Jim, The two chances should even out across both layouts.
i.e. If Jxxxx of spades suggests a 1H overcall with 55 int he majors, then the case would be same with a 65 shape.

I personally do not care that much about exact honor location on shapely hands. Of more relevance is total hand shape and total hand high card range.

If someone can point out a simple way of computing expressions like 6C3 using verbal logic, thatd be appreciated.

A very unusual look at a fascinating situation. Enjoyed the write-up.

Henry, not sure about the 5512 shape comment. Declarer is intending to cross to a spade and pay out to the 6-0 spade split than take a big view in trumps.

Kit, i think its incorrect to count the 4-2 splits as equivalent to the 3-3 (after discounting the HKQ). That is effectively saying that West's 65 shape is as likely as 55 if not more.

We need to look at original likelihood to compute the cases for the 6-2 heart distribution. Ignoring the HQ should be fine for the 5-2 odds calculation but not for the 6-2 break.

Am aiming to publish the detailed followup to this tomorrow.

My claim is incorrect.

If the defense gets in a heart trick and shifts back to diamonds, declarer is dead.
On the H8 switch, declarer rates to play either the Ace or the Queen. If partner can switch back to his own suit, we score five tricks with two clubs, two diamonds and a heart.

On the HJ/H10 switch, declarer may find the winning option of rising heart Ace and guessing correctly later.

I was affected by the hand record bias, after all !
Now comes the bit about analyzing declarer's line of play (considering AQ9 gives him no guarantees). Was that best ?

Very well written piece. Enjoyed reading, if only as a reminder to not cut it too fine !

3 invitational sounds great in theory but partner is very rarely going to deliver four hearts.
We should clearly have doubled 2 to stay in the hunt for game. Guessing aggressively so late in the auction, in the face of ambiguous information, is risky.

Very anti-establishment. Can work out very well or very badly.

Thats a good point about presence of diamond queen making the defence easier to find. Enjoyed the article.

All conventional actioons should be alertable behind screens. Most players would agree and its an easy enough change to any regulation.

While some players “ask all the time”, most of us do not. Nor should we be required to. The alerting regulations should be based on simple principle of natural-if-not-alerted.

On the subject of screen behavior, my pet peeve is people making a sound with their bidding box when they draw out their bid. Its quite clear on the other side who was thinking when its the same guy who makes the noise.

Thanks James. Is it possible to do a similar exercise for BAM scoring ? I suspect the total number will have a large reduction.

Thanks for the comments and links, especially the Goldsmith study. It seems that 0.25 imps/board superiority (quite a significant edge) leads to 69 percent certainty of winning a 128 board match.

If my interpretation is correct, then the final of say the Bermuda Bowl or US team trials should ideally be longer.

There are two teams. Team A and Team B. One is stronger. How many boards do we need to find out with reasonable confidence. That was the intention of my question.

Thats a good point about avoiding blindly following opponents' signalling. Recently,playing 4S, declarer held J7 in hearts opposite Q32 in dummy. LHO had made a weak jump overcall in hearts and led the HK (for reverse count). The correct play would be to randomize play if they follow with the 4,5 or 6. But when they play the 8,9 or 10 we need to play precisely the seven.
