for 5♣, with an experienced partnership I use 5♦ as shortness looking for a fitting hand, that would get an easy negative from East and I'd settle for the small slam.

Things went fine until the very unexpected 4N. I don't care for the double of 4N - this should promise more of a willingness to defend which is not a good description of a 7213. I don't know why East didn't cue 6♦, but other than that things looks OK to me. You have an obvious typo in the bidding diagram.

Even after 4N, I do not know if I want to be in 7. Where are the points for the weak 2? There's no certainty the ruffing finesse is working; it looks like 5:3 which is thin for a grand.

I am not sure if we shd be in grand either, but only reason grand was not bid because West did not know if pd had 2 aces, my question mostly was about 6♥ bid, as Phil said west did not bid 6♦, does 6♥ guarantee ♦A ?

@ Fluffy; if 5♦ meant "pd i have ♦ stiff" , it would be great, but 5 level cues are mostly 1st round controls rather than stiff, especially when RKCB toy is taken away by opponents.

About the play, i think if ♣ is not led, we almost have a claim in 7, since N skipped 5♣ bid and preferd ♦, regardless of who holds the ♦K. (assuming S has at least 6-5 minors for his bid, even if he has 5-5 KQxxx ♣ will be enough)

12 quick tricks is too much to ignore grand for me i guess

Sadly south is on lead, so the club lead is quite likelly when the squeeze works.

As I said, I use 5♦ as shortness when the opposite hand is limited and we had no space for splinter. A kind of last train, but this is my agreement you can have yours .

If worried about the 2 aces for grand I also play a neat convention wich asks for keycards when we are at the 5 level already: 5NT, again this is only my partnership agreement, and I don't think it is standard.

West's 6♣ bid bypassed hearts, so West has denied heart control. When East cooperates, therefore, he promises heart control. East's bids here mean:
- 6♦: I control both diamonds and hearts
- 6♥: I control hearts but not diamonds

Is this auction sufficiently informative to choose Dx to DQ OR DA DQ ruffing finesse?
At least high confidence to get that right?

I say YUP. 7S.

True, but original deal he had QTxxxx♣ and Kxxxx ♦ x and x in majors

2♥ opener had xx JT9xxxx xxx K, they led ♥ and pd made 7 by finding the ♦K
