ok?
Are the bots built not to fall for mate in one

Milica, Fabian, juan, and Noel all fall for scholars mate if u try a few times. Elani falls for it rarely.

All mates are, eventually, mates in one ...so every player and engine "falls" for them.
The concept of "mate in X" is a human conceit based on human calculation abilities...engines follow this premise because human programmed them to, but ultimately, a position is either drawn, or is already a forced mate whether a human or engine can calculate far enough ahead or not.
Yes, I know this reply is wasted here...
Wayne bot is not falling for scholars mate
