Hi Michael & Ian,
Yes the "Show higher die on left" box is checked in the Dice tab of the options panel. I also thought maybe my weights file was missing or corrupt but the Help-->About-->Evaluation_Engine lists all the nets as "version 0.15". I use the pre-defined setting of World Class for everything, analysis, evaluation, and the player setting of GnuBG. I verified that all settings were correct. No this is not a Windows build. I am using a Macintosh Powerbook G4 and my build setup has not changed recently and I am using the same optimization settings that I have always used. I keep a copy of the gnubg module on my desktop and frequently update it using the built-in CVS control of BBEdit. I did recently upgrade BBEdit but I don't know how that could have corrupted any files. I will pull a new copy of the gnubg module using my command line CVS client and re-build GnuBG and let you know how that goes.
                        Take care,

Hello Developers,
I just built gnubg from CVS as of June 15, 2009 05:07 GMT and the
program is behaving rather strangely. It is playing poorly, and
making tutor recommendations which are clearly wrong.

I just pulled latest CVS, built on my MAC. Made sure evals were set to 2 ply/2ply (even tried 0ply/0ply) and started money sessions with Tutor mode
on and Manual dice.

It believes that the normal 8/3 6/3 play is correct (even on 0 ply). I also
don't experience the problem

Is it possible your weights file is corrupt? Is it possible there is a
problem with the Settings/Evaluations (Make sure the plies are correct and
there is no noise)?? (Can you verify)

I tried the test with high die on right, and clicked on the top 8pt and it moved correctly to the 3pt. Which is what you'd expect. This is likely do to an option that is wrong. Go to Settings/Options..., click the "Dice" tab. I am betting that you hav no checkmark in "Show higher die on left". If not, check it and then try your test again. If I remove the checkmark I see the
behavior you describe.

Is this a windows build you built?

Gnubg always plays the left die first by default. Have you checked the
option to show the higher die on the left? Check
Settings...Options...Dice...Show high die on left.

(To developers: I suggest that this setting be hard-coded and removed
from the interface. Does it help anybody to have the alternatives

What weights file are you using? It sounds like you might have an out
of date weights file, or it may even be missing altogether. Check
Help...About...Evaluation Engine. The weights file should be 0.15.
