Your link tries to open a file with a .lin extension, which has no program association on my machine. I think that if you link to "movie" rather than "lin" in myhands it is more compatible.
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.

Very weird. 2 robots having a misunderstanding with each other :) (if the LIN content is correct....)

I think this is another hand where GIB doesn't like any of his choices for bids, so he passes.

It does make me ask
a) does the bot play anything like X=double negative, P=waiting, over 2c (2s)?
b) why didn't East just bid those hearts? Afraid of being passed in 3H?

Obviously West's pass is a bug, no comment needed. I am fine with the first pass by E, but then I would settle for a simple 4H, showing some values but needing significant extras for slam.

With GIB's current programming we have the unfortunate self-exacerbating problem that GIB cuebids too frequently on hands where a simple suit bid would be better, and that GIB's ability to interpret and act intelligently after partner's cuebid is extremely limited (and that is an understatement).

Hi
I of course know you are a USA expert.
Here is your hand diagram.


- " a) does the bot play anything like X=double negative, P=waiting, over 2c (2s)?"

The exact explanations are
pass= not suit call, forcing.
double=penalty double --- 5+,8+TPs,forcing.
Please see my evidence hand :

Result : 2Nx-1

Hoping BBO Gib experts improve 2 system as soon as possible.



- " b) why didn't East just bid those hearts? Afraid of being passed in 3H?"

I think this is a bug.
Here I replayed this hand, got same result.
