The topic of Bot's defensive opening leads has arisen many times yet each new iteration produces the same insane lead selections.
When partner has bid during an auction it should be taken as a clue to partnership defensive strength yet is consistently overlooked by Bot.
Yes, there are Bot holdings that clearly call for a lead other than partner's suit yet Bot relies on doubleton or singleton first, high card sequence second, a trump lead third, then maybeeeeeeee.....partners suit. I am sick of it!!!!!!!!!

When it comes to play of the hand, there basically is no "new" iteration". It is the same iteration because the play engine is so complex and convoluted that the current programming staff does not understand the code well enough to make changes without affecting other areas of play.

It doesn't make any difference how many times someone complains about GIB leads if there are no programming changes to the play engine because the same code is copied and pasted to the next version.

IIRC, there was a change where GIB would lead an ace against 7NT or something like that several years ago, but that may have been specifically coded to override the play engine for the opening lead.

so the short answer is that Bot's defensive opening leads will remain UGH and costing a defensive trick more than 25% of the time that
a bid suit is not BOT's chosen opening lead.
