Gnubg 2-ply plays 20/10(2). Lenny's comment entails that if the 2 point spare is moved elsewhere, even to the 4 point which allows Blue to play a 2-1, Gnubg 2-ply makes the board. If it's on the 4 or 5 point, Gnubg prefers boardmaking by about 0.020; if it's on the 6 point, by 0.060; on the 7 point, by about 0.110.
