I cannot rationalize the double. Other than to suspect that no rules applied and so the bot ran a sim and double worked on its sample.

Of course, there was no real correct choice - all roads lead to failure (well, x followed by pass actually works).
Perhaps South will remind himself that upgrading notrump hands based on 4333 shape is not usually a positive EV strategy.
You must know the rules well - so that you may break them wisely!

It is easier to rationalize the deviation of the double, than to rationalize the unnecessary jump to 4S which wouldn't allow a human partner to wiggle out of the spade strain. It is not particularly relevant that nothing works on this hand except defending, however. And the upgrade to open 1NT is just plain silliness from watching too much vugraph where their range includes 14.

He nailed it. Personally, I think any EXP+ player using Negative Doubles would make one there, after all North has no problem with 3NT, 4, 4 on a 5-2 fit if it exists, 5, and 3 X if partner leaves it in.

Thanks for reporting and sorry for the quite delayed answer.

It's fixed in next ( very likely soon coming version ) v28.

Fixing the explanation to be more flexible, or fixing it so the Bot doesn't double?

Explanation is ok.

GIB will bid just 3NT as not having both majors as promised.
