Hi Peter,

GNU backgammon is a world class opponent and assumes, in a sense at
least, that your and its strengths are equal. GNU backgammon's doubles
are based on this assumption. So while it in a given position would
win e.g. 60% of the games when playing against itself, it is likely to
win e.g. 80% (or even 99%) of the games when playing against you.
Especially in a complicated position like the one you report.

The bottom line is keep studying, for example by enabling the build in
tutor function.
