This hand is from Challenges, it seems that Gibs would try different lead in the same hand, see another challenge.

GIB ducking for no reason at all has been posted a huge number of times. I think we just need to accept it's never going to be fixed.

[steve2005]

7NX player with Ace on lead, would never lead ace. BBO fixed this by coding if 7N on lead have an ace lead it. BBO did not fix whatever flaw in Gib's algorithm prevented Gib from leading the Ace.

 

This is similar situation something is prevent Gib from playing 4 higher cards that are clearly superior.

Maybe this is just in basic bots, but it still should be fixed.

I would assume BBO is embarrassed by these kinds of errors and would fix them if they could. The fact that they haven't makes me believe that GIB is hopelessly broken in key parts of the program.
