In Response To: Praxis Position (Stanley E. Richards)

GNU 2 ply takes and gets sent to B as it thinks the take is clear. (Again overvaluing most any game with 1 anchor likely needing to hit to win) Snowie 4 is also dining with GNU and thinking the take is clear.

The score (after 0 games) is: gnubg 0, user 0 (match to 11 points)

Move number 3: user on roll, cube decision?

Pip counts: gnubg 125, user 110
Position ID: 2naBATDm3IgHAA Match ID: cAlgAQAAAAAA
