3NT

While it is true that 2 is probably going down some number of tricks it is also true that we migh have a slam or grand slam in this hand, pd is unlimited so passing 2x is too unilateral. If pd has a big hand with clubs, diamonds, or hearts with a singleton in spades then all my values will work.

With a big hand pd will bid his suit over 3NT and I will be happy to cuebid.

the only plus you're likely to get is pass. And that's not even the weakest hand pard can have.

True, but pd can also have a hand where you are cold for 7

Indeed. But which is more likely? The above

I'd say the first... but if you feel lucky, by all means go for the grand :)

Whereeagles, I don't have the answer to the question, maybe somebody can run a simulation to determine what is best.

 

My reasoning is:

Pd might have:

1- A light takeout double with shape (as you posted)

2- A very strong hand

3- A balanced hand with 13-15 hcp

 

With 1 you have to compare 2x vs 3NT probably 2x wins some imps in average.

With 2 when comparing 2x vs 6x or 7x you will lose many imps

With 3 2x vs 3NT is probably close in terms of imps

 

Then if we compute how likely is 1,2 and 3 we can determine if pass or 3NT is better in average. I have the feeling 3NT is better because it covers the following scenarios:

 

- When pd has a big hand you can discover a slam or grand slam

- When 2x makes you are not in the tragic 2x

- When 3NT makes and you can't get a lot from 2x

 

But as I said I won't claim pass is wrong and 3NT is right a simulation will give us a better understanding.

Partner has doubled so why not help him by describing our hand to him..

 

We have s double stopped, we don't have 4s, we don't have a long minor and we're better than 6-9 oh 3NT accomplishes all in one bid guess I'll do that then...

 

If partner has a big hand then he can go further ( I suspect not as RHO didn't continue the barrage in 3rd seat)...

I pass, but not because I think it's the right bid.

 

Down by a bunch, we are searching for swings. I suspect that 3NT is the "normal" contract on these cards. If it's not, then partner probably has a light balancing double and we're more likely to win by defending (nick 2 a trick or so) than by bidding.

 

Passing produces a swing if the weak two bid wasn't opened at the other table, or if the player with my hand at the other table chooses 3NT (which may be a more normal, or even more successful percentage-wise call). These swings are roughly equally likely to be wins or losses... so state of the match dictates to take them. Passing is more likely to produce a swing board than bidding.

:lol: Pass, but imo it is close.

RHO is odds on to get at least four spade tricks: +1100 for us versus +1390. With one outside trick, is +800 for us versus +1370 (assuming it is bid at the other table). With two outside tricks, it is +500 for us versus +630ish in game. All the foregoing situations favor bidding on, but I need a favorable swing, and +200 or +500 versus -100 is just the ticket. It is also, by far, the single most likely outcome.

 

Further, the contact and/or play at the other table may be suboptimal. Take the sure plus and run.
