Hi folks, in Hardy's forum http://www.hardyhuebener.de/forum/index.php?topic=462.0 a strange evaluation occured: GNU Backgammon Position ID: sO02gCC+AAAAAA Match ID : cImlAAAAGAAA +24-23-22-21-20-19------18-17-16-15-14-13-+ O: lazydawg | O O | | O O O O | 0 points | O O | | O O O O | | | | O | | | | | | | | | | |BAR| |v 5 point match (Cube: 1) X | X | | | XX | X | | | XX | X | | | XX | X | | | Rolled 31 XX | O X X O | | | 3 points +-1--2--3--4--5--6-------7--8--9-10-11-12-+ X: takforfisk 1.

Is this an outcome of gnubgs bad treatment of outer primes starting at the 5-point?
