I'll do some testing of this, but it's not always easy to see the
difference. One detail: It's true that the 1-ply is the worst (IMHO) ply
depth, however, in my experience, the 3-ply is definitely stronger than
the 2-ply. This has been confirmed by numerous rollouts, as well as
errors pointed out by Snowie. As a rule its evaluation is more precise,
and it is able to find the correct moves many times that it might miss
at 2 plies. This includes its chronic problems with bearoff against more
than 1 checker on the bar.

Correct. Using 1-ply may often remove the correct move, so that's why we
generally skip pruning at odd plies.
The old setup has a setting "Skip pruning at 1-ply" or something similar
for the same reason.
Also, note that the default move filters are not "tested". I've just
committed some values that seemed reasonable. I would very much like
some feedback regarding them. Is the "small" move filter really small
etc etc?!"
