Yes, Rainbow Serpent thinks that is about right. Although there is no guarantee, there is not anything shorter. I think some programs you can give a command like "Skip anything longer than Mate in 18." Well you probably know that. You can do that, because that is part of how a specialized Mate program works. But with a M18, you probably save not very much in the search. Rainbow Serpent does not have any special settings like that.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

I found a move in 18 by advancing move by move.
13.Qf6 is one move shorter than 13.Qc2+ :
