To generalize (perhaps overly so), in my experience the bots do not do well at ranking which plays to make. In theory, they should know the difference between a mathematical lock and a play that is likely good from a simulation. So they may take an inference that a suit is going to split 3-3 and block another suit, then cash out the 3-3 suit. Often it makes in those situations, although it had another actually guaranteed way to make.

In this situation, the bot probably decided that East always had 6+ clubs, because that is what it is programmed to think. However, it should be embarrassing to BBO that they still have bots lead stiff kings of trumps on opening lead and play queens/jacks of trumps in defense not in 4th chair. Yes, there are places where certain falsecards would be correct, and BBO in theory could have a bot that is actually “good,” but just making those hard overrides would save a ton of tricks when it plays randomly.

@David Burn

Your beer comment is about 20 years stale. Yes, perhaps a few bars in the US still serve awful beer, but I'd wager that even you would find the quality and diversity of American beers to your liking. Sadly, most of the best ones probably don't ship much overseas. Some don't even ship to all parts of the US.

Federal Jacks, regardless of the provenance of its brewer, is not even the best brewery in Maine. That honor would likely go to the Maine Beer Company, purveyors of such brews as Lunch: https://www.beeradvocate.com/beer/profile/20681/68916/

If South covers the spade at trick 2, you don't need to do anything. You just get 3 spades, 4 hearts, 1 diamond, 5 clubs.

Record whenever someone makes a deviation from their stated 3-point range of at least two points.

Probably just marked a partial in the wrong direction.

He will never play Q then T. The others are all plausible from either holding, so what matters isn't the order but just the combinations.

That's how they trap you! You think, “there's no way this can a trap, I don't have to bid, they must be on the wrong page” and then next thing you know, you've raised a level to jam them, and…

The easiest thing to do would be to stop after round 1 (or whichever round this was discovered), have each table take their aces of hearts out of each board (without showing which pockets they came out of) and have each table distribute aces of hearts to the properly colored cards at other tables. It would probably have taken about two minutes, and no information would have been shared between tables and everyone putting the aces back would already be authorized to know where they went.

Regardless of how the beginning went, at trick 11 East knows that North has no more clubs and no more diamonds. He might have another spade. If not, he has all trumps and West will never gain by ruffing from a 2-card suit into declarer. So the only possibly useful thing to do is to play a spade and hope that partner can ruff it. This works without having to go back and think about the bidding.

When given the hand, I described the J from Jx as a play that is only possible from a player who knows enough to consider it but not enough to know that it's crazy.

If you cash the T, you're afraid when West was 6-1-1-5. When East pitches a club on the fourth diamond, you don't know whether East has Kxx, xxx, or any four clubs and will have to decide at some point whether to finesse the club or play for 4-4 clubs. You should probably play for 4-4 clubs in the case, but you don't need to.

Playing a diamond and forcing an early ruff and ruffing a spade back is equivalent to cashing the heart ten and playing a diamond pitching a spade, on which trick you magically force East to pitch a spade if they have one left. This turns the 5-3 clubs problem into the 4-4 clubs problem.

This is equivalent (on a different hand) to entering dummy to ruff some suit to ensure you create a threat rather than running trumps and allowing the opponents to discard whatever they please.

I'm going to assume we don't have any special agreements such as the one Steve Bloom points out above (partner being able to show shortness below 3 after a 2 signoff) because I would expect that the OP would have specified this. We can't impute our favorite partnership agreements on this situation, nor can we decide who partner is, what their ethics are, etc.

You can always call the director after seeing dummy and playing the hand out. The protection for the opponents will be the same (strain won't change) and you'll actually know what happened. You'll also create maximum damage for an ethical lapse if you bid 4 now, which is what your partner deserves if they did something wrong. Until that point, the best thing you can do is to assume you were playing with robots. Had you bid 2 and the robot made a second (if clumsy) try, you'd bid game. So bid game and look for damages later.

As the 2 bidder, one thing I know for sure is that had I only discussed 3-card and 4-card Drury and no additional passed hand good raises, were my partner to not alert 2, I would bid according to whatever plan I made initially. Presumably when I decided to bid 2 I had a plan if partner bid 2. If my partner decided to mastermind active ethics after 3 because they decided I was either unethical or ignorant, I would either choose to punch them in the face, never play with them again, or both.

Carol:

Wolff signoff is a convention whereby responder's 3 bid forces opener to bid 3, after which responder can place the contract, either by passing 3 of rebidding their original suit. (There is a question as to whether:
1m - 1
2N - 3
3 - 3
should show hearts and a weak hand or be something else. Either way, continuations of Wolff signoff higher than responder's first suit should certainly be forcing, since there is nowhere else to sign off. Personally, I like:

1m - 1M
2N - 3
3 - ?

3oM (other major): at least a mild slam try in the unopened minor
3N : mild slam try in opener's minor
4 : strong slam try in opener's minor (even if it's diamonds)


Since 3 contains the hands that are either signing off or have given up on playing a major suit fit, 3 is available as a checkback bid for the majors. 3M directly is also available as a forcing 6-card suit, since responder could have signed off by looping through 3-3. You should agree whether after:

1m - 1M
2N - 3
?

opener prioritizes:
a) showing 4 cards in the other major
b) showing 3-card support for responder's major
c) showing a useful number of hearts (3 if responder's suit, 4 if not)

and you should also decide what you think responder's bid of 3oM should be over 2N.

Whether or not transfers are good, I don't think this comment addresses the OP's question in a way that will help them.
