Hi folks,
can someone check the attached file please?
The story: I was playing around a little bit with basic bearoffs and
made a session of 2roll - 5roll (cube in the middle/player owns cube).
1.After analysing the session, gnubg incorrectly gives 5 errors in the
session statitistics (3 missed doubles in game 1, 3 missed doubles in
game 2) and doesn't annotate the second game with questionmarks.
2. GNU Backgammon Position ID: 3wEAAL4DAAAAAA

Cube analysis
2-ply cubeless equity +0.494
0.747 0.000 0.000 - 0.253 0.000 0.000
Cubeful equities:
1. No double +0.915
2. Double, pass +1.000 ( +0.085)
3. Double, take +0.915 ( +0.000)
Proper cube action: Optional redouble, take
^^^^^^^^
I didn't play bg for a year now, but did I miss some new overwhelming
theory? Years ago I learned this is a (re-)double/take, but not
optional.
Ciao

PS. I'm using the default bearoff databases (put into
