I'd never seen GIB execute the duck here before...I wasn't sure it would. Well done.

You played lazily, next time win in dummy and run diamond winners, no doubt you will get a heart pitch or two from one or both gibs. Remember, gib does not account for you misguessing anything, so pitching from Jxx of hearts is free as far as it is concerned.

Since GIB thinks declarer is playing double dummy, it's very interesting that it finds this duck. A human does it to hide the location of the Ace and hope declarer misguesses on the next round of hearts, as you did. But GIB never expects you to misguess, so what's the point of holding up?
I think this may be a case where it thinks it makes no difference, so it chooses randomly. If I understand the code correctly, it plays high with 75% probability.

Nope, I misread the code. That 75% probability is only for declarer, not defenders. Defenders select equally among equivalent cards, unless it's a signalling situation, then they choose the card to appropriate for the signal.

So what is the definition of signaling situations in gib's code?

Signalling situations:
1. You aren't declarer.
2. You aren't leading.
3. It's not trump.
4. You have no chance of winning the trick.
5. You haven't signalled in this suit yet.
6. You signal.
7. You have at least two cards to play.
8. This card isn't an honor.
I'm hoping to try to teach it about giving suit preference when giving a ruff.

Thanks. This information is very useful. That means it gives signals on the first card of the suit played if it doesn't or can't win the trick.
