bid on?

Red at IMPs? Why am I still thinking? I don't really expect this to make, but on a good day it will at we're certainly getting sufficient pot odds with the punt.

I see this a lot. Something is wrong when both partners look at the vul and form of scoring. There should be a "push seat" with the other bidding straight up and down. The problems occur because partnerships are never sure who is supposed to be pushing.

Yopu know the sort of thing, 1NT - 2NT - 3NT that turns out to be a "good" 15 opposite a "good" 7, with both citing "vulnerable at IMPs"

It would be good to have guidelines, which suggests a poll.

Who do you think is in the push seat in this auction?

both players must bid to optimize the imp expectancy. the imp expectancy depends on partner's tendencies. of course this is a feedback system, it will need to be calibrated continually over time. the adjustments will be poisson processes (partner's catastrophic acceptance on that random 15 count :) ). it is not easy but it is pretty simple in theory.

This is a good question.

 

I have always thought that the first player to limit their hand should not push. They just accept a game try with an above average hand and refuse with a below average hand. So for example after a 1NT opening only responder pushes and after a single raise of a major only opener pushes. Otherwise yoyu do end up with those silly situations where a 1NT opener nearly always accepts an invite. But if neither hand is limited you can each stretch by half the total amount that is justified.

I am wondering whether, on interpreting the simulation, you should consider the possibility that the opponents are close to doubling, and will double 3N when they would not dream of doubling 2N. I venture to suggest that if they do double then you should assume that the contract is failing.

 

This may point in favour of passing the 2N, although personally I play 2N rebid as 18-20 (and therefore forcing) rather than 18-19, so it is not a judgement problem for me.
