I've heard bots have a nice game in one of the data centres there each Friday, but I am not sure which one. I would ask “Robot” on bbo. He's usually logged in at the top of each hour.

Dave,
If the auction goes 1-3-4NT-5(0/3)-*hesitation* 5- 6, you would still roll it back to 5?

Richard,
I recently re-visited Kelsey's Advanced Play at Bridge (great book BTW) and while it does not focus on the defensive principles at large, it contains several examples of defenders using quite outdated signalling principles. The book was published in 1968.

There is at least one hand that E might hold where diamonds pitch is relevant: KQxxxxxx xx x xxx. This makes playing the clubs from the top more favorable for declarer. So E can influence a S's line of play if psychology isn't a factor.
If I am E and S is a world class robot declarer, I am pitching a diamond with qxx and spade with xx.
That's my take on a. If you agree with me on this, does this change your answer on question b?

David,
The first question I would ask myself after seeing that pitch would have been: what is Bob Hamman's perception of me as a player?

Big names put regular players under spells.
A friend of mine played a match against Barry Crane.
Early board of a long match. He was in 7 of a suit holding Qxx in dummy opposite AJTxxx, Barry was his LHO.

He rode the Q from dummy and it held. Played a low one and a RHO followed. Then it occurred to him that had Barry started with Kx of trumps, he could have played low just to cause an irreparable psychological trauma to the declarer. He played the Ace and went down 1.

So let's say you hold AJT in dummy and K9xx in your hand and you know this suits breaks 3-3. your LHO pitches a diamond and you know he had other pitching options. How does it affect your chances of finding the queen on your left?

Robert,
So if you can pitch from Q432, why can't you pitch from the 432 holding?
And if I am playing against you and I see a diamond pitch, wouldn't I have a marked finesse against you?

Michael,
E:
KQxxxx xx xxx xx
KQxxxx xx xx Qxx

a) Poker aside (just bridge), and let's make it pure: S & E are experts, know each other's qualification level, E does not believe in psychological aspect of the game.

With which hand E is more likely to pitch a diamond?

b) E is Mike Lair, S is Zia, Everything else is the same. Including the question.

c) In a vacuum - with ALL possible hands E can hold that are consistent with the bidding, does pitching a diamond have a positive EV, 0 EV or negative?

Robert,
On this deal one glance at the dummy should be sufficient to ensure that a diamond pitch is safe.
Regarding the 432 holding. Are there situations where you would pitch from the suit if your holding was: Q432?

I don't think you thought about what I wrote very carefully. It's not about counting tricks or trying to convince anyone in anything.
A spade pitch - from the psychological perspective - is very neutral. It's designed not to reveal any information to the declarer. You're known to hold spade length. Spade pitch can't damage you. You know that, declarer knows that, and you know that declarer knows. After trick 3 declarer has exactly the same information as before trick 3 and his line of play should not be affected by the pitch.

A diamond pitch is different because it's “not neutral” on surface since it can affect declarer's line of play, therefore my question, as a declarer, is why East didn't pitch a diamond. Kit writes something similar above and states that a diamond should be pitched regardless of what East's holding. Once a diamond is not pitched, that makes a spade pitch a tell.

It's not a strong tell by any means, sometimes a cigar is just a cigar, but it does change the balance of the hand a little.

Poker player have tells and good players are well aware of their own exploitable weaknesses so they are trying to suppress these tells. But sometimes that suppression is a visible effort itself and if an opponent catches it, (s)he might realize that it is an attempt to cover for something.

It's not a bridge thing it's a poker (human psychology) thing. Pitching a diamond might incline the declarer to think that E had started with a short diamond holding, therefore having some club length. That's the direction of thinking E wanted S to avoid. Interestingly, if that's how Zia reads it, he would be more likely to finesse against E.

I don't know if he is so great, Dave. He did ok guarding Jokic in the Conference Semi-Finals, but against faster Warriors he was pretty much useless. And he's not an offensive threat by any extent.

As per the play record, only two rounds of s were played by the end of Trick 5.

Gary,
My opinion, based on what I just have read in the bulletin, is that you pretty much gave up on the play (the “I'm toast” remark). Declarers in that mental state often just submit a losing trick ASAP and claim the rest. I've seen this multiple times. What I've seen less frequently is how a declarer regroups (as you suggest you would've done after discovering that N started with xx) after receiving a new piece of information.

If queen-ask response does not reveal anything about the kings (like in this sequence), next step would be the King ask (specific or total# based on your agreements).
If that “next step king ask” bid is skipped, the bid becomes “the ask”.
Since the “kings” question was never asked, the asks are about the 2nd round control (had W asked for kings, that would've been the 3rd round control on the following round).

Had East held AKxxx of clubs instead of AKQJx, the standard response would have been 6 (2nd round control, 2nd round control, no spade control), however the correct bid with this E hand is 7d, showing a side source of tricks.

Very similar auction, the 4 bidders claim that the hesitation before double 4 made 4 more attractive, not less :)

Since the hesitation can make the pull more and less attractive at the same time, I suggest we dub it the Schrodinger's Hesitation.

I am not sure hesitation makes 4 more attractive. Quick double would deliver the information that the hand is “pure” (either take-out or penalty or very strong - subject to their agreements).
Also, for less experienced players there is a possibility of “is my partner going to understand this double correctly” type of hesitation.

Here's one hypothetical line that, actually, makes 4 more attractive - partner is probably is not strong enough to make a quick dbl -> I don't have any defensive tricks -> But we have massive spade fit and favorable vulnerability".
