Reported by Alan Sontag in “The Bridge Bum”…. also the first place I saw Robert’s Rules in print.

That suggests that the responses over interference are best structured in such a way that responder won’t pass a hand that would act over a non-precision opening bid and interference, does it not?

No matter what ranges are assigned to actions over RHO’s initial double (I think 0-5 is awkwardly wide, but that’s just me) reevaluation and upgrading/downgrading is critical. Whether a queen is well or badly placed isn’t likely to change whether a 16-HCP hand is suitable for a 15-17 1NT opener…. but it swings the value of a 4 HCP hand by 50%.

The south hand is just plain too good to make the same call that you’d make with Kxxx,xxx,Qxx,xxx.

You meant “teammates for ex-Columbus”, did you not?

> I don't see why ACBL should be blamed.
The question is not whether the ACBL should be blamed, but whether it will be blamed. It will.

> Have there been any peer-reviewed evidenced-based studies that confirm that playing cards….?

Not that I am aware of, but many years ago I found myself playing at a local club game with someone who was considering doing this as a thesis topic. She was considering specifically pairs movements, which are designed to maximize the number of people who handle the same thrteen cards.

Face to face play with tablets is possible in principle - give everyone their own deck of cards, they make up their own hand at the beginning of each board based on the tablet display, play in the normal fashion, hang onto their own cards and repeat on the next board. That's how DOOP worked, and it's surprising how easy it is to adapt - you just don't put your cards back into a duplicate board when you're done.

Of course in practice this isn't going to happen at a NABC that's just two weeks away.

A duplicate bridge event is unusual in that the participants will lovingly fondle a collection of thirteen sample swabs for several minutes, then pass them on to someone else who will do the same…

Other coronaviruses are known to survive on surfaces for days, so I’d be concerned about transmission through the card handling, both within a round and across events.

Sit to the left of your strong opponent…. and coach your partner to preempt aggressively.

This is pretty close, but at matchpoints do you want to be in a 25-at-best 3N with a hand this flat?

There’s no reason to think that 3N won’t make and no reason to think that 6C will, so no reason to move over 3N.

Fair enough - this hand is just a microskosh under this partnership’s requirement for an opener.

More often a balancng 1N is coming from an unpassed hand

> So what happened?
I leaned a lot. Can’t speak for my anonymous collaborators, but I’d bet they did too.

Many many years ago, back in Usenet days, for a while I was part of a group of intermediate players collaborating on the MSC. The collective did MUCH better than any one individual within it: no one’s initial set of answers would have scored better than the high 600s, but the consensus after arguing over the ones we disagreed about consistently came in close to 800.

This experiment was inspired by a management training exercise on how to set up effective collaborations. The key was the discussion and the opportunity to reconsider initial thoughts.

Terence Reese described this play in one of his books… of course it works in the book. The only time I got to try it, my partner as dummy knew exactly what I was doing but RHO with both aces didn't count the spades and assumed that the trey was the last one because “a lot of them had already gone by”

Yes, and if I had chosen the winning one I mght not have posted the problem :)

But I am curious - what thought process swayed you to the diamond ace?

I may not have been clear. The way the show was run, the host did not open a door randomly, he randomly chose whether to open a door that did not conceal the prize or to open no door. Under those conditions, switching when he does choose to open a door is 2:1.
