Pass!

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.

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.

[Siegmund]

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 : 2♠Nx-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.
