This is a pretty ugly 2♦ bid, I would much prefer it if GIB would bid 1NT with this hand.

You think the 2♦ bid is ugly. Guess what the bot thinks of the 1♦ bid?
You must know the rules well - so that you may break them wisely!

or the pass of a forcing bid for that matter. But I agree, 1NT is probably better although a notrump contract might play better in the South hand.

I dunno, you tell me. :P

I do this all the time in robodupes, BTW.

absolutely, as should many people, which is why I have issues with robodupes == bridge (especially the L40 implications).

Don't knock it, it's a great game, and does require a lot of skill, but "engineering misdefence by psyching 30+% of hands" isn't my idea of a "bridge skill".

I'm not at that level yet. Do you guys have strategies for how you psych the bots?

I recommend experimenting a bit.
I don't think that "real" psychs work that well, ie according to the legal def (by which I mean GROSS mis-statements).
But slight variations seem to have a reasonable effect.
One common method is to open the weaker minor and hope you don't get to play there. Not something that you can do in a human game too often due to the implicit agreement arising.
Another is to open or rebid NT on slightly off-shape or (perhaps less successfully) off-values hands.
One of my favourites (there is an earlier thread about it) is to lie in response to Stayman. You would not promise a major that you do not have, but denying a major when you have one works quite often.

Here was another example
MP, Robot tourney, best hand South


One poor sod bid by the book, rebid 2H, responder rebid 2N, and South took a bit of a view to raise to 3N.
Spade to the Ace, Club to the T and J. Heart to the Ace. Club to the Q and K. Club back and goodnight.
He was probably a bit philosophical at the 25% misfortune of both Club finesses failing, but it must have smarted a bit when he found he got 0% of the matchpoints. OK, leaving it in 2N would have netted an average-ish result, but 3N was not that bad a spot.

At my table (91%), the bidding and play replicated by one other player who had the same idea, it went (uncontested)
1N-2C-2D-2N-3N

Spade lead, and then, you've guessed it, Heart back and continuation.


Doesn't always work so sweet, of course.
Psych (pron. saik): A gross and deliberate misstatement of honour strength and/or suit length. Expressly permitted under Law 73E but forbidden contrary to that law by Acol club tourneys.

Psyche (pron. sahy-kee): The human soul, spirit or mind (derived, personification thereof, beloved of Eros, Greek myth).
Masterminding (pron. mPosted ImagesPosted ImagetPosted Imager-mPosted ImagendPosted Imageing) tr. v. - Any bid made by bridge player with which partner disagrees.
