The score is: White 5, Blue 9 (match to 11 points). Blue on roll

Position ID: tq0iAQOU+z4AAA Match ID: cAlgAVAASAAA

Blue's position here is one pip worse than the one in the Stick/Mochy/Falafel/Sleepy match. Move a checker from the 7 point to the 6 point to get the original position.

As is often the case with Gnubg analysis of common holding games, 2-ply evaluation is too pessimistic, 3-ply evaluation too optimistic.
