EDIT. Please ignore. Tricked by the lead into thinking its there. So let's change the question. How do you check if grand is there or not. 17-20 is a broad range

With reasonably accessible methods and guesswork

Ignore EW. Honestly can't be bothered to use the hand editor

I think it depends on the lead but it is sure on every lead. Scrub that. You still have to play it right. Just happened to get a friendly lead

I don't think so. I think it goes 1NT-2♣-2♠-4NT-6NT.

[AL78]

I don't see it happening in UK Acol weak NT land. 1♠ - 2♦: 2NT (15-17) - 6NT, and even that would require the NB to recognise they have 32-34 HCP combined so are in the slam zone.

I don't think there's much wrong with your auction, although I dislike the style of responding 2D with 4 cards. For me it's too strong for a 15-17 1NT.

[thepossum]

I was hoping to find if partner had max
If partner has 20 its there
Ignore that it was a best hand tourney
Imagine you hoped north has max

[thepossum]

Thx 😊

[thepossum]

The 2D was kind of best minor gf

[thepossum]

Sorry about slightly mis wording the theme

I was curious about how to explore from both sides

Clearly I couldn't get the information to know one way or the other

Sorry about all the dupes. The forum goes weird sometimes

Sometimes I have a question while sitting at the table and by the time I can post it a day later I have forgotten my thoughts

My thoughts were as South that it seems a possible grand. How do I find out

Not even totally ignoring the best hand aspect could you explore suits and high honours enough

I was rather upset at a negative IMP because I thought I bid ok

A lot of people play the 2N rebid as balanced 15-19, this is particularly important in the style where you play 4M4m32 hands open 1M so you can find the minor suit fit.

I think this hand is too strong for a 15-17 NT so would open 1♠ anyway, but I don't think the S hand can do any more than invite grand if that opposite 17-19 bal and partner will decline it.

You have 2 bal. hands with a combined HCP count of 34.
You have 12 top tricks, and you can make it, by finding the Queen of hearts,
you have a 2-way guess, which basically means, the grand is 50%, not enough.

Perhaps the Yellow Rose of Texas can help

1N-4♠ 2(443) 17-18
4N tripleton?-5♣ 2443
Now it's up to North to judge the correct contract and perhaps the ♠ holding swings in favour of 7N. There may also be additional bids after 5♣ which can ask for specific cards.

[Cyberyeti]

The interesting question for N/B, is if you make the south hand any of these where there are 13 top tricks, can you bid it:

K10
KQxx
Axxx
AQx

K10
Kxxx
Axx
AQJx

K10
KQJx
Axxx
Axx

Which is why I bid 6 and was slightly peeved to score negative

Ignoring the fact I knew we had 34 max was 5nt quant ok

I didn't word my question well. It was more along the lines how each partner can approach the hand

After winning a non-heart opening lead and cashing the black suit winners watching the discards, I wonder if it is possible to deduce that one opponent holds the ♥Q and ♦Hxxx and is squeezed?
