Hi all

I was rather lucky with this because I miscounted. Maybe some perceptual bias
After the result I thought I would check Mr Pavlicek's hand evaluators which gave an interesting range too - although I accept much is biased towards suits




I thought it was worthy of 2NT, because I miscounted it, but still do
You will never guess where I ended up :)

Sorry you are second seat. East has passed but we are red and they are not

Hi,

the hand is certainly worth an upgrade.
If you play 2NT as 20-21/22 go for it, ...
I would not upgrade by more than 1 HCP, but assuming I did not miscount,
you happen to hold 19 HCP.

In case p asks for min / max. you are min.

With kind regards
Marlowe

Thx, sadly I upgraded it so much I ended up in Grand on a quant
But I knew I was stretching it by a point - but at least I thought it through. What could partner have. Where are my weaknesses. I hope for AK spades etc - it had given me a spade transfer followed by the quannt - my partner claimed 13-15 and long spades :)
Do any of those hand evaluation methods listed by Mr Pavlicek work in NT - they ranged from 19-21 - I am curious about the different methods
But whatever, thinking I had 20 I upgraded it to 21 for the quant :)

PS Is there anyway to check for aces and kings after 5NT quant



I may seem tobe making light of NT hand valuation with a serendipitous outcome but does anyone have a reliable method
And please don;t ask me which world of bridge me and my partner inhabit where 35 or 36 is sufficient, when you are lucky on average -, sorry 34 upgraded by a point. I cannnnoot give you my stats on 7NT-1. Usually partner error. Missing an Ace would be so sad

Elegant bidding by GiB for once. You have only to refuse the grand slam invite and correct to 6NT, you have a minimum for your bid.

I did say that my accepting of the grand was due to counting error and an upgrade, and possibly dubious freasoning where the missing honours could be :)
I also figureed GiB would not invite to grand with no controls and minimum ;)
I even ran a sim and it was around 65% so not really good enough, except in a meaningless tourney - but trust my partner to have the max and it goes up to around 79% :) I know most like to have even more certain with their grands but I enjoy the rush sometimes

So yes, counting error, wishful thinking whatever
So given that the hand calculators on Mr Pavlicek's site rate it anywhere from 18-22 etc
I know this is NB forum and doing anything other than counting your points is a bad thing to do, and if the hand had any importance or dollars riding on it :)

I rate the the south hand as 27 Banzai pts (equivalent to 19 in hcp). However, this doesn't solve the question about is there 13 tricks, or if you should open 2NT.
Ultra Relay: see Daniel's web page: https://bridgewithda...19/07/Ultra.pdf
C3: Copious Canape Club is still my favorite system. (Ultra upgraded, PM for notes)

I disagree. I am OK with the 2NT opening, I think it serves the hand well. But it is borderline 2 opening with a 2NT rebid.

Now partner is telling you "Hi, re-evaluate your hand, and especially take notice of what you hold in " (that is the reason to transfer rather then ignore them and bid 5NT right away)

Your hand HAS improved further.

And I disagree, to put it mildly.

Partner invited on a quant basis, this means purely HCP based, the shape information says nothing, that the Kings partner has,
are the Kings that you need. Replace 1 of the Kings with the heart King and the quality of the GS goes down.
You stretched with your opening bid, the development of bidding means, that you dont need to have regrets that you did strech,
but you need to remember / keep in mind, that you did.

This does not mean, that the GS cannot be found.
The trick is setting trumps, asking for KC and asking for Kings, and if you have the tools, you will find out, that all
the Kings you need, are there.
