You are all in the right track. But what happens when West covers with the A the first round of ?

Incidentally, what is the a priori probability of West having both honours (knowing that East does not have them both)? And what is the probability of West having them both after he played the A?

Four trumps.
Two outside aces.
A useful void.
A good five card suit as source of tricks.
Never support partner's suit.

This seems to be not so unusual in BBO.

Thank you to all that answered and commented so far.
I will wait one or two days and post the actual hand so as to see how different decisions would have fared.

This is a nice problem, as the “obvious” solution that comes immediately to your mind is not the right one.

And it is not because the problem is ambigous or incorrectly stated; it is because your mind think it knows both the problem and the answer and does not really think what is written but what it has already decided. Never happened at the bridge table?

To make my point, think at the problem stated in this way: imagine we have to gamblers whose strategy is to try to win two times in a row, so that when they win one time they bet all the winnings the next roll. One of them is trying to get a 6-6 sequence while the other a 1-2 sequence. If the game is fair (i.e. the house pays 6 to 1), which strategy is better?

Obviously this is a zero-sum game, so there is no strategy that can change your expected winnings (or losses). Maybe this is the question you thought you were answering.

Does this contradict all the comments regarding the posted problem? If you think about it for a minute (how the bettings would develop), you will see that it does not. But to be fair, I cheated since I did not state the conditions of this other problem in a clear way.

Without really bad breaks 6 should have many chances; if partner cannot complement my then I may be able to ruff one.

Of course, it is a bit a shot in the dark as he could be something like 8-0-4-1, but if that is the case we may even be down in 4.

The situation is terribly fuzzy because the range of hands that North and South can have (both in terms of HCP and distribution) is very wide. North and South know very little about what the other has.

But with the hand you show it would be too lazy (and bad bridge) for South to bid only 4. That hand should be something like 4 or 3, but not a simple 4.

Apologies. You are right, I did misread the problem.

Sorry, I meant 1 5 3 then 2 (which is in position 1) then 4 (which is in position 5).

You start from the edge but do not go 12345 … try 1 5 3 2 4.

If you start from any of the edges and misguess then the dealer does not have a choice if he does swap it with an adjacent card.

You can ensure to find the lady in 5 tries with equal probability, so your expected average is 3$. Which means the player will most probably end up with a small gain (and the club with a small loss).

This assuming that the deal is actually random, and assuming that ending with a bunch of club pens can be considered a gain for the player. In any case, it would be a loss for the club.

The strategy is not to difficult … start from any of the edges.

Or unless West is good enough to play the J from AJ9 or KJ9. Classic false-card in the books, as always not so easy to find at the table.

Sorry I cannot confirm, but could be. My friends played it in BBO, so they may have chosen that VuGraph archive file.

Yes, this in indeed the right line; and for the record clubs were 4-1 with North having 4. What I found interesting is that the hand is another example of how often cashing your tricks operates a squeeze in an unexpected way (here South is squeezed out of his potential threats).

I would have said 2NT is VERY unusual with those cards …

Thank you for your answers. For me it seemed equally clear to pass, and opp 4NT at the other table looked a bit like lunacy. However partner had -,QTxxx,Jxxx,KQxx so both 4 and 5 depended on a red queen finesse. Both contracts went one down, but both could have made with a slight change in the opponents hands.

As far as I know, the standard situation where the bid means “we have 9 tricks if you have spades stopped” is as a direct overcall, i.e. (1) - 3.

Well, first may be is not so standard and second a more precise definition should be “we may have 9 tricks if you have spades stopped, and they actually lead spades, and they do not make a nasty switch after that”.

Edited: seems already commented below … I should be a little less lazy and read all comments.
