RE: [Bug-gnubg] Snowie 4 vs. GNU 0.13

[Albert Silver]

Ok, here are the rollout results. I did a full 720 trial rollout with
2-ply precise. I don't know whether a 3-ply would change much. Snowie 4
now thinks it is a take instead of a pass, but that it is a close call.

                                                Albert

Match to 7. Score X-O: 0-1
