GNU

impressed. I don't think it (yet?) matches Snowie, especially when it comes
to user interface and stuff like that. I do however have a few questions:
After analyzing a match I'm told (among other things) that I've done
mistakes. Is there any way to see what mistakes I've done?
Is there a way to make GNU "sort" the dice, i.e. make the bigger die appear
first. If I roll 13 I automatically read this as a 31 so instead of making
the 5-point I end up moving 8/7, 6/3.
Is it possible to right-click when you just want to bear two checkers off?
When doing rollouts I often find that the cubeless vs cubeful results differ
quite a bit. Is the cubeful equity always more correct?
Will it be possible to save & open matches & positions directly to/from
Snowie formats?
When setting up positions for analysis is it possible to change the match
length without changing the position? Or turn a match position into a money
game position?
Will there be some kind of user manual in the near future?

They are marked with !, !!, ? or !? in the game list (windows->game list).

Settings->Appearence->General->Show higher die on the left

No, but you may use Settings->Options->Automatic->Bearoff.

Not necesarily, but they take the value of holding the cube into
account. In general, you cannot compare cubeful and cubeless equities.
For example,
GNU Backgammon Position ID: DwAA4AEAAAAAAA
Match ID : cAkAAAAAAAAA
+13-14-15-16-17-18------19-20-21-22-23-24-+ O: gnubg
| | | O | OOO 0 points
| | | O | OO
| | | O | OO
| | | O | OO
| | | | OO
v| |BAR| | (Cube: 1)
| | | | XX
| | | X | XX
| | | X | XX
| | | X | XX On roll
| | | X | XXX 0 points
+12-11-10--9--8--7-------6--5--4--3--2--1-+ X: jth
The cubeless equity is +0.722, but the cubeful equity is:
Centered cube: +1.000 (double, pass)
X owns cube : +1.000 (redouble, pass)
O owns cube : +0.722
So for centered and X owning cube the cubeless equity is 0.278 from the
"true" equity.

No, the Snowie formats are binary and not documented anywhere. You can
export matches from Snowie in .mat (Jellyfish format) and import those
into gnubg, but any analysis will be lost.

No, but it will be -- wait a month or so.

Well, if somebody writes it. Achim Mueller is coordinating the work on
the manual. Please write to bug-gnubg(at)gnu(dot)org if you would like
to assist with the manual.

You can get a basic faq at http://mole.dnsalias.org/~acepoint/. I
don't know if it's already built in the windows gnubg.

I have to admit that I was quite busy in the past few weeks. Work on
documentation will go on in August (but you guys are coding too fast
;-)).
