Genuine choices

In Response To: Genuine choices (David Rockwell)

The 2-ply v 0-ply rollout I have does not give support to the idea that the play after 32S is easier in general than play resulting from 32D. I think it suggests the opposite.

The score (after 0 games) is: gnubg 0-ply 0, gnubg 2-ply 0

Move number 1: gnubg 2-ply to play 23

gnubg 0-ply	167
gnubg 2-ply	167
Position ID: 4HPwATDgc/ABMA Match ID: cAkNAAAAAAAA

• gnubg 2-ply moves 13/11 13/10

Alert: doubtful move ( -0.016)
