I am not sure advanced BOTs are better

First of all, this looks like a negative double, but I wonder what deals the bot found, where 4♠ is better than 3N.

 

3N= 5+♠, 11-15 HCP, stop in ♦

I don't see how you can justify not bidding 3♣ holding solid clubs. Maybe if the clubs were broken like 75432, but you've got a straight flush in clubs which demands that they be bid.

3♣ is of course silly, but that's nothing to do with advanced bots. Give South a typical 5341 type shape and 4♠ appears to be consistently better than 3NT, so disagree with the subject line.

Yes, but 5341 is not the most likely distribution of opener.

 

Try with 5233/5332 or even 5224

 

In 4♠, then hand is practically only worth 3 tricks (and the same in 3N), as East is short in ♦, so no ♦.ruf

That's what the advanced bot does. It gives it a variety of hands with those shapes, and determines 4♠ is better, double dummy, more often that it isn't. I can see plenty of hands where 3NT is better, but I can also see plenty of hands where 4♠ is better.

 

Have run the numbers myself and came up with the same conclusion, so I'm not seeing an issue here.

Then I assume it is an issue in the simulation, or could it just be one of these places, where the bot is better than human?
