Sorry for not adding nothing to usefull to the thread.
But I found this comment very interesting and I would
like emphasize it.
Can you give us some details about it?
This result happened when playing "less understood opponents,"
as opposed to play against GNU Go (SlugGo's base engine).
I cannot be absolutely sure, but this is how we reasoned the result:
In these cases, decisions made based upon the deeper lookahead
were based upon boards of decreasing likelihood. A medium depth
gave the best winning percentage. A plot of winning percentage
against search depth clearly rose and then fell.
Cheers,
David
