In Response To: -2:-3 early 62 (David Montgomery)

I played 5* 4* otb in a dailygammon tournament match. I was surprised to get dinged for a .119 gnubg error on 2-ply eval. 4-ply says .116. But the rollout has 5* 4* as just a bit worse than 3.

The score (after 0 games) is: top 4, bottom 5 (match to 7 points)

Move number 4: bottom to play 62

top	156
bottom	154
Position ID: sGfwAQXg88gBBg Match ID: cAnrAEAAKAAA

• bottom moves 11/5* 6/4*
