To a bot, a double negative means a positive. :D
Is the word "pass" not in your vocabulary?
So many experts, not enough X cards.

I have never seen this one before, weird.
Please let me know about any questions or interest or bug reports about GIB.

Maybe Fred introduced AI into the bots, and the bot saw you play a few hands?
"Gibberish in, gibberish out. A trial judge, three sets of lawyers, and now three appellate judges cannot agree on what this law means. And we ask police officers, prosecutors, defense lawyers, and citizens to enforce or abide by it? The legislature continues to write unreadable statutes. Gibberish should not be enforced as law."

I've never seen this before either.

I had S KJ H AKQJxx D KJ C Axx
The subsequent action was:
2C-2D;2H-3C;3NT-5H;

And I passed since I don't understand what GiB was doing.

If the bot saw me play he should be more aggressive since I am passing with opening values all the time! :D

Interesting -- this bug was caused by an error in the definition of 4♥, which precluded 3♥ from being considered as an option. In GIB's simulations, 4♥ was usually passed but 3♣ gave it a better chance to get to slam.

Anyone want to offer an opinion about what 4♥ should mean here?

I think the natural way would be that 4H is a minimum hand with support (without an ace, no void, 5- HCP etc) and 3H is a forcing support.
